These large ceramic cores are molded into an extruded aluminum, chassis-mount housing. The wirewound design maximizes pulse handling capability, while the aluminum housing provides for superior heat conduction and resistance to very tough environmental conditions.

Molding compounds must have excellent electrical properties and depending on their molding process can use a standard transfer mold compound or an injection mold epoxy.

Key Application Considerations:

  • High power resistors can handle up to 300W
  • Low tolerances and resistances from 0.1 Ohms to 100 kOhms
  • Used in industrial motor controls and drives

Key Material Properties:

  • Very high dielectric strength
  • Transfer- or injection-grade mold compounds
  • CTE-matched to the aluminum housings
MH20-01 Black Very tough, high operating temperature epoxy mold compound for power resistors, switches, fuses, actuators, and explosion proof housings 
MH20-01 is a very tough epoxy mold compound with excellent high temperature resistance. It is used in applications that use thermoset plastics instead of thermoplastics because of the high temperature requirements
MH20-01 Gold Very tough, high operating temperature epoxy mold compound for power resistors, switches, fuses, actuators, and explosion proof housings 
MH20-01 is a very tough epoxy mold compound with excellent high temperature resistance. It is used in applications that use thermoset plastics instead of thermoplastics because of the high temperature requirements.
MH20-0686 Black Epoxy Molding Compound 
MH20-0686 is a very tough epoxy mold compound with excellent high temperature resistance. It is used in applications that use thermoset plastics instead of thermoplastics because of the high temperature requirements.
