RCD Introduces Industry’s Highest Power ‘TO-220 Package’ Resistors

Manchester, New Hampshire (USA) – May 15, 2000 – RCD Components Inc., a leading manufacturer of resistors, coils, and delay lines has announced a breakthrough in high power density resistors. This unique design enables a greatly increased power rating, up to 2 to 3 times the typical wattage found in similar package sizes. For example the wattage rating of RCD’s new TO-220 size is 60-watts vs. 20-watts for typical industry package, making it especially suited for a diverse range of applications. Applications include power supplies, RF systems, power switching circuits, telecom line cards, medical instrumentation, and data transmission systems.

RCD’s new family, designated HDP (High Density Power resistor) features a newly developed proprietary filming process. The resistance film is deposited onto a steel carrier, and insulated with a hi-temp highly thermal conductive material enabling the highest power density in the industry. The terminal attachment and resistance element geometry is configured to provide outstanding non-inductive performance.

The HDP series is available in three common package sizes, including a TO-126 size (HDP126), TO-220 size (HDP220), TO-247 size (HDP247). Available in wattage ratings of 30-watts for HDP126, 60-watts for HDP220, and 120-watts for HDP247. Dimensions are .44″ long x .32″ wide x .079″ high (HDP126), and .64″ long x .41″ wide x .079″ high (HDP220), and .818″ long x .62″ wide x .079″ high (HDP247), and available in a wide resistance range from 0.05W to 10KW, 1% to 5% tolerance. Samples and production quantities of RCD’s HDP series are available now, with lead-times of six to eight weeks for larger orders. Typical pricing is less than $1.60 each at the 1000 piece level.
