POWER RATING
Vishay RH resistor wattage ratings are based on mounting to the following heat sink: ?
RH005 and RH010: 4" x 6" x 2" x 0.040" thick aluminum chassis (129 sq. in. surface area) ?
RH025: 5" x 7" x 2" x 0.040" thick aluminum chassis (167 sq. in. surface area) ?
RH050: 12" x 12" x 0.059" thick aluminum panel (291 sq. in. surface area) ?
RH100 and RH250: 12" x 12" x 0.125" thick aluminum panel (294 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 = RH005 and RH010 size resistor, unmounted ?
B = RH025 size resistor, unmounted ?
C = RH050, RH100 and RH250 size resistor, unmounted ?
D = All types mounted to recommended aluminum heat sink ?
