Selection Guide
Absolute Maximum Ratings at TA=25°C
Notes:
1. Results from mounting on metal core PCB,mounted on pc board-metal core PCB is recommend.for lowest thermal resistance.
2. 1/10 Duty Cycle, 0.1ms Pulse Width.
Notes:
1. θ1/2 is the angle from optical centerline where the luminous intensity is 1/2 of
the optical peak value.
2. Luminous intensity/ luminous Flux: +/-15%.
