Vishay

FEATURES

• Terminations:

standard

tin/lead

(SnPb),

100 % tin (RoHS compliant) available

• Improved reliability through the use of a

glass-to-tantalum true hermetic anode seal is

the prime feature of the Type 138D sintered

offers outstanding resistance to thermal shock.

styles WT, UWT, Mallory-NACC styles TLX, TXX and

Military styles CL66, CL67, CLR65, and CLR69, designed

to

meet

the

performance

requirements

of Military

Specification

MIL-PRF-39006/09/21.

Capacitors

in

accordance with military specifications should be ordered

by their military part numbers.

PERFORMANCE CHARACTERISTICS

Operating Temperature: - 55 °C to + 85 °C and with voltage

derating to two-thirds the + 85 °C rating at + 125 °C. Use of

Type 138D capacitors for high temperature applications is

recommended.

Capacitance Tolerance: At 120 Hz, + 25 °C. ± 20 %

standard. ± 10 %, ± 5 % available as special.

DC Leakage Current (DCL Max.): At + 25 °C, + 85 °C and

+ 125 °C: Leakage current shall not exceed the values listed

in the Standard Ratings Tables.

Life Test: Capacitors are capable of withstanding a 2000 h

life test at a temperature of + 85 °C or + 125 °C at the

applicable rated DC working voltage.

Following the life test:

1. DCL shall not exceed 125 % of the original requirement.

2. The ESR shall not exceed 200 % of the initial requirement.

3. Change in capacitance value shall not exceed the

percentages below.

a) 6 WVDC Units: + 10 % to - 25 % of initial measurement.

b) 8 WVDC and 10 WVDC Units: + 10 % to - 20 % of initial

measurement.

c) 15 WVDC Units: + 10 % to - 15 % of initial measurement.

d) 20 WVDC and above: ± 10 % of initial measurement.

This is expressed

in picofarads. The

first two digits are

the significant

figures. The third

is the number of

zeros to follow

X0 = ± 20 %

X9 = ± 10 %

X5 = ± 5 %

Special Order

This is expressed in volts.

To complete the

three-digit block, zeros

precede the voltage

rating. A decimal point is

indicated by an “R”

(6R3 = 6.3 V)

Note

Packaging: The use of formed plastic trays for packaging these axial lead components is standard. Tape and reel is not recommended due to

the unit weight.
