Indoor LED Lighting Circuit Protection

Littelfuse Indoor LED Lighting Circuit Protection ensures a long operating life, increased energy efficiency, and safety. LEDs can be damaged by voltage or current surges, and by extreme temperatures. Littelfuse circuit protection technology protects LED assemblies from potential damage. Important circuit protection technologies include metal-oxide varistors (MOVs), transient voltage suppression (TVS) diodes, and fuses.

PolySwitch Resettable Devices

Littelfuse PolySwitch and POLY-FUSE Devices are Polymeric Positive Temperature Coefficient (PPTC) devices that offer a resettable overcurrent protection alternative, reducing warranty, service, and repair costs. PTCs increase resistance as temperature increases due to increased flow. The components are designed to limit unsafe currents while allowing constant safe current levels, resistance will "reset" automatically when the fault is removed, and temperature returns to safe levels. The ability of the PTCs to reset themselves after exposure to a fault current makes them ideal within circuits that are not easily accessible. PTCs are typically used as circuit protection in applications where sensitive components are at constant risk of damage from overcurrent conditions. The components are also ideal for situations where frequent overcurrent conditions occur or constant uptime is required. Littelfuse Resettable PTCs (PPTCs) are typically used in consumer electronics, power line, telecom, I/O port, process control and medical equipment protection applications.

PolySwitch Bladed Automotive Resettable PTC Fuses

Littelfuse BD280 and BD540 PolySwitch Automotive High-Temperature Bladed PPTCs provide resettable overcurrent protection for passenger vehicles and heavy truck wire harnesses. The PolySwitch bladed contact devices feature a 2.8mm and 5.4mm form factor to facilitate easy, one-to-one replacement of mini-sized fuses and Type II bimetal circuit protection devices in 12V vehicle systems. The devices help to reduce the weight of wire harnesses. PPTC devices distributed in a circuit can allow the use of smaller wire sizes with the resulting harnesses. Users can forego looping back and forth around a fuse box and place the protection where needed. The solid-state composition of the PPTC devices helps provide reliability.
