(Mount-face)

1. NFA31G has 4 circuits noise filter in 3.2x1.6mm

size with 0.8mm pitch. High density mounting is

available.

2. 3 terminal structure is achived excellent high

frequency performance.

(in mm)

0.05 min.

3. Distributed constant circuit realizes smooth

change of impedance which prevents reflection of

signal and distortion of wave shape.

4. NFA31G series is effective in the line where

ground is not stable, because the resistance

element in the filter absorb noise and return it

to ground line.

"ꢀHigh-speed signal application EMIFILr are high perfor-

mance EMI suppression filters which increase the slope

of insertion loss frequency characteristic curves (shape

factor), thereby improving noise and signal separation.

These are used for high speed signal applications in

which noise and signal frequency approach the same

value.

[Comparison of Insertion Loss Characteristics]

NFW31S

Conventional Type

To avoid the elimination of both the noise and specific

signal components, 3-terminal capacitors and other

components are applied.

An NFW31S with a built-in capacitor and an inductor type

BLM--B are available.

3. Standard Soldering Conditions

(1) SOLDERING METHODS

Allowable Flow Soldering Temperature and Time

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.

(2) SOLDERING TEMPERATURE AND TIME

To prevent external electrode solder leaching and

performance deterioration, solder within the temperature

and time combinations illustrated by the slanted lines in

the following graphs. If soldering is repeated, please note

that the allowed time is the accumulated time.

(4) REWORKING WITH SOLDER IRON

The following conditions must be strictly followed when

using a soldering iron.

Pre-heating

: 150°C 60 second Min.

Soldering iron power output

: 30W Max.

Temperature of soldering iron tip : 280°C Max.

Soldering time : 10 second Max.

For additional methods of reworking with soldering iron,

please contact Murata engineering.

4. Cleaning

Following conditions should be observed when cleaning

chip EMI filter.

b) Aqueous cleaning agent

Surface active agent (Clean Thru 750H)

Hydrocarbon (Techno Cleaner 335)

(1) Cleaning Temperature : 60degree C max. (40degree C

max. for CFC alternatives and alcohol cleaning agents)

(2) Ultrasonic

High grade alcohol (Pine Alpha ST-100S)

Alkaline saponifier ( Aqua Cleaner 240 -cleaner should

be diluted within 20% using deionized water.)

(4) Ensure that flux residue is completely removed.

Component should be thoroughly dried after aqueous

agent has been removed with deionized water.

(5) Some products may become slightly whitened.

However, product performance or usage is not affected.

For additional cleaning methods, please contact Murata

engineering.

Output

Duration : 5 minutes max.

Frequency : 28kHz to 40kHz

(3) Cleaning agent

The following list of cleaning agents have been tested on

the individual components. Evaluation of final assembly

should be completed prior to production.
