WebOur PolySwitch radial-leaded PTCs devices provide engineers design flexibility and voltage ratings up to 240V allowing use in electronic and computer applications. Webfuse blowup during inrush current events. In addition, once the fuse blows during an overload event, it has to be physically replaced, which increases system down time and maintenance costs. On the other hand, PTC resistors provide resettable overcurrent protection and, unlike a fuse, these can avoid the physical intervention.
