Maximum ratings are package-dependent. The above ratings were determined using lamps in chip-on-MCPCB (metal core PCB) packages for
characterization. Ratings for other packages may differ. Junction temperature should be characterized in a specific package to determine limitations.
Assembly processing temperature must not exceed 325°C (< 5 seconds).

expected by manufacturer in large quantities and are provided for information only. All measurements were made using lamps in T-1 3/4 packages
(with Hysol OS4000 epoxy encapsulant and clear epoxy die attach). Optical characteristics measured in an integrating sphere using Illuminance E.
The maximum forward current is determined by the thermal resistance between the LED junction and ambient. It is crucial for the end-product to be
designed in a manner that minimizes the thermal resistance from the LED junction to ambient in order to optimize product performance.
