VLSL31

Vishay Semiconductors High Brightness LED Power Module

Notes

(1) Forward voltages are tested at a current pulse duration of 1 ms and a tolerance of ± 0.1 V. Luminous flux is measured at a current pulse

duration of 25 ms and an accuracy of ± 11 %.

(2) Calculated based on single LED unit.

(3) VF classes are marked at the LED cluster and represent the technical classification only. The single groups cannot be specifically ordered.

(4) Based on theoretical calculation.
