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

BLUE LIGHT WITH A CLEAR LENS - Each 3mm LED combines single-color blue output with a transparent round lens, helping makers add visual status indicators to control boards, signal circuits and custom electronics. ELECTRICAL VALUES FOR CIRCUIT MATCHING - Listed specifications are 3.0-3.2V forward voltage and 20mA operating current. Check these values against your design when selecting LEDs for a new circuit or replacing a matching component. COMPACT THROUGH-HOLE FORMAT - The 3mm round body and two leads support breadboard prototyping and PCB soldering, helping hobbyists test indicator layouts before assembling a permanent circuit. CHECK POLARITY AND CURRENT LIMITING - Verify the anode and cathode before wiring and use suitable current limiting. Forward voltage is not a direct power-supply rating; check the drive circuit before connecting to a supply or microcontroller output. 100 PIECES FOR REPEAT PROJECTS - This pack contains 100 blue LEDs in a resealable bag labeled with size, color and electrical values, helping students, hobbyists and repair users identify and store components between builds.
