IR-TRANSMITTER

An IR LED is a specially designed LED which transmits infrared rays. These rays are not able to be seen by the human eyes as it’s not in the range of human visible electromagnetic radiation spectrum. We can only see light rays from violet to red whose wavelength travels from 380 (violet light) to 750nm (red light). The IR LED is same aspect as the normal LED. IR LED stands for “Infrared Light Emitting Diode”, they allows to emit light with the wavelength of up to 940nm, which is the infrared range of electromagnetic radiation spectrum. The wavelength range varies from 760nm to 1mm. These are mostly use in the remote control of TV’s, cameras and different types of electronic instruments. The semiconductor material used to make these LEDs are gallium arsenide or aluminum arsenide. Mostly used in IR sensor as it is the combination of IR receiver and IR transmitter (IR LED). Technical Specifications Forward current (IF) is 100mA (normal condition) and 300mA (max.) 1.5A of surge forward current 1.24v to 1.4v of forward voltage Temperature for storage and operation varies from -40 to 100 ℃ Soldering Temperature should not exceed 260 ℃ Power Dissipation of 150mW at 25℃ (free air temperature) or below Spectral bandwidth of 45nm Viewing angle is 30 to 40 degree Features High Reliability Excessive radiant intensity Forward voltage is low Having lead spacing of 2.54mm Maximum wavelength is 940nm Pb free RoHS certified Easy to use with breadboard or perf board Package type is T-1 3/4 (B.5)
