Additional Details

The PR1101W-TR emits infrared light at a wavelength of approximately 940nm, which is a common wavelength for IR remote control systems. The narrow viewing angle concentrates the light beam, allowing for greater range and accuracy. The LED is designed for surface mount assembly, which simplifies the manufacturing process and reduces assembly costs. The device is also lead-free, making it compliant with environmental regulations. Typical forward voltage is around 1.2-1.6V, and forward current is dependent on the specific application requirements. The operating temperature range is generally between -40°C to +85°C.

It is often used in conjunction with an IR receiver, such as the Lite-On PR1003, to create a complete IR communication system. When selecting this IR LED, it's important to consider the specific radiant intensity, wavelength, and viewing angle requirements of the application to ensure optimal performance.
