5-Colour 300-Pc LED Diode Kit

A complete 300-piece collection of standard through-hole LED diodes in red, yellow, blue, green and white. All units feature epoxy resin encapsulation for mechanical durability and environmental resistance. Available in two industry-standard physical sizes — 3mm and 5mm — ensuring compatibility with most educational kits, breadboards and commercial PCB footprints. Electrical characteristics are tightly controlled: 20mA nominal forward current, with forward voltage ranges grouped by colour family (2.0–2.2V for red/yellow; 3.0–3.2V for blue/green/white). These diodes support fundamental circuit functions including current rectification and minor stabilisation roles, while delivering pure visible-light output free of ultraviolet or infrared emissions. Widely applicable in UK-based electronics education, hobbyist prototyping, and functional upgrades for domestic electronics and instrumentation panels.
