Lens Color: Transparent Blue
Terminal Type: 2-Pin Through-Hole.
Emission: Infrared (IR) Spectrum.
Lead Material: High-Conductivity Tin-Plated Wire.
How do I know if the LED is working?
Infrared light is invisible to the human eye. To test if it is transmitting, point a digital camera or smartphone camera at the LED while it is powered; you will typically see a faint purple or white glow through the camera screen.
Which pin is positive?
Like standard LEDs, the longer lead is the Anode (positive), and the shorter lead is the Cathode (negative).
Do I need a resistor?
Yes! Always use an appropriate current-limiting resistor when connecting these LEDs to a power source to prevent overheating and ensure a long operating life.
