Round Transparent LED 3mm 2Pin
Round Transparent LED 3mm 2Pin are compact, through-hole light-emitting diodes in color Blue and Red with two leads, widely employed in electronic indicators, displays, and lighting applications. These LEDs feature water-clear epoxy lenses that allow bright, focused light emission, with blue LEDs typically operating around 3.0–3.4V, emitting light at a wavelength near 470 nm and luminous intensities around 1000–2000 mcd. Red LEDs operate at lower forward voltages near 2.0V, emit wavelengths around 620–630 nm, and can achieve high brightness with intensities up to several thousand millicandela. All these LEDs maintain a polarity convention where the longer lead is the anode (positive), and the shorter lead is the cathode (negative), facilitating easy circuit integration. They are designed for reliable, low-power illumination with forward currents around 20mA and are suitable for various signaling and indication purposes, fitting snugly in compact electronic designs.
Features
- Compact 3mm diameter round shape with a water-clear epoxy lens for focused light emission.
- Two-pin through-hole design for easy PCB mounting and breadboard use.
- Polarity: Long lead is anode (+), short lead is cathode (–) for simple orientation.
- Forward voltage varies by color: Blue (~3.0-3.4V), Red (~1.6-2.0V).
- Forward current of approximately 20mA typical, with high reliability at low power.
- Bright luminous intensities: Blue around 1000-2000 mcd, Red up to several thousand mcd, Yellow around 3000-4500 mcd.
- Emission wavelengths approximately 470 nm (blue), 620-630 nm (red).
- Viewing angles around 18-36 degrees, adequate for indicator or signal applications.
- Operating temperature ranges typically -40°C to +85°C for durability.
- Suitable for indicators, displays, signaling, and general illumination in compact electronic projects.
- Stable and efficient LED performance with long life and consistent color output.
