4pcs 5mm Led Green

🔹4PCS 5mm Green LED (Diffused)

A standard pack of four 5mm green diffused Light Emitting Diodes. Perfect for status indicators, panel lighting, and a wide variety of DIY electronics and prototyping projects. The diffused lens provides a wide, even viewing angle.

✅ Specifications:

• Color: Green

• Lens Size: 5mm (T-1 3/4)

• Lens Type: Diffused

• Forward Voltage (Vf): 2.0V – 2.4V (Typical)

• Forward Current (If): 20mA (Standard operating current)

• Maximum Forward Current: 30mA (Peak)

• Luminous Intensity: Medium (Varies by bin)

• Viewing Angle: ~60° (Wide, diffused)

• Leg Type: Axial Leads

• Polarity: Cathode (-) is shorter lead; flat side on lens rim.

• Quantity: 4 pieces

⚙️ Features:

• Low Power Consumption: Efficient operation at common circuit voltages.

• Easy to Integrate: Standard axial leads for breadboarding, soldering, and PCB mounting.

• High Visibility: Green is a highly visible color for “power on,” “active,” or “go” status indicators.

• Wide-Angle Glow: Diffused lens creates a soft, even light without a sharp hotspot.

• Long Lifespan: Solid-state reliability with typical lifespans exceeding 50,000 hours.

📦 Applications:

• Status & Indicator Lights: Power, activity, and mode indicators in consumer electronics and DIY devices.

• Prototyping & Education: Essential for Arduino, Raspberry Pi, and breadboard circuits.

• Panel & Backlighting: Illuminating switches, dials, and instruments.

• Model & Decorative Lighting: For scale models, costumes, and art projects.

• Basic Circuit Learning: Fundamental component for understanding diodes, polarity, and current limiting.

🔧 Usage Guide:

1. Always Use a Series Resistor! Connect directly to a voltage source will destroy the LED.

2. Polarity Identification:

   • Cathode (-): Shorter lead. Flat side on the LED lens rim.

   • Anode (+): Longer lead.

3. Resistor Calculation: R=(Vsupply−Vf)/IfR=(Vsupply​−Vf​)/If​

   • Example for 5V supply: Using Vf=2.2VVf​=2.2V and If=20mAIf​=20mA:
     R=(5V−2.2V)/0.020A=140ΩR=(5V−2.2V)/0.020A=140Ω. A 220Ω resistor is a common, safe choice.

4. Soldering: Use a low-wattage iron. Avoid prolonged heat on the leads.

⚠️ Important Notes:

• Polarity Sensitive: Will not light if installed backwards.

• Current Limit: Do not exceed 20-30mA continuous current.

• Heat Sensitivity: Avoid excessive heat during soldering.

• ESD Protection: Handle with care to avoid static discharge.
