MIL-PRF-39003/4G
REQUIREMENTS:
Style CSR91 shall consist of two style CSR13 capacitors, from the same production lot, which have been subjected
to all group A testing for style CSR13 for exponential or Weibull distribution, as applicable. A Weibull graded
CSR91 shall consist of Weibull graded CSR13s and an exponential graded CSR91 shall consist of either
exponential or Weibull graded CSR13s. The failure rate level of the CSR13s shall be the same or lower than the
failure rate level of the CSR91.
Design and construction: In accordance with MIL-PRF-39003.
Dimensions and configuration: See figure 1.
Case type: Tubular, insulated.
Capacitance (nom): See table I.
Capacitance tolerance: ±10 or ±20 percent as shown in table I.
Failure rate level: See table I.
DC leakage: See table I.
Capacitance: In accordance with MIL-PRF-39003, except the maximum voltage applied during measurement shall
be 2.2 volts rms at 120 Hz at 25°C. If ac voltage is less than 0.5 volts, no dc bias is required.
Dissipation factor (DF): See table I.
Marking: In accordance with MIL-PRF-39003.
Part or Identifying Number (PIN): M39003/04-(dash number from table I).
Substitutability data:
Substitutability for failure rate levels shall be as follows: In accordance with MIL-PRF-39003.
