Understanding Red SMD LEDs: A Guide to Common Packages (2835, 5050, 5730, etc.)

Red Surface-Mount Device (SMD) LEDs are fundamental components in modern lighting and indication, prized for their efficiency, compact size, and versatility. The "package" size (e.g., 2835) critically determines the LED's physical dimensions, power handling, light output, and optimal application. Here’s a breakdown of popular red SMD LED packages.

Key Characteristics of Red SMD LEDs

Before diving into packages, remember two key specs for red LEDs:

Typical Wavelength: ~620-630nm (standard red) to ~660nm (deep red)

Forward Voltage (Vf): Generally lower than white/blue LEDs, typically 1.8V - 2.2V.
