LSP1800AJR-S Bourns

Features Applications Fast switching LED streetlights Automatic reset LCD backlighting SMB package Display lighting Suitable for industrial lighting environments Intrinsically safe lighting RoHS compliant* LSPxxxxBJR Series LED Shunt Protector General Information Bourns LSP Series protectors are electronic shunts that provide a current bypass Anode when an LED element in an LED string fails open circuit. This ensures the remaining LSPxx00 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, Control avionics, intrinsically safe and low maintenance lighting. Circuit The LSP Series is available in surface mount package DO-214AA (SMB) size format.
