TYPE 173D
Solid Tantalum Capacitors
®
Solid-Electrolyte TANTALEX Capacitors
Axial-Lead, Molded-Case
Improved Type 173D molded-case miniature axial-lead
TANTALEX® capacitors, now available in 5 sizes, are designed
for high performance automotive, industrial and commercial
electronic equipment. Precision molded in gold colored,
flame retardant, thermosetting epoxy resin, units are laser
marked for improved legibility, while the tapered end of the
case provides easy identification of the positive terminal.
Standard orders are lead taped and reeled; orders under
500 are taped only.
PERFORMANCE CHARACTERISTICS
Operating Temperature: - 55°C to + 85°C. (To + 125°C
with voltage derating.)
At + 85°C: Leakage current shall not exceed 10 times the
values listed in the Standard Ratings Tables.
At + 125°C: Leakage current shall not exceed 15 times
the values listed in the Standard Ratings Tables.
Capacitance Tolerance: At 120 Hz, + 25°C. ± 20%, ± 10%
standard. ± 5% available as special.
Life Test: Capacitors shall withstand rated DC voltage
applied at + 85°C for 2000 hours and for 1000 hours
applied at + 125°C derated voltage.
Dissipation Factor: At 120 Hz, + 25°C. Dissipation factor,
as determined from the expression 2πfRC, shall not
exceed the values listed in the Standard Ratings Tables.
Following the life test:
1. DCL shall not exceed 125% of the initial requirement.
2. Dissipation Factor shall meet the initial requirement.
3. Change in capacitance shall not exceed ± 10%.
DC Leakage Current (DCL Max.):
At + 25°C: Leakage current shall not exceed the values
listed in the Standard Ratings Tables.
