MIL-HDBK-217 RESISTOR TABLES

If you need MTBF calculation for resistors, click here.

This section includes the various tables for resistor specifications: Resistor types, temperature factor, power factor, power stress factor, environment factor, and quality factor. Included are both active and some older/inactive specifications because of the large number of equipments still in field use which contain these parts.
