LED Assortment Diffused 3mm General Purpose — 20-Pack (Mixed Colors)

LED Assortment Diffused 3mm General Purpose — 20-Pack (Mixed Colors)

A 20-pack of diffused 3mm general-purpose LEDs in mixed colors — the compact alternative to 5mm LEDs for space-constrained PCBs and tight enclosures. Includes red, green, blue, yellow, and white LEDs. The smaller 3mm package fits in tighter spaces and panel-mount holes while providing the same wide-angle diffused light distribution as 5mm LEDs.

Kit Contents

• Red LEDs — ~620–630nm, Vf ~2.0V
• Green LEDs — ~520–530nm, Vf ~2.1V
• Blue LEDs — ~460–470nm, Vf ~3.2V
• Yellow LEDs — ~585–595nm, Vf ~2.1V
• White LEDs — ~6000K, Vf ~3.2V
• Total: 20 LEDs (mixed colors)

Key Specifications

• Package: 3mm diffused | Current: 20mA max
• Forward voltage: 2.0–3.4V (color dependent)
• Viewing angle: 60° (diffused)
• Compliance: RoHS compliant

3mm vs 5mm LEDs

• 3mm (this pack): Smaller footprint — fits tighter PCB layouts and compact enclosures
• 5mm: Larger, brighter — better for panel indicators and breadboard use

Typical Applications

• Compact PCB status indicators
• Tight enclosure panel-mount indicators
• Arduino digital output status LEDs
• Electronics education and learning projects
• Breadboard prototyping with compact LEDs
