TO-220 snubber Power Film bleeder resistors (RMG30)

TO-220 Power Resistors take on transistor outlines.

A wide range of TO-style power film resistors that are designed for use in power electronic circuits such as snubbers, current limiting, bleeder, current sensing and other power resistor applications, is available from Direct Components.

Their compact heatsink-mountable construction ensures that they are ideal for high-power-density applications, and the noninductive form allows these TO-style resistors to operate at up to 30 Watt at 25°C case temperature.

RMG30 Series values as low as 0.05Ω make them particularly suited for current sensing applications with Pb-free Terminations Meet RoHS Requirments.

The resistance range of these resistors is from 0.05Ω to 10KΩ and tolerances are standard at 1% for most resistance values, although 5% tolerances are available.

Many standard values are available from Direct. Contact us with your specific needs. Download PDF Specification TO-220 bleeder Power Film snubber resistors (RMG30).
