Tantalum Hermetically Sealed/Axial Through-Hole Capacitors
T255 Series High Temperature Solder
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 221ºC
• 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, Style CSR33
• 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
• 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.
