1206 Infrared Emitter An 850nm/940nm infrared emitter with a forward voltage of 1.1~1.6V depending on part number. Used for infrared remote-control transmission, security illumination and through-beam sensing, with optional 38kHz carrier modulation. Factory-direct from Dongguan Hongcheng Optoelectronics Co., Ltd. (an international member of Guangyu Group with over 20 years of LED packaging experience), it uses Grade A chips and 99.99% pure gold wire bonding and is RoHS certified. Free samples and custom wavelength, angle and power binning are available. Download the datasheet PDF on this page for complete electrical parameters and mounting dimensions.
Q: How should I choose between 850nm and 940nm infrared LEDs?
A: Choose 850nm for camera illumination (high sensitivity and long range), or 940nm for covert surveillance and sensing (no visible red glow). Radiant-power binning and pairing are available.
Q: What placement-machine accuracy does this LED require?
A: This product uses a 1206 package (3.2×1.6mm) with relatively large pads. Standard high-speed placement machines are adequate, with no special equipment accuracy requirements. Supports lead-free reflow soldering (peak ≤260℃/≤3s).
