Description
The WDYJ-65 is a 1-channel Axial Vactrol features a very low "on" resistance, fast response time, with a smaller temperature coefficient.
Linear Optocoupler is an optoelectronic devices , to control resistance change by input current change, made of CdS and LED semiconductors after rigorous selection ,aging and testing.
Features
High Input-to-output Voltage Isolation
True Resistance Element Output
Suitable for AC or DC Use
Low Drive Current
Low On Resistance, High Off Resistance
Complete Solid-state Construction
Main characteristic curve
Attention : Soldering pin recommended away from the bottom of optocoupler, soldering time should be as short as possible.
