Wet Tantalum Capacitors

Tantalum-Case with Glass-to-Tantalum Hermetic Seal For-55

°C to + 200°C Operation

FEATURES

Standard and Extended Ratings.

Model 135D tantalum-case tantalum electrolytic capacitors

incorporate the advantages of all the varieties of

electrolytic capacitors and eliminate most of the

disadvantages. These units have a 3 volt reverse voltage

capability at + 85

°C and a higher ripple current capability

than any other electrolytic type

with similar combinations of capacitance and case size.

Designed for the aerospace applications, this capacitor

was developed under partial sponsorship of the Marshall

Space Flight Center, National Aeronautics and Space

Administration. The capacitors have a high resistance to

damage from shock and vibration. Extended range ratings

are available.

Model 135D capacitors are commercial equivalents of

Military Style CLR79 and CLR81, designed to meet the

performance requirements of Military Specification MIL-C-

39006/22/25. Capacitors to meet MIL-C-39006/22/25

should be ordered by part numbers shown in that

specification.

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.

Following life test:

1. DCL, measured at + 85

°C rated voltage, shall not be in

excess of the original requirement..

2. The equivalent series resistance shall not exceed 150%

of the initial requirement.

3. Change in capacitance shall not exceed 10% from the

initial measurement.

PERFORMANCE CHARACTERISTICS

Operating Temperature: - 55

°C to + 85°C. (To + 200°C

with voltage derating.)

Capacitance Tolerance: At 120 Hz, + 25

°C. ± 20%

standard.

± 10%, ± 5% available as special.

DC Leakage Current (DCL Max.):

At + 25

the values listed in the Standard Ratings Tables.

*For insulated parts, add 0.007" [0.178] to the diameter. The insulation shall lapover the ends of the capacitor body.
