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 DLA 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 tantalum's have 1.5 orders of magnitude degradation in
leakage current. F-Tech is currently available for the 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
