| TOKEN RMG20 TO-220 Power Resistors TO-220 Power Resistors Power Resistors (TO-220 RMG20) Deliver Thermal Efficiency Preview Providing design engineers with superior heat dissipation in a standard industry-recognised package, Token Electronics has introduced a TO220-style power resistor using a highly reliable, economical copper thick film. The RMG20 Series, designed by Token, are rugged resistors feature noninductive performance and low thermal resistance, making them ideal for a variety of industrial applications such as power supplies, industrial controls and automotive, where cost effective performance and reliability are paramount. The non-noble copper ink construction of the RMG20 Series resistor makes it an efficient alternative to other thick film leaded power resistors while maintaining the excellent thermal conductivity and heat dissipation necessary for demanding power applications. With low resistance values at higher power ratings, Token's proprietary resistor element ensures design engineers the highest quality noninductive performance in an efficient package. Operating temperatures range from -65C to +150C. Constructed with proprietary thick-film copper conductors and alloy resistors on an alumina ceramic substrate, the RMG20 Series resistor features low thermal impedance for high power dissipation. Contact us with your specific needs. Features - Molded Case for Protection and Easy to Mount. - 20 Watt at 25C Case Temperature Heat Sink Mounted. - Isolated Case, Non Inductive, TO-220 Style Power Package. Applications - VHF Amplifiers, Snubber Circuits, Voltage Regulation, Load Resistor for Pulse Generators, High Speed Switching Power Supplies.
