Vishay RH resistor wattage ratings are based on mounting to the following heat sink:
RH-5 and RH-10:
RH-25:
RH-50:
4" x 6" x 2" x 0.040" thick aluminum chassis (129 sq. in. surface area)
5" x 7" x 2" x 0.040" thick aluminum chassis (167 sq. in. surface area)
12" x 12" x 0.059" thick aluminum panel (291 sq. in. surface area)

AMBIENT TEMPERATURE DERATING
Derating is required for ambient temperatures above 25°C, see the following graph.
Curves A, B, C apply to operation of unmounted resistors. Curve D applies to all types when mounted to specified heat sink.
A = RH-5 and RH-10 size resistor, unmounted
B = RH-25 size resistor, unmounted
C = RH-50, RH-100 and RH-250 size resistor, unmounted
