GR500 HIGH RELIABILITY SOLID TANTALUM

Introduction

The solid tantalum capacitor has become an essential device

in circuits requiring high capacitance-voltage product and

extended environmental capability. The KEMET GR500

Graded Reliability concept has made available state-of-the-

art devices providing maximum assurance of meeting sys-

tem reliability goals. All Graded Reliability capacitors

receive meticulous attention from raw material selection

through manufacture, final inspection and shipping. Having

survived a very stringent quality control program, the result-

ing capacitors meet or exceed the most critical requirements

of space, satellite, missile and medical applications where

failure is, at best, expensive, and at worst, fatal.

KEMET is, therefore, committed to the principle of the

highest possible reliability in the manufacture and grading of

its GR500 Series capacitors.

The KEMET GR500 High Reliability concept disallows

grouping of diverse ratings and production batches to deter-

mine average failure rates. Instead, data from each and every

capacitor batch are statistically fitted to determine failure

rate on the basis of 100% life testing. Each homogeneous

production batch is “graded’’ as a single inspection lot, and

documented evidence of failure rate achieved is supplied

with the parts, providing assurance of the most sophisticated

and accurate reliability measurement method in the industry.

Basic Requirements

A. Manufacturing Environment —

It is of vital impor-

tance that high reliability electronic components be manu-

factured in an environment which provides commitment to

the philosophy of high reliability production. GR500 Series

capacitors are manufactured in a plant area that stresses this

philosophy. Manufacturing and quality control personnel

are selected for experience and competence. Extensive

training in quality and reliability assurance techniques is

provided, and motivation of personnel is heavily stressed.

Raw material and in-process inspection techniques are

especially rigid. The result is a capacitor product of inher-

ently superior quality.

B. Screening Test —

All GR500 Series capacitors are sub-

jected to a broad test program. Despite the most rigid of

quality control procedures, some variation among batches of

capacitors must be recognized. This fact is understandable

when one considers the inherent differences which derive

from the 16 to 1 ratio of operating voltages, the 20 to 1 ratio

of physical sizes, and the 60,000 to 1 ratio among capaci-

tance ratings. Maximum assurance of reliability is achieved

by maintaining batch identity from the raw material with

respect to capacitor sizes and ratings as well as material

identification. Each batch is then subjected to extensive,

non-destructive 100% screening tests as indicated below.

1. Thermal Shock —

Inherent variations exist among

the temperature coefficients of expansion of the various

materials required in the manufacture of solid tantalum

capacitors. In worst-case combinations, individual

capacitors will exhibit sensitivity to temperature excur-

sions. Consequently, all GR500 Series capacitors

undergo ten temperature cycles between -65°C and

+125°C prior to the electrical testing which eliminates

those capacitors failing to withstand this extreme

change in environment.

2. Surge Current —

Each GR500 capacitor receives

10 cycles @ -55°C, + 85°C. Each cycle consists of rated

voltage charge for 4±1 seconds and a discharge for 4±1

seconds. Total DC resistance (excluding the test capac-

itor) is

≤1.0

ohms. The energy storage bank capacitor(s)

is 100,000 µF minimum.

3. Grading —

This term is used to describe the tech-

nique which defines the failure rate of KEMET Graded

Reliability capacitors. Grading consists of placing

GR500 capacitors in an oven at 85°C for a minimum of

250 hours at a voltage greater than rated voltage. The

technique is fundamentally based upon the oft-docu-

mented fact that solid tantalum capacitors do not con-

form to the exponential distribution of time-ordered fail-

ures, but instead exhibit a constantly decreasing failure

rate. The Weibull distribution provides a valuable tool

for describing the behavior of solid tantalum capacitors,

and experimental fits are made to this distribution in

determining performance levels for each GR500 Series

batch. Actual test data are provided with each shipment

of capacitors to document the failure rate obtained.

4. Electrical Testing —

Each GR500 Series capacitor

is tested at 25°C for leakage current at rated voltage, as

well as capacitance and dissipation factor at 120 Hz.

Since uniformity is generally a valid indicator of relia-

bility, parametric distributions are graphically recorded

for each lot. Parts which deviate from the normal popu-

lation are discarded. Guaranteed maximum values are

as detailed in Table 1.

5. ESR —

Each GR500 capacitor is tested for ESR @

100 KHz. See electrical specification tables.

6. X-ray —

Each GR500 Series capacitor is examined

by X-ray in two planes with 90 degree rotation. Since

assembly of the solid tantalum capacitor is a blind oper-

ation, optical inspection cannot reveal internal defects

such as loose solder balls or deficient anode solder

bonding.

7. Hermeticity —

Each GR500 capacitor receives her-

meticity testing per MIL-STD-202, Method 112,

Condition D. This test uses a fluorocarbon liquid at

125°C±5° (257°F± 9°F) at ambient pressure and detects

gross leaks by the observation of bubbles.

C. Sampling —

In addition to the 100% screening tests,

other tests are imposed on a sample basis to determine para-

metric stability and resistance to environmental extremes.

These tests are fully described in the GR500 Graded

Reliability Specification.

D. Available Special Testing —

In addition to the standard

testing outlined in this catalog, optional testing is available.

1. 100% ESR testing at various frequencies

2. 1 KHz DF

3. Tightened DC leakage, Capacitance and Dissipation

Factor limits.
