Yellow LED 5MM
💡 5 mm Yellow LED (Diffused)
📝 Overview
A standard 5 mm yellow LED with a diffused lens, ideal for status indicators, panel lights, and Arduino-based projects. It emits a warm yellow light and fits easily into breadboards and PCBs.
🔍 Key Features
Forward voltage: ~1.8–2.2 V
Forward current: up to 20 mA (recommended 16–18 mA)
Luminous intensity: 150–210 mcd (typical)
Wavelength: ~585–590 nm (yellow)
Viewing angle: ~60° (diffused lens)
Package: TO‑92 5 mm round, flat face, long lead = anode
✅ Typical Arduino Setup
Use with a current-limiting resistor:
5 V ── 220 Ω ── Anode (long lead) Cathode (short lead, flat side) ── GND
Use Arduino:
pinMode(LED_PIN, OUTPUT); digitalWrite(LED_PIN, HIGH);
For PWM brightness control:
analogWrite(LED_PIN, value); // value: 0–255
🎯 Applications
Indicator LEDs on PCBs and enclosures
Visual feedback for microcontroller projects
Signal lamps in DIY electronics
Educational and prototyping tasks
