Assorted LED's 20 pack 276-1622
--THIS PRODUCT CONTAINS 20 PER PACK--
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).
