In this video Vishay Intertech introduces its Joule Wizard Pulse tools. The Pulse Energy Calculator helps determine the energy content of a waveform and components pulse load.
JouleWizard combines Vishay pulse tools into a single location that enables to determine the pulse energy of application waveform, parametrically searching for pulse capable products such as power metal strip resistors, wirewound resistors, shunt resistors or to Pulse capability curves. JouleWizard also combines links to useful resources that will help you to understand the dimensions that affect product pulse performance.
