HDP SERIES
FEATURES
r Industry’s most economical TO-style power resistors!
r Standard resistance range: 0.05Ω to 10KΩ
r Standard tolerance: ±1%, ±2%, ±5% ( available to 0.1%)
r Flame resistant construction
r Non-Inductive performance
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.
r Resistor is electrically isolated from the mounting surface
OPTIONS
r Option EQ: 24-hour burn-in at full rated wattage (free air)
r Option 33: 1KV Dielectric Stength
r Numerous design modifications are available (special
marking, custom lead wires, hi-rel screening, etc).
Customized components are an RCD specialty!

POWER RATING
HDP220
-
1001 - F B
P/N DESIGNATION:
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.
