Notes:
1. All dimensions are in millimeters (inches).
2. Tolerance is ±0.25(0.01") unless otherwise noted.
3. Lead spacing is measured where the leads emerge from the package.
4. The specifications, characteristics and technical data described in the datasheet are subject to change
without prior notice.
Notes:
1. θ1/2 is the angle from optical centerline where the luminous intensity is 1/2 of the optical peak value.
2. Radiant Intensity / luminous flux: +/-15%.
* Radiant intensity value is traceable to CIE127-2007 standards.
REMAK :The IR LED can be driven at 100mA, with at a max pulse width of
20ms,The maximum duty cycle is 20%.
