Resistance to power pulse

Part numbering system

Test procedure

Voltage pulse is applied to the test samples mounted on the

test board.

After each pulse, resistance drift is measured. Pulse voltage

is increased until the drift exceeds +/-0.5%. The power at

that voltage is defined as the maximum pulse power.
