LSPxxxxAJR Series LED Shunt Protector

General Information

Bourns® LSP Series protectors are electronic shunts that provide a current bypass

when an LED element in an LED series string fails open circuit. This ensures the

remaining string of LEDs will continue to function. There are many cases where high

reliability of the LED lighting must be maintained, such as LCD backlighting, transport

lighting, avionics, intrinsically safe and low maintenance lighting.

The LSPxxxAJR Series is available in surface mount package DO-214AC (SMA) size

format.
