Bourns LSP Series protectors, like the LSP0900AJR-S, are electronic shunts that offer 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, maintaining high reliability in critical lighting applications such as LCD backlighting, transport lighting, avionics, intrinsically safe lighting, and low-maintenance environments. The LSP0900AJR-S is available in a surface mount SMA (DO-214AC) package and is RoHS compliant, making it a reliable and environmentally conscious choice for LED lighting systems. Proper power supply architecture is crucial for optimal performance.
