Tantalum Surface Mount Capacitors – High Reliability
T493 Series Commercial Off-The-Shelf (COTS)
MnO
2
(CWR11 Style)
Overview
The KEMET T493 Series is designed for the Commercial
Off-The-Shelf (COTS) requirements of military and aerospace
applications. This series is a surface mount product offering
various lead-frame plating options, Weibull grading options,
surge current testing, F-Tech (an improved anode manufacturing
process) and Simulated Breakdown Voltage (SBDV) screening
options to improve long term reliability. Standard, low, and
ultra-low ESR options are available. All lots of this series are
conditioned with MIL–PRF–55365 Group A testing. This series is
also approved for DSCC Drawing 07016 (please see part number
list specific to this drawing).
KEMET’s F-Tech eliminates hidden defects in the dielectric which
continue to grow in the field, causing capacitor failures. Based
on the fundamental understanding of degradation mechanisms
in tantalum and niobium capacitors, F-Tech incorporates multiple
process methodologies. Some minimize the oxygen and carbon
content in the anodes which become contaminants and can lead
to the crystallization of the anodic oxide dielectric. This process
methodology reduces the contaminants, improving quality of
the dielectric. An additional technology provides a stronger
mechanical connection point between the tantalum lead wire and
tantalum anode, enhancing robustness and product reliability. The
benefit of F-Tech is illustrated by a 2,000 hour, 85°C, 1.32 X rated
voltage accelerated life test. F-Tech parts see no degradation
while standard tantalums have 1.5 orders of magnitude
degradation in leakage current. F-Tech is currently available for
T493 Series (select D and X case capacitance values in 20 V and
higher rated voltage). Please contact KEMET for details on ordering
other part types with these capabilities.
KEMET’s patented Simulated Breakdown Screening (SBDS) is
a nondestructive testing technique that simulates the breakdown
voltage (BDV) of a capacitor without damage to its dielectric or to the
general population of capacitors. This screening identifies hidden
defects in the dielectric, providing the highest level of dielectric
testing. SBDS is based on the simulation of breakdown voltage
(BDV), the ultimate test of the dielectric in a capacitor.
Low BDV indicates defects in the dielectric, and therefore, a higher
probability of failure in the field. High BDV indicates a stronger
dielectric and high-reliability performance in the field.
This new screening method allows KEMET to identify the breakdown
voltage of each individual capacitor and provide only the strongest
capacitors from each lot.
SBDS is currently available on select part types in the T493 and
T497 Series. Please contact KEMET for details on ordering other
part types with these capabilities.
KEMET offers these technologies per the following options:
• F-Tech only
• SBDS only
• Combination of both F-Tech and SBDS for the ultimate protection
