This compact IR emitter is a light emitting diode designed to transmit infrared signals, such as those used in remote control and generic IR communication projects.
It operates at 940nm, making it suitable for common infrared receiver systems. Like any LED, it should be used with an appropriate current-limiting resistor and can be driven up to its rated forward current.
The LTE-302 is supplied as an individual through-hole, side-view component, making it easy to add to custom PCBs, prototypes, and maker projects.
Specifications:
- Current - DC Forward (If) (Max): 50mA
- Radiant Intensity (Ie) Min @ If: 0.662mW/sr @ 20mA
- Wavelength: 940nm
- Voltage - Forward (Vf) (Typ): 1.2V
- Viewing Angle: 40°
- Orientation: Side View
- Operating Temperature: -40°C ~ 85°C (TA)
- Mounting Type: Through Hole
A handy part for building or repairing IR transmitters, remote-control projects, and basic infrared signalling circuits.
Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- through-hole
- A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
