10mm LED Yellow

The 10mm Yellow LED is a high-visibility, energy-efficient through-hole indicator ideal for prototyping, DIY electronics, and professional lighting accents. Its large-diameter lens delivers excellent visibility, making it a reliable choice for Arduino, Raspberry Pi, and other microcontroller-based projects that require clear status indication or decorative illumination.

Key Features 🔍

• High brightness with a large 10mm lens for superior visibility
• Low power consumption — ideal for battery-powered builds
• Long service life with solid-state reliability
• Wide viewing angle (diffused options) for even, soft illumination
• Easy to use through-hole package — breadboard- and perfboard-friendly

Technical Specifications 📐

• Package: 10mm (T-10) round, through-hole LED
• Color (Wavelength): Yellow, typically 585–595 nm
• Forward Voltage (Vf): ~2.0–2.2 V (typical at 20 mA)
• Forward Current (If): 20 mA nominal (do not exceed device maximum)
• Luminous Intensity: Model-dependent; typically high-output for 10mm package
• Viewing Angle: Up to ~120° for diffused lens; ~30–45° for clear lens
• Polarity: Longer lead = Anode (+), shorter lead / flat edge = Cathode (−)
• Interface Voltage: Compatible with 3.3 V and 5 V logic when used with a series resistor

Resistor selection tip ⚡: R = (Vsupply − Vf) / If. Examples: 5 V → ~150 Ω (for 20 mA), 3.3 V → ~68 Ω (for 20 mA). Adjust current for desired brightness.

Integration with Microcontrollers 🔗

• Directly interfaces with Arduino, Raspberry Pi, ESP32, and similar modules via a current-limiting resistor
• Suitable for PWM dimming from GPIO pins for brightness control
• Works on breadboards, perfboards, and custom PCBs as a standard electronics component

Typical Applications 🧰

• DIY projects and educational kits
• Architectural lighting accents and markers
• Signage and channel-letter backlighting
• Decorative lighting, indicators, and spotlight accents
• Commercial displays and control panel indicators

Setup and Usage Tips 🔧

• Always use a current-limiting resistor to protect the LED
• Verify polarity before powering: Anode (+) to supply via resistor, Cathode (−) to ground
• For wider, softer light, choose a diffused lens; for tighter beams, use a clear lens

Whether you’re building a quick prototype or integrating an indicator into a finished product, this 10mm Yellow LED provides dependable performance with simple, robust operation for both hobbyists and electronics engineers.
