MIL-PRF-55342 is the military performance specification for surface mount and wire bondable, fixed film chip resistors.

MIL-PRF-32159 is the military performance specification for surface mount and wire bondable zero ohm resistors.

MIL-PRF-55342 resistors and MIL-PRF-55342 zero ohm resistors are used in mission critical avionic, satellite, space, biomedical, and military applications.

State of the Art, Inc. offers all thirteen case sizes (slash sheets) included in MIL-PRF-55342. MIL-PRF-55342 includes two screening levels: established reliability failure rate level maintained on the basis of life testing, and space level T which includes 100% power conditioning and a full Group B.

Product levels M, P, R, S, U, & V are established reliability (ER) failure rate product. ER products are subject to Group A, B, & C testing. Group A is performed on a manufacturing lot basis. Group B is performed on an inspection lot basis for ER levels M, P, R, & S and on a production lot basis for ER levels U & V. Group C is performed on an inspection lot basis for all ER levels.

Military Testing
Group A Inspection
  • Precap Visual Inspection
  • 100% Thermal Shock
  • 100% Power Conditioning      (T level only)
  • 100% D.C. Resistance
  • 100% Visual (T level only)
  • Visual Inspection
  • Solderability
  • Resistance to Solvents     (marked parts)

  • Group B Inspection
  • Resistance Temperature     Characteristic
  • Short Time Overload
  • Mounting Integrity

  • Group C Inspection
  • Life Test
  • Thermal Shock
  • Low Temperature Operation
  • Resistance to Soldering Heat
  • Moisture Resistance
  • High Temperature Exposure
  • Product level T is a space level resistor that includes power conditioning (burn-in) on a 100% basis as part of Group A to identify and screen any infant mortality defects from the manufacturing lot. Group B is performed on a production lot basis and Group C is performed on an inspection lot basis for product level T.
