MIL-PRF-39007-12 Resistor, Fixed Wire-Wound \(Power Type\), Nonestablished Reliability, Established Reliability, And Space Level Style Rwr82This specification covers the associated requirements for style RWR82, nonestablished reliability, established reliability, and space level, power type, wire-wound, fixed, resistor. These resistors are available with terminal types "S" \(solderable, inductively wound\), "W" \(weldable, inductively wound\), "N" \(solderable, noninductively wound\), and "Z" \(weldable, noninductively wound\).

NOTES:

1. Dimensions are in inches.

2. Metric equivalents are given for general information only.

3. Dimension A is clean lead to clean lead.

4. Lead concentric tolerance is to be measured at the point of lead egress from the resistor body to be

within .016 TIR.

5. Lead length for tape and reel packaging shall be 1 inch minimum.
