MODEL
This is expressed in picofarads. The
first two digits are the significant figures.
The third is the number of zeros to
follow. Standard capacitance ratings
are in accordance with EIA preferred
number series wherever possible.

FEATURES
• Hermetically-sealed, axial-lead solid tantalum capacitors
• Small size and long life
• Exceptional capacitance stability and excellent resistance
to severe environmental conditions
• The military equivalent is the CSR21 which is qualified to
MIL-C-39003/09
APPLICATIONS
Designed for power supply filtering applications at above
100kHz
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.
Life Test: Capacitors shall withstand rated DC voltage
applied at + 85°C for 2000 hours or derated DC voltage
applied at + 125°C for 1000 hours.
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 ± 5%.
