Rectangular Blue LED TH 2x3x4mm 467-472nm

From the shop's description

Rectangular Blue LED TH 2x3x4mm 467-472nm The rectangular blue LED in a 2 × 3 × 4 mm through-hole package offers a compact, flat-profile emitter that fits into narrow form-factors where a standard round LED might protrude too far. Its rectangular geometry gives a visually clean edge-look, making it suitable for indicator light bars, user-panels, or discrete status points where a subtle yet bright blue illumination is desired. The blue emission, in the ~467 to 472 nm region, produces a crisp, cool-tone indicator light that stands out against darker surfaces or equipment housings. Internally, the LED uses a GaN-based die tuned for blue output in that wavelength band. Its encapsulation in a rectangular, water-clear or diffused lens allows light to spread evenly across the flat face of the device, giving a consistent appearance rather than a pinpoint glow. With the small footprint and shallow height, the component integrates well into modern electronics assemblies, especially those needing low-profile indication elements. Mechanically and electrically the LED is built for durability and ease of use: standard TH leads for soldering, moderate forward voltage and current drive, and typical indicator-LED reliability. Its form factor supports both horizontal and vertical mounting scenarios, and the blue colour provides a distinct visual cue for status, power, activity or warning signals. Overall, this rectangular blue LED serves as a sleek, high-visibility signal source in compact electronics assemblies. Features: Compact 2 × 3 × 4 mm rectangular TH package. Bright blue emission in the ~465-470 nm (or near 467-472 nm) wavelength region. Uniform light distribution from flat rectangular lens shape. Low profile mounting suitable for tight assemblies and panel indicators. Through-hole lead configuration for simple soldering and board mounting. Suitable for high density indicator arrays where uniform visual appearance is important.
