THICK FILM POWER RESISTORS

TO-220 Thick Film Power Resistors

RMG35 W

Tokenchina's wide range of TO-style thick-film RMG35 resistors that are designed for use in power electronic circuits such as snubbers, current limiting, loads, current sensing and other power Supply applications. Their compact heatsink-mountable construction ensures that they are ideal for high-power-density applications, and the noninductive form.

The power RMG35 series is lead-free and RoHS compliant. Please contact our sales representative for more information.
