Numerous design modifications are available (special
marking, custom lead wires, hi-rel screening, etc).
Customized components are an RCD specialty!
Award winning design! High power density at low prices!
RCD Series HDP resistors were designed to offer precision
performance in TO-126, TO-220 and TO-247 style packages.
The cost effective design features an oxidized stainless steel
carrier which is insulated with a proprietary hi-temp dielectric
upon which the resistive film and solder pads are deposited.
This enables reduced thermal resistance over conventional
ceramic or ceramic/copper sandwich designs, resulting in
increased power and overload capability (pulse graph avail-
able). The resistive film is insulated with a specialty flame
resistant coating offering superior environmental protection.

POWER RATING
Power rating is based on the resistor being tightly screwed to a suitable
heat sink (with thermal compound) to limit hot spot case temperature to
200°C. Derate wattage by .57%/°C above 25°C (as depicted in chart
below). Mounting torque not to exceed 8 in-lbs. Request Applic.Guide R-
34 for additional information concerning heat-sink resistor mounting
guidelines.
