(1) Lead length for product in bulk pack. For product supplied in
tape and reel, the actual lead length would be based on the body
size, tape spacing and lead trim.

Surface temperatures were taken with an infrared pyrometer in
+ 25 °C still air. Resistors were supported by their leads in test
clips at a point 0.500" (12.70 mm) out from the resistor body ends.
