Chip Ferrite Beads BLM18 Series
BLM18A Series
0.4±0.2
■ Features
The chip ferrite beads BLM series is designed to
function nearly as a resistor at noise frequencies,
which greatly reduces the possibility of resonance and
leaves signal wave forms undistorted.
1.6±0.15
The BLM series is effective in circuits without stable
ground lines because the BLM series does not need a
connection to ground.
0.8±0.15
The nickel barrier structure of the external
electrodes provides excellent solder heat resistance.
BLM_A series generates an impedance from the
relatively low frequencies. Therefore BLM_A series is
effective in noise suppression in a wide frequency
range (30MHz to several hundred MHz).

■ Features
The chip ferrite beads BLM series is designed to
function nearly as a resistor at noise frequencies,
which greatly reduces the possibility of resonance and
leaves signal wave forms undistorted.
1.6±0.15
The BLM series is effective in circuits without stable
ground lines because the BLM series does not need a
connection to ground.
0.8±0.15
The nickel barrier structure of the external
electrodes provides excellent solder heat resistance.
The BLM_B series can minimize attenuation of the
signal waveform due to its sharp impedance
characteristics. Various impedances are available to
match signal frequency.

BLM18P Series
0.4±0.2
■ Features
The chip ferrite beads BLM series is designed to
function nearly as a resistor at noise frequencies,
which greatly reduces the possibility of resonance and
leaves signal wave forms undistorted.
1.6±0.15
The BLM series is effective in circuits without stable
ground lines because the BLM series does not need a
connection to ground.
0.8±0.15
The nickel barrier structure of the external
electrodes provides excellent solder heat resistance.
The BLM_P series can be used in high current circuits
due to its low DC resistance.

Specifications and Test Methods
■ Measuring Method for Common Mode Impedance
Measured common mode impedance may include
measurement error due to stray capacitance, residual
inductance of test fixture.
To correct this error, the common mode impedance should
be calculated as follows;
(1) Measure admittance of the fixture (opened), Go Bo.
(2) Measure impedance of the fixture (shorted), Rs Xs.
(3) Measure admittance of the specimen, Gm Bm.
(4) Calculate corrected impedance |Z| using the formula
below.
3
|Z| = (Rx2+Xx2)1/2
Where
Gm - Go
Rx =
Xx =
- Rs
- Xs
(Gm-Go)2 + (Bm-Bo)2

voltage as this may create excessive heat and
deteriorate the insulation resistance.
■ !Caution (Soldering and Mounting)
Please provide special attention when mounting chip
"EMIFIL" (BLM_P) series in close proximity to other
products that radiate heat.
The heat generated by other products may deteriorate
the insulation resistance and cause excessive heat in
this component.

■ Notice (Storage and Operating Condition)
< Operating Environment >
2. Storage conditions
Do not use products in a chemical atmosphere such as
chlorine gas, acid or sulfide gas.
(1) Storage temperature : -10 to 40 degree C
Relative humidity : 30 to 70%
< Storage and Handling requirements >
1. Storage Period
Avoid sudden changes in temperature and humidity.
(2) Do not store products in a chemical atmosphere
such as chlorine gas, acid or sulfide gas.
BLM series should be used within 6 months, the
other series should be used within 12 months.
Products to be used after this period should be
checked for solderability.
■ Notice (Rating)
Noise suppression levels resulting from Murata's EMI
suppression filters "EMIFIL" may vary, depending on
the circuits and ICs used, type of noise, mounting
pattern, lead wire length, mounting location, and
other operating conditions. Be sure to check and
confirm in advance the noise suppression effect of
each filter, in actual circuits, etc. before applying
the filter in a commercial-purpose equipment design.

Soldering and Mounting
1. Standard Land Pattern Dimensions
NFp series suppress noise by conducting the high-frequency noise element to ground. Therefore, to obtain maximum
performance from these filters, the ground pattern should be made as large as possible during the PCB design stage. As
shown in the right, one side of the PCB is used for chip mounting, and the other is used for grounding.
Small diameter feedthrough holes are then used to connect the grounds on each side of the PCB. This reduces the high-
frequency impedance of the grounding and maximizes the filter's performance.

2. Solder Paste Printing and Adhesive Application
When reflow soldering the chip EMI suppression filter, the
printing must be conducted in accordance with the
following cream solder printing conditions.
copper foil patterns.
When flow soldering the EMI suppression filter, apply the
adhesive in accordance with the following conditions.
If too much adhesive is applied, then it may overflow into
the land or termination areas and yield poor solderability.
In contrast, if insufficient adhesive is applied, or if the
adhesive is not sufficiently hardened, then the chip may
become detached during flow soldering process.
If too much solder is applied, the chip will be prone to
damage by mechanical and thermal stress from the PCB
and may crack. In contrast, if too little solder is applied,
there is the potential that the termination strength will be
insufficient, creating the potential for detachment.
Standard land dimensions should be used for resist and

3. Standard Soldering Conditions
(1) Soldering Methods
Use flow and reflow soldering methods only.
Use standard soldering conditions when soldering chip
EMI suppression filters.
In cases where several different parts are soldered, each
having different soldering conditions, use those
conditions requiring the least heat and minimum time.
Solder : H60A H63A solder (JIS Z 3238)
In case of lead-free solder, use Sn-3.0Ag-0.5Cu
solder
3
Flux :
o Use Rosin-based flux (when using RA type solder, clean
products sufficiently to avoid residual flux.
o Do not use strong acidic flux (with chlorine content
exceeding 0.20wt%)
o Do not use water-soluble flux.

