4pcs 3mm led green

🔹 4PCS 3mm Green LED (Diffused)

A pack of four standard 3mm green diffused Light Emitting Diodes. Ideal for status indicators, panel lights, and DIY electronics projects. The diffused lens provides a wide, soft viewing angle.

✅ Specifications:

• Color: Green

• Lens Size: 3mm (T-1)

• Lens Type: Diffused (Non-Clear)

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

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

• Maximum Forward Current: 30mA (Peak, continuous use below this)

• Luminous Intensity: Medium (Varies by bin; typical ~1000-4000 mcd)

• Viewing Angle: ~60° (Diffused)

• Leg Type: Axial Leads

• Cathode Identification: Shorter lead and flat side on the lens rim

• Quantity: 4 pieces

⚙️ Features:

• Low Power Consumption: Operates at low voltage and current.

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

• High Visibility: Green light is highly visible and commonly used for “power on” or “go” status.

• Diffused Light: Provides a soft, even glow without a harsh central hotspot.

• Long Lifespan: Solid-state design ensures reliable, long-term operation.

📦 Applications:

• Status Indicators: Power on, system active, or mode indicators in devices.

• DIY Electronics & Prototyping: Arduino, Raspberry Pi, and breadboard projects.

• Panel Lights & Backlighting: For switches, instruments, and displays.

• Model Lighting: For scale models, costumes, and hobby projects.

• Educational Projects: Learning basic electronics and circuit design.

🔧 Usage Guide:

1. Always Use a Current-Limiting Resistor! Connecting directly to a power source will destroy the LED.

2. Identify Polarity:

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

   • Anode (+): Longer lead.

3. Resistor Calculation: Use Ohm’s Law: R=(Vsupply−Vf)/IfR=(Vsupply​−Vf​)/If​.

   • Example for 5V supply: $R=(5V-2.2V)/0.020A=140\Omega$. A standard 220Ω resistor is a safe, common choice.

4. Soldering: Use a low-temperature iron and avoid prolonged heat on the leads to protect the internal structure.

⚠️ Important Notes:

• Polarity Sensitive: Will not light if installed backwards.

• Do Not Exceed Ratings: Operating above 20-30mA continuously will drastically shorten lifespan or cause immediate failure.

• Heat Sensitivity: Excessive heat during soldering can damage the LED.

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