MIL-PRF-39007-5 Resistor, Fixed, Wire-Wound\(Power Type\), Nonestablished, Reliability, Established Reliability, And Space Level Style Rwr71This specification covers the associated requirements for style RWR71, 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.
