Overview
Phototransistor optocoupler devices use the current changes to control the resistance change. It is a Linear optocoupler which through the strictly selected, aging, testing. Optocoupler isolation made up of CDS and LED. Package tyoe for LCR-0202 is DIP-4(cuboid small package). It is widely used in audio power amplifier protection and control.
It is recommend that the welding should be made at 4mm of lead wire far away from optoisolator’s seat, and the welding be completed in the shortest possible time.
Feature
Pure resistor and non-polarity output
Wide range of analog liner resistance, "on" at the low resistance. "off" at high resistance
Simple circuit configuration suitable for DC and AC use
Input to output isolation, and low distortion coupling
