This yellow LED is designed for models, sign lighting, indicator lights, and other small projects. It has an output of 4,500mcd and a dominant wavelength of 588nm. The T1 through-hole 3mm LED has a clear lens and emits a 45° beam of illumination. It has a typical forward voltage of 2.2V at 20mA and a peak forward current of 100mA. Use of a resistor or other current-limiting device is crucial to prevent premature LED failure. Component LEDs are sensitive electronic devices and require some knowledge of electronic circuits to operate. Price listed is per unit; however, bulk discounts are available and are automatically applied to your order.

Important Notes - Please read before purchasing:
