MPM20 Kool-Tab Power Film Resistors Pure Tin Free design for High Performance Industrial and Military Applications TO-220 Style Power Package with Metal Mounting Tab 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 +25C 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. Use your thermal design experience with power semiconductors in TO-220 style power packages. This experience will help you get the most out of this unique family of power resistors. The thermal design issues are the same where power handling capability is based on the case temperature which is maintained in your design. Thermal Resistance Resistance Power Max. Model Dielect.
