CAPACITORS, FIXED, PLASTIC (OR METALLIZED PLASTIC) DIELECTRIC, DC OR DC-AC, IN NONMETAL CASES, NON-ESTABLISHED AND ESTABLISHED RELIABILITY GENERAL SPECIFICATION FOR
Organization:
ARMY - CR - US Army Communications Electronics Command
Year: 2005
Abstract: This specification covers the general requirements for established reliability (ER) and non-established reliability (non-ER), (product level C), plastic (or metallized plastic) dielectric, fixed capacitors, enclosed in nonmetal cases intended primarily, in view of the limited long term moisture resistant characteristics, for use in potted or encapsulated systems, in blocking, filter, and by-pass applications (see 6.4). ER capacitors covered by this specification have failure rate levels (M, P, R, and S) ranging from 1.0 percent to 0.001 percent per 1,000 hours. These failure rates (FR) are established at a 90-percent confidence level and maintained at a 10-percent producer's risk and based on life tests performed at +85°C or +105°C, whichever is applicable. An acceleration factor of 5:1 has been used to relate life test data obtained at 125 percent, or 140 percent of rated voltage at +85°C or +105°C, whichever is applicable, to rated voltage at +85°C or +105°C, whichever is applicable. The product levels are based on catastrophic failures and failures occurring outside the degradation limits.Intended Use: These capacitors are intended to be used in potted or encapsulated systems, in blocking, filter, and by-pass applications (see 6.4). Capacitors covered by this specification are unique due to the fact that these devices must be able to operate satisfactorily in military systems under the following demanding conditions: 20 Gs of high frequency vibration, 100 Gs of shock (specified pulse), and operate in extreme temperatures (-55°C and up to +125°C). These capacitors also offer high reliability that is verified under a qualification system. Commercial components are not designed to withstand these military environmental conditions.
