IR transmitter Green Cell EB279798306# 5 mm 950 nm infrared LED

Green Cell IR transmitter EB279798306# is a 5 mm infrared LED that emits at a wavelength of 950 nm. It is supplied in a compact through-hole package suitable for PCB mounting. The emitter produces focused infrared output intended for short- to mid-range transmission in remote controls, IR communication links and sensing circuits. Its physical size and optical beam characteristics simplify integration into consumer electronics modules and hobbyist projects.

Advantages

The 5 mm package offers simple mechanical mounting and reliable soldering to standard printed circuit boards. Emission at 950 nm provides compatibility with most IR receivers and photodiodes used in remote-control systems and proximity sensing. The component delivers concentrated output for efficient signal coupling, with stable performance under typical operating currents. Its compact form factor makes it suitable for confined enclosures and custom housings without requiring specialized mounting hardware.

How to use

Install the LED into the PCB through the designated holes, observing correct polarity. Use a suitable current-limiting resistor or a constant-current driver to set the operating current within the manufacturer's recommended range for the 5 mm IR emitter. For remote-control and communication applications, align the emitter toward the receiver to optimize signal coupling and minimize obstructions. Ensure adequate solder joints and verify thermal conditions when operating at higher duty cycles or ambient temperatures.

Usage recommendations

For reliable operation, select a current-limiting resistor or driver that prevents overcurrent and ensures the LED’s forward current stays within safe limits. When designing enclosures, provide an unobstructed optical path and consider small lenses or apertures to shape the beam if needed. Store unused components in anti-static packaging and avoid prolonged exposure to temperatures or humidity outside normal electronic component storage ranges.
