TO247 Power Pulse-loading Resistors(RMG100)
100W High power resistor TO-247 RMG100Thumbnail Gallery
TO-247 Power Resistors handle high-speed pulses.
Providing design engineers with a high-power resistive device in a stable transistor style package, Token Electronics RMG100 Series TO-247 power resistors are available in 100W.
The resistors are specified for applications that require accuracy and stability. The RMG100 Series resistors are designed with an alumina ceramic layer that separates the resistance element and mounting tab.
This construction provides very low thermal resistance while ensuring high insulation resistance between the terminals and the metal back plate. As a result, the resistors feature a very low inductance, making them ideal for high frequency and high-speed pulse applications.
Additional applications for the RMG100 Series TO-247 resistors include automation test equipment, high frequency snubber and pulse handling circuits, motor control and drive circuits, switch mode power supplies, load resistors, automotive electronics, industrial power equipment, UPS systems and industrial computers.
RMG100 Series 100W resistors feature a resistance range of 0.1Ω to 10KΩ and operating temperature range is -65°C to +175°C.
Token will also produce devices outside these specifications to meet customer requirements. The RMG100 Series power resistors are RoHS-compliant with Pb-free Terminations. Contact us with your specific needs. Download PDF Specification TO247 Power Pulse-loading Resistors (RMG100).
