FEATURES

Improved reliability through the use of a glass-to-tantalum

true hermetic anode seal is the prime feature of the Type

offers outstanding resistance to thermal shock.

Model 138D is the commercial equivalents of Tansitor 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.

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

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

measurement.

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

d) 20WVDC and above:

± 10% of initial measurement.

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 120Hz, + 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

hour life test at a temperature of + 85

°C or + 125°C at the

applicable rated DC working voltage.

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.
