Notes:

1.

Maximum of 5 seconds with soldering iron. Duration can be extended to 10 seconds when flow soldering. RMA flux is recommended.

2.

De-rate linearly at 1.0mA /

°C above 25°C .

3.

The component must be actively aligned into the mating fiber cable assembly to achieve optimal performance.

4.

No Pre-bias.

5.

All Optek fiber optic LED products are subjected to 100% burn-in as part of its quality control process. The burn-in conditions are 96

hours at 100mA drive current and 25

°C ambient temperature.
