Assorted LED's 20 pack 276-1622

These are standard 5mm T-1¾ LEDs in multiple colors (red, green, yellow, etc.). The exact electrical characteristics vary slightly by color, but here are the typical specs for this pack:

🔌 Electrical Specifications

• Forward Voltage (Vf):

  • Red / Yellow: 1.8 – 2.2V

  • Green: 2.0 – 2.4V

  • Blue / White (if included in some packs): 3.0 – 3.4V

• Forward Current (If): 20mA (typical max rating)

  • They can operate lower (e.g., 5–10mA) with reduced brightness.

• Power (Watts):

  • P = V × I

  • For red/yellow (~2V × 20mA): 0.04W (40mW)

  • For green/blue (~3V × 20mA): 0.06W (60mW)

• Polarity (Diode Type): Standard Light Emitting Diode (LED)

  • Anode = longer lead

  • Cathode = shorter lead (and flat side of LED lens)

📏 Physical

• Size: 5mm (T-1¾) round lens

• Viewing angle: ~20–30° (narrow beam, typical of standard LEDs)

⚡ Usage tip: Always use a current-limiting resistor in series. For example, on a 12V supply with a red LED (2V drop at 20mA), resistor ≈ (12V - 2V) ÷ 0.02A = 500Ω (use 470–560Ω).
