MIL-PRF (CWR Style) Established Reliability

T492 CWR11 Style MIL-PRF-55365/8

Overview

The KEMET T492 series is approved to MIL-PRF-55365/8

(CWR11) with Weibull failure rates of B level (0.1% failures per

1000 hours), C level (0.01% failures per 1000 hours), or D level

(0.001% failures per 1000 hours). This CWR11 product is a

precision-molded device, with compliant terminations and indelible

laser marking. This is the military version of the global IEC/EIA

standard represented by KEMET's T491 Series. Tape and reeling

per EIA 481-1 is standard.

Beneﬁts

Applications

Typical applications include decoupling and ﬁltering in military and

aerospace applications requiring CWR11 devices.

• Established reliability options

• Taped and reeled per EIA 481-1

• Symmetrical, compliant terminations

• Laser-marked case

• 100% surge current test available on all case sizes

• Qualiﬁed to MIL-PRF-55365/8, Style CWR11

• Termination options B, C, H, K

• Weibull failure options B, C, and D

• Voltage rating of 4-50 VDC

• Operating temperature range of -55˚C to +125˚C

Environmental Compliance

RoHS Compliant (6/6)* according to Directive 2002/95/EC

*When ordered with 100% Sn Solder

Reverse Voltage

Solid tantalum capacitors are polar devices and may be permanently damaged or destroyed if connected with the wrong polarity. The

positive terminal is identiﬁed on the capacitor body by a stripe plus in some cases a beveled edge. A small degree of transient reverse

voltage is permissible for short periods per the table. The capacitors should not be operated continuously in reverse mode, even within

these limits.

Density Level A: For low-density product applications. Recommended for wave solder applications and provides a wider process window for reﬂow solder

processes.

Density Level B: For products with a moderate level of component density. Provides a robust solder attachment condition for reﬂow solder processes.

Density Level C: For high component density product applications. Before adapting the minimum land pattern variations the user should perform qualiﬁcation

testing based on the conditions outlined in IPC standard 7351 (IPC-7351).

¹ Height of these chips may create problems in wave soldering.

² Land pattern geometry is too small for silkscreen outline.

KEMET’s families of surface mount capacitors are compatible

with wave (single or dual), convection, IR or vapor phase reﬂow

techniques. Preheating of these components is recommended

to avoid extreme thermal stress. KEMET's recommended

proﬁle conditions for convection and IR reﬂow reﬂect the

proﬁle conditions of the IPC/J-STD-020D standard for moisture

sensitivity testing. The devices can safely withstand a maximum

of three reﬂow passes at these conditions.

Hand soldering should be performed with care due to the difﬁculty

in process control. If performed, care should be taken to avoid

contact of the soldering iron to the molded case. The iron should

be used to heat the solder pad, applying solder between the pad

and the termination, until reﬂow occurs. Once reﬂow occurred, the

iron should be removed immediately. "Wiping" the edges of a chip

and heating the top surface is not recommended.

Storage

Tantalum chip capacitors should be stored in normal working environments. While the chips themselves are quite robust in other

environments, solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long term

storage. In addition, packaging materials will be degraded by high temperature - reels may soften or warp, and tape peel force may

increase. KEMET recommends that maximum storage temperature not exceed 40ºC, and maximum storage humidity not exceed

60% relative humidity. In addition, temperature ﬂuctuations should be minimized to avoid condensation on the parts, and atmospheres

should be free of chlorine and sulphur bearing compounds. For optimized solderability, chip stock should be used promptly, preferably

within three years of receipt.
