500piece 3 mm LED diode kit with mixed colors: red, green, yellow, blue, white. A practical collection of throughhole LEDs for prototyping, repairs, education, and hobby projects. Key benefits Large mixed set: 500 LEDs in five common colors for flexibility across many projects. Compact 3 mm package: small footprint for tight spaces on perfboard, model work, and compact enclosures. Easy to use: standard twolead design for quick insertion into breadboards and soldering to PCBs. Versatile and practical: ideal for status indicators, decorative lighting, and basic electronic learning. Cost effective way to stock spare components and reduce downtime during development or . Important attributes Function: discrete indicator light source for low current circuits and signaling applications. Compatibility: compatible with standard circuits that accept 3 mm throughhole LEDs and common prototyping platforms. Use a current limiting resistor appropriate to your supply voltage. Size: 3 mm LED package diameter, two leads for throughhole mounting. Material and construction: typical plastic package with metal leads suited for soldering and breadboard use. Performance: designed for low current operation common to small indicator LEDs and general purpose electronics. Typical applications Prototyping and learning: classroom labs, electronics workshops, and projects using breadboards and perfboards. Indicators and signals: status lights for DIY controllers, sensor indicators, and of appliances and toys. Models and decorative lighting: scale models, miniature scenes, and lowvoltage decorative installations. Usage notes Observe LED polarity when installing. The longer lead is usually the positive lead. Always include a current limiting resistor when connecting LEDs to a voltage source to prevent damage. Verify fit on your chosen breadboard or PCB layout prior to final assembly. Package contents 500 pieces of 3 mm LEDs in mixed colors: red, green, yellow, blue, white. This kit provides a versatile supply of small indicator LEDs for makers, students, technicians, and hobbyists who need a reliable mix of colors for prototyping and repairs.
