Additional Details

The HIR26-21C/L289/CT typically operates with a forward voltage of around 1.2-1.5V and a forward current of around 100mA. Radiant intensity is a key parameter and is usually specified in mW/sr (milliwatts per steradian). The narrow viewing angle helps to concentrate the emitted light. The device's operating temperature range is typically from -25°C to +85°C. This device is ROHS compliant. Refer to the Everlight datasheet for precise electrical and optical characteristics, including forward voltage vs. forward current curves, radiant intensity vs. forward current curves, and spectral emission characteristics. Correct resistor selection is essential for limiting the forward current and preventing damage to the LED.
