Overview
The Dialight 5219216F is a red diffused 3mm through-hole LED designed for general indication purposes, emitting light at a dominant wavelength of 625nm with a typical forward voltage of 2V at 10mA. While its diffused lens offers a wide 60° viewing angle for broad visibility, engineers must consider the inherent trade-off between diffusion and luminous intensity; increased diffusion can reduce the perceived brightness (8.7mcd at 10mA) compared to a clear lens, necessitating careful placement or higher drive currents in ambient light-sensitive applications.
Key Features
- Color: Red (625nm dominant wavelength)
