The 3mm Red DIP LED is a set of standard through-hole diffuse red light-emitting diodes designed for low-power visual indication and display applications.
The 3mm Red DIP LED is a set of standard through-hole diffuse red light-emitting diodes designed for low-power visual indication and display applications. Featuring a compact 3mm epoxy lens diameter and a bright, uniform red output (~620nm–630nm), these LEDs are ideal for space-constrained circuit layouts and breadboard prototyping.
These two-pin radial LEDs operate with a typical forward voltage of 1.8V to 2.2V DC and an optimal forward current of 10mA to 20mA (requiring a current-limiting resistor for safe operation). Their long positive anode lead and short negative cathode lead make polarity identification and assembly straightforward.
They are fully compatible with 3.3V and 5V microcontrollers like Arduino, ESP32, Raspberry Pi, PIC, AVR, breadboards, stripboards, and custom printed circuit boards (PCBs).
