LPS 300
Power Resistor for Mounting onto a Heatsink
Thick Film Technology
Vishay Sfernice
OVERLOADS
In any case the applied voltage must be lower than U
L
= 5000 V.
Short time overload: 4 x P
n
/10 s
Accidental overload: The values indicated on the following
graph are applicable to resistors in air or mounted onto a
heatsink.
ENERGY CURVE
POWER RATING
The temperature of the case should be maintained within the
limits specified in the following figure.
To optimize the thermal conduction, contacting surfaces
should be coated with silicone grease or thermal film, and
heatsink mounting screws tightened to 2 Nm.
MARKING
Series, style, ohmic value (in Ω), tolerance (in %),
