absolute maximum ratings: (Tamb=25°C) All specifications are subject to change without notice. 1. IF = 20mA 2. Millicandela is a unit of measurement for the light output of LEDs. Candela is one of the seven base units of the International System of Units. It is a unit of Luminous Intensity (I), or Light Power per Steradian (SR), while steradian is a unit of 3D cone angle with which the projected area of 1 steradian over a sphere with a 1m radius, is 1 square meter. One thousand millicandela equals one candela or approximately one candle power. 3. (1/10th duty cycle, 0.1ms pulse width) 4. (VR = 5V) |

Excellent Counter Illumination
This product has a robust, easily connected package format with compact size.
It does run hot enough at rated voltage to need heat sinking of some sort if
application requires full illumination.
I found that it works well at 10V /100ma without a heat sink, reduced light
output of course but hopefully also extended life.
