OWOFYDR 100 3mm Red LED diode lamp (Transparent Lens Round DC 3V 20mA) Lighting Bulb Electronic Component Indicator Light Emitting

RED LIGHT THROUGH A CLEAR ROUND LENS - Each 3mm LED provides single-color red output through a transparent lens, helping electronics hobbyists add visual status indication to compatible control boards, signal circuits and DIY projects. LISTED ELECTRICAL AND OPTICAL VALUES - Specifications show 2.0-2.2V forward voltage, 20mA operating current and a 620-625nm wavelength range, helping users compare the component with circuit and color requirements. COMPACT 3MM THROUGH-HOLE FORMAT - The round body and two leads support breadboard prototyping and PCB soldering, helping makers test small indicator layouts before assembling a permanent circuit. CHECK POLARITY AND CURRENT LIMITING - Identify the anode and cathode before wiring and use suitable current limiting. Forward voltage is not a direct power-supply rating; check driver and microcontroller output limits before connecting power. 100 PIECES IN A LABELED RESEALABLE BAG - This pack contains 100 red LEDs in a bag marked with the size, color and electrical values, helping students, hobbyists and repair users identify and store components between projects.
