Electrical surges are a common failure mode for many types of resistors in a variety of harsh environments, including power supply, automotive and industrial applications. Thin film, solid composition ...

It’s an unfortunate fact that a resistor can fail under pulse loads. When pulse power is dissipated to the device’s resistive element, it generates heat and increases the resistor’s temperature.

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...

An array or bank of load resistors is often required for testing power products, characterization of solar panels, and many other applications that require evaluation under various well-defined loads.
