Tantalum Surface Mount Capacitors – High Reliability

T493 Commercial Off-The-Shelf (COTS)

MnO

(CWR11 Style)

Overview

The KEMET T493 is designed for the commercial off-

the-shelf (COTS) requirements of military and aerospace

applications. The T493 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 simulatedbBreakdown

voltage (SBDV) screening options to improve long term

reliability. Standard, low, and ultra-low ESR options are

available. All lots of T493 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 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 25 V and

higher rated voltage). Please contact KEMET for details on

ordering other part types with these capabilities.

The KEMET patented simulated breakdown screening (SBDS)

is a nondestructive testing technique that simulates the

breakdown voltage (BDV) of a capacitor, without the 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. 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
