Tantalum Surface Mount Capacitors – High Reliability

T493 Series Commercial Off-The-Shelf (COTS)

MnO

(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
