DESCRIPTION
The LTC-268CKS-P is a 0.28 inch (7.00mm) digit height triple
digit SMD display. This device uses AlInGaP Yellow LED
chips(AlInGaP on a non-transparent substrate). The display has
black face and white segments.

Luminous Intensity Matching Ratio
Note:
1. Luminous intensity is measured with a light sensor and filter combination that approximates
the CIE (Commision Internationale De L’Eclairage) eye-response curve.
2. Reverse voltage is only for IR test. It can not continue to operate at this situation.
