Tantalum Surface Mount Capacitors – Space Grade
T493 Space Grade High Reliability Alternative (HRA)
MnO
2
(CWR11 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
• Standard case sizes per EIA 535BAAC
• Termination finishes options per MIL–PRF–55365:
Gold Plated B, Hot Solder Dipped C, Solder Plated H,
Solder Fused K
• Weibull Grading C (0.01%/1,000 hours)
• Surge current testing available per MIL–PRF–55365:
10 cycles at 25°C, 10 cycles at −55°C and +85°C
• Standard and low ESR options available
Applications
Typical applications include decoupling and filtering in defense and aerospace applications.
Environmental Compliance
• Halogen-free
• Epoxy compliant with UL94 V-0
• Molded Epoxy complies for outgassing testing under ASTM E 595.
