ams OSRAM CHIPLED Series SFH 4043 940nm SMD Infrared Emitter Gainer LED

Product Description

The SFH 4043 is a compact surface-mount infrared emitter from ams OSRAM's established CHIPLED product line. Built for designs where board space is at a premium, this 0402-packaged IR LED delivers dependable 940nm output with fast switching speeds, making it a practical choice for high-volume electronics and sensing assembly.

Operating at 70mA forward current, the device produces a radiant intensity of 6 mW/sr, with rise and fall times of just 12ns to support high-speed infrared signaling and real-time sensing tasks. Its wide 140-degree viewing angle spreads infrared output evenly across the target area, reducing the number of emitters needed in broad-coverage designs.
