Tantalum Through-Hole Capacitors – Hermetically Sealed
T255 Axial High Temperature Solder (CSR33 Style)
Overview
The KEMET T255 High Temperature Solder Series of solid
tantalum capacitors offers high capacitance-to-volume
ratios and is available in standard MIL style A, B, C, and D
cases. These devices meet or exceed the environmental
and mechanical requirements of MIL–PRF–39003.
Designed to operate from −55°C to +125°C, the internal
design of these capacitors, as well as the hermetic seal,
includes high temperature solder (minimum melting point
of 221°C). The content of tin in the solder does not exceed
97%. This assembly is especially suited for temperature
conditions where solder may fail due to undesirable solder
reflow.
The T255 Series exhibits exceptionally low DC leakage,
dissipation factor and impedance characteristics. These
parts are available in Style CSR33 per MIL–PRF–39003/06.
Benefits
• Internal construction solder to resist up to 221°C
• Failure rate options: Graded – B, C, D, and G, and
Exponential – M, P, R, and S
• Surge current options D, E, and F
•
Taped and reeled per EIA Specification RS-296
• Marking per MIL–STD–1285
•
Qualified to MIL–PRF–39003 (CSR33 Style)
•
Operating temperature range of −55°C to +125˚C
•
Capacitance values of 1.2 μF to 1,000 μF
• Tolerances of ±10%, and ±20%
• Voltage rating of 6 VDC – 50 VDC
• Marking per MIL–STD–1285
• Case sizes: A, B, C, D

Applications
These capacitors are ideal for coupling, bypass, filtering and timing circuits, and are excellent substitutes for wet tantalums
in low voltage applications.
