tape and reel, the actual lead length would be based on the body

size, tape spacing and lead trim.

Note

• 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.
