The Red LED 5mm is a set of standard through-hole red light-emitting diodes engineered for clear, low-power visual signaling and circuit state indication. Featuring a classic 5mm epoxy lens diameter with a diffuse/clear red output (~620nm–630nm), these LEDs provide high visibility and uniform light distribution for control panels, breadboards, and custom electronic enclosures.
These 2-pin radial leaded LEDs operate at a typical forward voltage of 1.8V to 2.2V DC and a nominal forward current of 15mA to 20mA (always use a current-limiting resistor for safe operation). Polarity identification is quick and easy with a longer positive anode lead and a shorter negative cathode lead.
They are fully compatible with 3.3V and 5V microcontrollers including Arduino, ESP32, Raspberry Pi, PIC, AVR, breadboards, stripboards, and custom printed circuit boards (PCBs).
