Tantalum Surface Mount Capacitors – Space Grade
T496 Space Grade High Reliability Alternative (HRA)
Fail-Safe Fused MnO
2
Overview
KEMET's Space Grade capacitors are suitable for use by
the defense/aerospace customers in high reliability space
applications. These capacitors meet the requirements
of MIL–PRF–55365 as well as MIL–STD–1580. These
capacitors incorporate an intensive testing and screening
protocol which is customizable depending upon
customer's specific needs.
The full part number allows for designation of surge current
level (10 cycles −55°C and +85°C before and/or after
Weibull grading, 10 cycles +25°C), performance testing
level (see chart for details on available options), ESR (low
and standard), and termination finish (see description in
each series). Fused versions are available for built-in
circuit protection, as well as multi-anode designs for very
low ESR values.
Benefits
• Internal fuse protects against damaging short circuit failure
mode
• Standard case sizes B, C, D, X per EIA 535BAAC
• 100% surge current test available
• Optional gold-plated terminations
• Fuse activation, 25°C: within 1 second at fault currents of
4 amps and higher
• Continuous current capability: 0.75 amps
• Post actuation resistance, 25°C: 10 MΩ, minimum
• Test tabs on side of case bypass the capacitor element to
allow direct testing of the fuse assembly
• Weibull Grading C (0.01%/1,000 hours)
Environmental Compliance
• Halogen-free
• Epoxy compliant with UL94 V-0
• Molded Epoxy complies for outgassing testing under ASTM E 595.
