XL-1005SURC-F is a "Right angle" ultra high brightness red LED developed by Chengxingguang on the 1005 (0402) packaging platform. By using a special light cup structure to horizontally export light from the side of the package, lateral light intensity is achieved within a board area of 1.0 mm × 0.5 mm × 0.4 mm. It is designed specifically for scenarios such as ultra-thin frames, side light guides, and hidden indicator lights that require dual strictness of "thickness limit+side light guide".
