scope:
This specification covers the general requirements for established reliability (ER), general purpose, ceramic dielectric, insulated, fixed capacitors, for use in application where appreciable variations in capacitance with respect to temperature, voltage, frequency, and life can be tolerated(see 6.1). Capacitors covered by this specification have failure rate levels ranging from 1.0 to 0.001 percent per 1,000 hours. These failure rate levels are established at a 90-percent confidence level and maintained at a 10-percent producer's risk and based on life tests performed at maximum rated voltage at maximum rated temperature. An acceleration factor of 8:1 has been used to relate life test data obtained at 200 percent of rated voltage at maximum rated temperature, to rated voltage at rated temperature. 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.
Capacitors covered by this specification shall be classified, as specified (see 3.1).
intended Use:
These capacitors are primarily designed for use where a small physical size with comparatively large electrical capacitance and high insulation resistance is required. General purpose ceramic... View More
