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.