Noise Suppression Principles by DC EMIFILr
1. Function of DC EMI Suppression Filters
DC EMI suppression filters absorb and eliminate high fre-
quency noise which may produce electromagnetic
interference in PC board circuits.
These filters are used in secondary circuits, and are small
in size and light in weight, which further enhances their
excellent noise suppression functions.
Chip and adhesive type filters can be mounted on PC
boards automatically.
These filters are effective in the suppression of radiation
noise in computers, peripheral equipment, and digital
circuit application equipment (including various types of
microcomputer application equipment), and function to
suppress noise in audio/visual equipment, which uses
digital memory chips and DSP.
These filters are also effective for improving the noise
immunity of equipment used in noisy environments (such
as electronic equipment for automobiles).
2. Noise Filter Suppression Principles
Generally, noise problems occur when the noise source
[EMI Propagation Mode and Model of Noise Filter Suppression]
and electronic equipment sensitive to the influence of
noise are located in close proximity to one another.
r
In such situations, as shown in Figure at right, noise is

conducted through a conductor, which produces an

inductive field around the noise source.
To overcome such noise problems, it is preferable to
reduce the amount of noise generated by the noise
source or improve the noise resistance of adjacent
equipment.

In order to satisfy equipment performance specifications
and eliminate noise effectively at the same time, however,
it is customary to reduce the amount of noise generated
by the noise source, if it can't be eliminated altogether.

3. Configuration of EMI Suppression Filters (DC)
DC EMI suppression filters are used to suppress noise
produced by conductors. Noise radiation can be
suppressed, if it is eliminated with a filter in advance.
Generally, such noise suppression is achieved with DC
EMI suppression filters, according to the capacitive and
inductive frequency characteristics of the respective
conductors in the circuit.
Filters of this kind can be roughly divided into those:
(1) employing a capacitor,
(2) employing an inductor,
(3) employing a capacitor and inductor combination.

4. Capacitive Noise Suppression
When a capacitor is connected (bypass capacitor) to
[Capacitive Noise Suppression]
ground from a noisy signal line or power line, the circuit
impedance decreases as the frequency increases. Since
noise is a high frequency phenomenon, it flows to ground

if a capacitor has been connected to ground, thereby
making it possible to eliminate noise. (See Fig.)
EMI suppression filters employing a capacitor in this way
are used to eliminate this type of noise.

5. High frequency Capacitor Characteristics Used
for EMI Suppression Filters
[Equivalent circuit of general-purpose capacitor and
three terminal capacitor in the high frequency area
and comparison of insertion loss]
Even general-purpose capacitors can be used for noise
suppression. However, since noise has an extremely high
frequency range, general-purpose capacitors may not
function as effective bypass capacitors, due to the large
residual inductance built into the capacitor.
(a) Equivalent circuit of capacitors which is concerning ESL effect.
All the capacitors used in Murata's EMI suppression
filters employ a three terminal structure or thru-type
structure, which functions effectively even at high
frequencies, thereby minimizing the influence of residual
inductance. Consequently, an effective filter circuit can be
formed even at frequencies exceeding 1GHz.

6. Inductive Noise Suppression
When an inductor is inserted in series in a noise
producing circuit (See Fig.), its impedance increases with
frequency. In this configuration it is possible to attenuate
and eliminate noise components (high frequency
components). The Murata EMI suppression filter
functions in this way.

7. Characteristics of Inductors Used
in EMI Suppression Filters
[Equivalent Circuit]
General-purpose inductors also function to suppress
R(f)
noise when configured in series with a noise producing
circuit. However, when general-purpose inductors are
used, resonance may result in peripheral circuits, signal
(Resistance element becomes dominant at high frequency.)
wave forms may become distorted, and satisfactory
impedance may not be obtained at noise frequencies
(due to insufficient high frequency impedance
[Example of impedance frequency characteristics of
characteristics).
inductor type EMIFILr]
The inductors used for Murata's EMI suppression filters
are designed to function nearly as a resistor at noise fre-
BLM18AG102
quencies, which greatly reduces the possibility of
1200
resonance and leaves signal wave forms undistorted.
Z
And since sufficient impedance is obtained for
900
frequencies ranging to hundreds of MHz, these
R
specifically designed inductors operate effectively to
600
suppress high-frequency noise. (See Fig.)

8. Capacitive-Inductive EMI Suppression Filters
If capacitive and inductive suppression characteristics are
combined, it is possible to configure a much higher
performance filter. In signal circuit applications where this
combination is applied, noise suppression effects which
have little influence on the signal wave form become
possible.
This type of filter is also effective in the suppression of
high-speed signal circuit noise. When used in DC power
circuits, capacitive-inductive filters prevent resonance
from occurring in peripheral circuits, thus making it
possible to achieve significant noise suppression under
normal service conditions.
9. Other EMI Suppression Filters
In addition to the capacitive-inductive filter, Murata also
has a common mode choke coil, effective for common
mode noise suppression.
Murata also has a range of built-in filter connectors which
greatly reduce filter mounting space requirements.

10. Expressing EMI Suppression Filter Effects
EMI Suppression Filter effects are expressed in terms of
[Measuring Circuit of Insertion Loss]
the insertion loss measured in the circuit, normally
specified in MIL-STD 220A. As shown in the 50Ω
Measuring Circuit of Insertion Loss
impedance circuit in the Figure at right, insertion loss is

represented by the logarithmic ratio of the circuit output
voltage with and without a filter in the circuit, which is

multiplied by 20 and expressed in dB.
Therefore, an insertion loss of 20dB indicates an output

indicates an output voltage ratio (B/C) of 1/100.
