HPDC resistor manufacturers | High Power Density Chip Resistor

This page mentions HPDC (High Power Density Chip) Resistor manufacturers or vendors. The popular manufacturers of HPDC resistor include TT electronics, Rohm Co., Ohmite Mfg. Co., Viking Tech Corporation, KOA Corporation etc.

What is HPDC resistor ?

The HPDC resistors are specially designed resistors which can be used for various applications which include power management, heating, actuator controls, motor drives, power amplifiers, power supplies etc.

These resistors use higher thermal conductivity compare to conventional chip resistors. They offer large area terminations to provide better thermal contacts on PCB surface.

The benefits or advantages of HPDC resistors are as follows.
➨It saves PCB area.
➨It boosts reliability.
➨It restricts temperature rise at areas of hotspots of components due to larger thermal contact.
➨It enhances heat transfer from element to terminal.
