Device provides an isolation barrier between a computer and two connected USB devices

The Murata NMUSB202MC dual-port USB data isolator is now available from Mouser. The surface-mount isolator provides an isolation barrier between a computer and two connected USB devices, helping to extend effective breaking of ground loops and immunity to electromagnetic interference (EMI) while allowing data transmission. Murata Power Solutions' NMUSB202MC Powered Dual-Port USB Data Isolator, now available from Mouser Electronics, is a USB 2.0-compliant surface-mount module that supplies dual-port USB data isolation from a single upstream port with full 500mA power available from each downstream port. This 5V 1.3A USB data isolator features automatic switching between low speed at 1.5Mbits per second and full speed at 12Mbits per second. Featuring verified integrity through a 1-second 3kVAC isolation, downstream short-circuit and overload protection, and power surge notification, the NMUSB202MC Powered Dual-Port USB Data Isolator proves ideal for harsh environments with risk of EMI or electrostatic discharge (ESD). Suitable applications include industrial and medical technologies, where non-isolated USB power can damage peripherals or users, or EMI may cause inaccurate data readings.
