POWER RATING
Vishay TMC resistor wattage ratings are based on mounting to the following heat sink:
TMC005 and TMC010: 4" x 6" x 2" x 0.040" thick aluminum chassis (129 sq. in. surface area)
TMC025:
5" x 7" x 2" x 0.040" thick aluminum chassis (167 sq. in. surface area)
TMC050:
12" x 12" x 0.059" thick aluminum panel (291 sq. in. surface area)
TMC100 and TMC250: 12" x 12" x 0.125" thick aluminum panel (294 sq. in. surface area)
