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.
