MPM20 Kool-Tab Power Film Resistors introduce a "Pure Tin Free" design for High Performance Applications. Our proven Micronox resistance film system is utilized in the widely accepted TO-220 Power Package to provide a compact 20 watt heat sink mountable resistor. The non-inductive design makes this resistor ideal in high frequency communications, power switching circuits and snubbers. The special performance features of the series MPM20 Kool-Tab Power Film Resistors include: Up to 20 Watt power rating at +25°C case temperature. Resistance values as low as 0.020 ohm for current sense applications. Non-Inductive Design. Single screw mounting simplifies resistor attachment to the heat sink. Low profile provides an easier fit in tight places. A molded case for environmental protection. Resistor element is electrically isolated from the metal heat sink tab.
