PERFORMANCE SPECIFICATION

CAPACITOR, FIXED, METALLIZED PLASTIC FILM DIELECTRIC,

(DC, AC, OR DC AND AC), HERMETICALLY SEALED IN METAL CASES OR CERAMIC CASES,

ESTABLISHED RELIABILITY, GENERAL SPECIFICATION FOR

This specification is approved for use by all Departments

and Agencies of the Department of Defense.

1. SCOPE

1.1 Scope. This specification covers the general requirements for established reliability (ER), metallized plastic

film dielectric, fixed capacitors, hermetically sealed in metal or ceramic cases. Capacitors covered by this

specification have failure rate levels (FRL) established in accordance with

MIL-STD-690.

The reliability for each level

is identified by a symbol in accordance with

table I.

These FRLs are established at a 90 percent confidence level and

maintained at a 10 percent producer's risk and, unless otherwise specified (see

3.1),

are based on life tests

performed at maximum rated voltage at maximum rated temperature. Unless otherwise specified (see

3.1),

acceleration factor of 5:1 has been used to relate life-test data obtained at 140 percent of rated voltage at maximum

rated temperature, to rated voltage at maximum rated temperature (see

6.1).

A part per million (PPM) quality system

is used for documenting and reporting the average outgoing quality of capacitors supplied to this specification.

Statistical process control (SPC) techniques are required in the manufacturing process to minimize variation in

production of capacitors supplied to the requirements of this specification.

1.2 Classification. Capacitors covered by this specification are classified by the style, as specified (see

3.1).

1.2.1 Part or Identifying Number (PIN). Capacitors specified herein (see

3.1)

are identified by a PIN which

consists of the basic number of the performance specification and a series of coded characters. The coded

characters provide information concerning the capacitors temperature coefficient, specification sheet number,

capacitance value, capacitance tolerance, voltage, case code, termination finish, and failure rate level. The PIN is in

the following form:

3.3 QPL system. The manufacturer shall establish and maintain a QPL system for parts covered by this

specification. Requirements for this system are specified in

MIL-STD-690

and

MIL-STD-790.

In addition, the

manufacturer shall establish a Statistical Process Control (SPC) and Part Per Million (PPM) system which meets the

requirements of 3.3.1 and 3.3.2, respectively. The following

MIL-STD-790

exception is allowed:

a. Under "Description of production processes and controls", the procedure for identification of each production

lot shall include only "the manufacturer shall as a minimum be able to identify the time period during which

the final production operation was performed on each item of product prior to final test. The date or lot code

marked on each part shall be identified to a production lot."

b. "Traceability" of materials shall not apply.

3.3.1 SPC system. As part of the overall

MIL-STD-790

QPL system, the manufacturer shall establish a SPC

system which meets the requirements of

JEDEC EIA-557.

Typical manufacturing processes for application of a SPC

include pre-assembly, assembly, encapsulation, and packaging.

3.3.2 PPM system. As part of the overall

MIL-STD-790

QPL system, the manufacturer shall establish a PPM

system for assessing the average outgoing quality of lots in accordance with

SAE EIA-554-1.

Data exclusion, in

accordance with

SAE EIA-554-1,

may be used with approval of the qualifying activity. The PPM system shall identify

the PPM rate at the end of each month and shall be based on a six month moving average.

3.4 Material. The material shall be as specified herein. However, when a definite material is not specified, a

material shall be used which will enable the capacitors to meet the performance requirements of this specification.

Acceptance or approval of any constituent material shall not be construed as a guaranty of the acceptance of the

finished product.

3.4.1 Impregnant. The impregnant shall be chemically inactive with respect to the capacitor element and the case.

The impregnant, either in the state of original application or as a result of having aged, shall have no adverse effect

on the performance of the capacitor. For liquid-impregnated capacitors, the same material shall be used for

impregnating as is used for filling.

3.4.2 Metals. Metals shall be of a corrosion-resistant type or shall be plated or treated to resist corrosion. Silver

plating shall not be used in any external portions of these capacitors.

3.4.2.1 Dissimilar metals. Where dissimilar metals are used in intimate contact with each other, provision shall be

made to provide protection against electrolysis and corrosion. The use of dissimilar metals in contact, which may

tend toward active electrolytic corrosion (particularly brass, copper, or steel used in contact with aluminum or

aluminum alloy), shall not be acceptable. However, metal plating or metal spraying of dissimilar metals to base

metals to provide similar or suitable abutting surfaces will be permitted (for example, the spraying of copper on

aluminum for soldering operations will be permitted). The use of dissimilar metals separated by insulating material

will also be permitted.

3.4.3 Pure tin. The use of pure tin, as an underplate or final finish, is prohibited both internally and externally. Tin

content of capacitor components and solder shall not exceed 97 percent, by mass. Tin shall be alloyed with a

minimum of 3 percent lead, by mass (see

6.7).

Lead-free, tin alloy high temperature solders may be used where high

temperature solder is necessary with the approval of the qualifying activity. The tin content of lead-free high

temperature solders shall not exceed 97 percent, by mass.

3.5 Interface and physical dimension requirements. Capacitors shall meet the interface and physical dimensions

specified (see

3.1).

3.5.1 Case. Each capacitor shall be enclosed in a hermetically-sealed case (see

3.1)

which will protect the

capacitor element from moisture, impregnant or filling compound leakage, and mechanical damage under all test

conditions specified herein.
