low-Profile Power TO220 Non-Inductance Resistors (RMG50)

Providing design engineers with an open screened substrate device for applications requiring superior thermal performance, Token Electronics has developed a non-moulded power resistor rated up to 50W.

Designated the RMG50 Series, the resistor is housed in a TO-220 opened screened substrate package, and features an insulated tapered venturi bonded to the substrate for maximum heat dissipation. The design of the RMG50 Series resistor allows for three methods of heat dissipation, resulting in exceptional power handling characteristics.

The chimney-shaped tapered venturi is attached to the ceramic substrate and convection forces hot air up the 'neck' of the chimney and away from the resistor face of the component.

The power resistor utilises all three methods of heat dissipation, including conduction through the heatsink tab, radiation from the resistor surface, and convection through the venturi element. Typical applications for the RMG50 resistor include higher wattage switch-mode power supply circuits, motor control and drive circuits, inverters and industrial power equipment.

Resistance ranges from 0.05Ω to 10KΩ, with tolerances of ±0.50% and ±10% and operating temperature range is -65°C to +150°C. The RMG50 Series TO-220 provides customers requiring more wattage in a smaller package with an excellent alternative.

Token Electronics will also produce devices outside these specifications to meet customer requirements, with comprehensive application engineering and design support available for customers worldwide. Contact us with your specific needs. Download PDF Specification Low Profile TO220 Resistor (RMG50).
