Tantalum Surface Mount Capacitors – Space Grade
T497 Space Grade High Reliability Alternative (HRA)
MnO

(CWR09/19/29 Style)
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
• Low profile case sizes
• 100% thermal shock
• 100% surge current test available on all case sizes
• Various termination finishes available
• Weibull Grading C (0.01%/1,000 hours)
Applications
Typical applications include decoupling and filtering in medical, defense, and aerospace applications.
Environmental Compliance
• Halogen-free
• Epoxy compliant with UL94 V-0
• Molded Epoxy complies for outgassing testing under ASTM E 595.
