20 Pre-Wired 5mm Yellow LED Diode Lights Clear Round Lens 12V DC 680 Ohm Bulb Shape Size: B9 Looking for a pre-wired LED diode that is bright and includes a precisely matched resistor (±1% tolerance)? This unit is machine-soldered with 24AWG copper wires for a reliable connection, making it an excellent replacement for dashboard and control panel illumination. This single-color yellow LED emits light at a wavelength of 588-592nm (590nm/591nm). It provides a luminous intensity of 1500-2000 mcd with a 30-degree viewing angle, and is encased in a clear, transparent round 5mm lens. The operating voltage is 12V (compatible with 5V, 6V, 9V, and 12VDC systems, resulting in varying brightness levels). It draws a current of 20mA, has a power rating of 0.24W (0.25W), and features clear polarity: the Anode "+" (yellow wire) and the Cathode "-" (black wire). The LED comes with a pre-attached 24AWG tin-coated pigtail wire that is 7.9 inches (20cm) long. It is pre-soldered with a 680 Ω, 0.25W (1/4W) resistor that has a ±1% tolerance. The width of the resistor leg is 0.5mm. Suitable for a variety of uses, such as DIY lighting projects (illuminating keyboards, luminous toys, and cards), science circuit experiments, signal indicator lights, miniature component replacement, dollhouse lighting, and general electronics hobbies.
