High Performance Molded Heat-Sink Resistors
OPTIONS
RCD’s MP series feature power film resistor elements designed
for excellent environmental stability as well as superior high-
frequency performance (custom designs up to 1GHz avail.). All
sizes feature metal base plate for optimum heat transfer. The
resistor is electrically isolated from the metal tab, and molded into
various package styles with high-temp flame-retardant epoxy.
MP126 and MP220 in reduced wattage ratings now available
in tighter TCs and tolerances from 10Ω to 49.9K: MP126 (5W)
to 0.025% and 2ppm, MP220 (10W) to 0.05% and 5ppm.
Option P: Increased pulse capability
Option G: Gull-wing lead formation for surface mounting
Option B: Increased power design
Numerous design modifications are available (special
marking, custom lead wires, burn-in, etc).

POWER RATING
RCD Type
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 155°C.
Derate W, V, A by .77%/°C above 25°C (as depicted in chart below). Mount-
ing torque not to exceed 8 in-lbs. Refer to Applic.Guide R-34 for additional
detail concerning heat-sink resistor mounting guidelines.
