Würth Elektronik WL-OCHS High-Speed Optocouplers

Würth Elektronik WL-OCHS High-Speed Optocouplers are designed to expand the portfolio with reliable galvanic isolation solutions for fast digital communication. These optocouplers support data rates from 1 MBd up to 10 MBd combines fast switching times from 20 ns to 800 ns for precise signal transmission. The WL-OCHS optocouplers offer high isolation voltages of 3750VRMS and 5000 VRMS.  With high noise immunity enabled by strong CMTI performance and low internal coupling capacitance, WL-OCHS is well suited for applications such as industrial controls and automation.
