Additional Details

The PR1102W-TR IR LED operates at a typical wavelength of 940nm, commonly used in many IR applications. Its narrow viewing angle provides a concentrated beam of light, enhancing its performance in applications requiring precise targeting. It is designed for reflow soldering and is RoHS compliant. Specific electrical characteristics such as forward voltage and current depend on the operating conditions and application requirements. Typical operating temperature ranges from -40°C to +85°C. Designers should consult the datasheet for detailed specifications to optimize performance and ensure proper operation within specified limits.

This IR LED is often paired with an appropriate IR receiver, such as those from Lite-On or other manufacturers, to create a complete communication system. Considerations for the selection of the receiver should include wavelength sensitivity, response time, and ambient light rejection capabilities to match the characteristics of the PR1102W-TR.
