Standard tolerance: ±1%, ±2%, ±5% ( available to 0.1%)
Flame resistant construction
Non-Inductive performance
Resistor is electrically isolated from the mounting surface
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 capability. The resistive film is insulated with a
specialty flame resistant coating offering superior environmental
protection. HDP Series is suitable for a wide range of applications.

POWER RATING
Power rating is based on the resistor being tightly screwed to a suitable
heat sink (with thermal compound) to limit 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.
