- Values based on 350mA and a Thermal Pad temperature of 25 °C.
- Viewing angle is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value.
- This is the maximum operating current that we recommend for this LED. Higher drive currents may be possible, but will require careful design of a suitable cooling system.
- At 350mA.
- Typical thermal resistance from the LED Junction to the bottom of the FR4 board.
- This is the value we recommend you use for determining driver input voltage.
* Results will vary depending on the quality of the dielectric material used in the MCPCB base.
