About this product
A 3 mm infrared LED transmitter that emits light outside the visible spectrum. It is used as the emitter in remote controls, object detection and optical link circuits, where it is paired with a matching infrared receiver. Because it is a diode, observe its polarity and limit the forward current with a series resistor.

Frequently asked questions
What is the price of Infrared LED Transmitter 3mm (IRT LED) in Egypt?
Infrared LED Transmitter 3mm (IRT LED) currently costs 1.5 EGP in Egypt.
Where can I buy Infrared LED Transmitter 3mm (IRT LED) in Egypt?
Infrared LED Transmitter 3mm (IRT LED) is available from Microohm. Compare the offers above to find the best price.
Does the IR transmitter need a resistor?
Yes. A series resistor limits the forward current. Calculate it as R = (Vsupply - Vf) / I, using the forward voltage and current values from the LED's datasheet.
Which receiver should I use with this transmitter?
Use an infrared receiver whose wavelength and carrier frequency match the transmitter. Confirm compatibility in both datasheets before building the optical link.
