IRC Debuts TO-220 TFP Series Power Resistors

The IRC Inc. Advanced Film Division of TT electronics plc (Patterson, NJ) introduced a TO220-style power resistor using a reliable, economical copper thick film. Designated the TFP Series, the rugged resistors feature non-inductive performance and low thermal resistance, making them suitable for a variety of industrial applications where cost-effective performance and reliability are paramount.

Typical applications for the TFP Series include power supplies, industrial controls, automotive and inrush/bleeder resistors. The TFP Series resistors offer resistance ranges from 0.010 Ohm to 1 kiloohm with tolerances to ±1 percent. The resistors are rated for 20W at 25 degrees C case temperatures and thermal resistance is 8.0 degrees C/W. Operating temperatures range from -55 to +150 degrees C. Constructed with proprietary thick-film copper conductors and alloy resistors on an alumina ceramic substrate, the TFP Series resistor features low thermal impedance for high power dissipation.
