RPS 500
Vishay Sfernice Power Resistors for Mounting onto a Heatsink
Thick Film Technology
OVERLOADS
Short time overload: 2 Pn/10 s
Accidental overload: The values indicated in the graph below are applicable to resistors in air or mounted onto a heatsink.
POWER RATING CHART
The heatsink temperature should be maintained at the values specified in fig. 2.
To optimise the thermal conduction, contacting surfaces should be coated with silicone grease and heatsink mounting screws
tightened to 4 Nm.
