OPI1264 Series

Optically Coupled Isolators

This

ATEX &IECEx CERTIFIED

component

is RoHS

compliant

Pb

The OPI1264A/B/C/D are a family of optically coupled isolators,each consisting of a infrared light

emitting diode, coupled to an NPN silicon phototransistor sealed in an injection moulded plastic

housing.This series is designed for applications requiring high voltage isolation between input and

output.

All electrical parameters are 100% tested by manufacturing. Specifications are guaranteed to a 0.65%
