Power resistors take on transistor outlines

A wide range of TO-style power film resistors are designed for use in power electronic circuits such as snubbers, current limiting, loads, current sensing and other power resistor applications.

A wide range of TO-style power film resistors that are designed for use in power electronic circuits such as snubbers, current limiting, loads, current sensing and other power resistor applications, is available from Rhopoint 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 500MHz in the 25 to 100ohm range.

Values as low as 0.005ohm make them particularly suited for current sensing applications.

The resistance range of these resistors is from 0.005ohm to 100kohm and tolerances are standard at 1% for most resistance values, although 5% tolerances are available.

The resistors are produced in TO-126, TO-220 and TO-247 style packages: the TO-126 has power ratings up to 25W, the TO-220 up to 50W (TO-220 clip mount up to 60W) and the TO-247 up to 100W, all at +25C case temperature.

Many standard values are available from stock.
