Circuit protection devices help ensure operational reliability

Bourns manufactures and supplies various circuit protection technologies, comprising fuses, PTC thermistors, varistors, resettable thermal cut-offs, GDTs, hybrid protectors, surge protection devices, discrete semiconductor solutions, and more, all available now from Mouser.

Reliable surge protection is a vital design consideration to assist operational reliability of consumer electronics, automotive, battery charging, industrial/communication equipment, energy storage infrastructure, and renewable energy harvesting ecosystems.

Power surges may cause damage to sensitive or exposed equipment and result in operational disruption, equipment degradation, and system downtime or destruction – not to mention safety hazards. The preferred form of protecting people and equipment against power surges is to block the excess voltage. This tactic needs applying surge suppression at the point in a circuit that protects all downstream devices and equipment, incorporating overall building surge suppression, including surge suppression into the devices and equipment themselves, or both.

Ensuring the correct surge protection components from Bourns are chosen for a given application, various elements must be determined: maximum continuous operating voltage, maximum reverse working voltage, peak current, peak power, and clamping voltage.
