These high-power low resistance chip resistors are designed to dissipate heat efficiently
through the land patterns on circuit boards. The actual temperature of the surface of
the resistor is dependent upon the dimensions and the shape of the land patterns.

Test procedure
Voltage pulse is applied to the test
samples mounted on the test board.
After each pulse, resistance drift
i s m e a s u re d . P u l s e v o l t a g e i s
increased until the drift exceeds
+/-0.5%. The power at that voltage
is defined as the maximum pulse
power.
