INTRODUCTION
This series of power film resistors offers a high power handling capability in a compact, non-inductive format.
Both the TNP50S and the TNP100S are TO247 models handling 100W and 140W respectively, depending on
the ohmic value.  This entire range is constructed using high thermal conduction alloys resulting in excellent
heat transfer when  mounted on heatsinks.  Applications for these models include:  Gate and snubber
resistors in power supplies, load and dumping resistors in CRT monitors, terminal resistance in RF amplifiers,
power equipment, RF circuits, UPS, motor control, automated machine controls and power supplies.
