100PCS/lot 3mm 5mm F3 F5 Round LED Ultra Bright White Green Yellow Blue White Red Light Emitting Diode For Diy Kit

Light up your electronics with a reliable pack of 100 round LEDs in 3mm and 5mm diameters. Designed for DIY kits, hobby projects, and everyday electronics, these ultra-bright diodes deliver vivid color indicators and visual feedback wherever you need it.

• Color variety: Red, Yellow, Blue, Green, and White—perfect for color-coding signals, statuses, or simply adding a splash of illumination to your project.
• Size and pins: Head diameter options of 3mm and 5mm with 18mm long leads for easy insertion into breadboards, PCBs, or prototyping boards.
• Voltage and current: Red/Yellow LEDs operate at 1.8–2.3V with a typical 20mA current; Blue/Green/White LEDs operate at 2.8–3.6V with a typical 20mA current. Drive them with an appropriate current-limiting resistor for safe operation.
• Construction: Environmentally friendly oxygen resin construction that withstands higher temperatures, helping maintain brightness and longevity in demanding environments.
• Package type and origin: Grouped as surface-mount style components, sourced from Mainland China for a consistent, budget-friendly LED set.

Why this LED set stands out

• 100 pieces in one value-packed lot give you ample supply for multi-project builds, inventory for repairs, or classroom teaching kits.
• Distinct color options let you implement clear, intuitive indicators—great for Arduino projects, PCB circuits, indicators in electronics dashboards, and DIY gadgets.
• Bright illumination with reliable color rendering ensures visibility in both low- and bright-light conditions, making status signals instantly recognizable.

Ideal applications and practical guidance

• Indicator lights on Arduino projects, microcontroller interfaces, and educational kits—to signal power, logic states, or events.
• DIY LED projects, PCB circuits, and small display panels where color coding improves usability.
• Home, office, and industrial equipment indicators to provide quick status feedback or alerts.

Usage tips

• Always include a suitable current-limiting resistor to maintain the recommended 20mA forward current, using color-specific forward voltage as a guide.
• Match the LED color to your supply voltage: Red/Yellow typically use lower Vf (1.8–2.3V); Blue/Green/White require higher Vf (2.8–3.6V).
• Plan for lead length and mounting: with 18mm leads, these LEDs are well-suited for prototyping on breadboards or PCB insertion.
