TO-220 THICK FILM RESISTORS

Precision TO-220 Thick Film Resistors

RMG50 W

Tokenchina's precision thick-film RMG50 is rated for 50W power dissipation and utilises all three methods of heat dissipation, including conduction through the heatsink tab, radiation from the resistor surface, and convection through the venturi element.

These RMG50 resistors feature a very low inductance, making them ideal for high frequency and high-speed pulse applications for use in high frequency industrial RF power sources, RF linear amplifiers, termination resistor of RF circuit etc.

The power RMG50 series is lead-free and RoHS compliant. Please contact our sales representative for more information.
