Pulse Energy Calculator Tool

Pulse Type:

Square Wave Pulse

A constant voltage or current is applied across a resistor for a given pulse duration.

Capacitive Charge/Discharge Pulse

A capacitor is charged to a given voltage and then discharged through a wirewound resistor.

Exponentially Decaying Pulse

The application reaches a peak voltage and decreases at a rate proportional to its value. This is typically modeled by DO-160E WF4 or IEC 61000-4-5 and represents a lightning surge.
