Murata Power NMUSB202MC Dual-Port USB Data Isolator

Murata Power has released the NMUSB202MC Dual-Port USB Data Isolator. 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.

The product is a USB 2.0-compliant surface-mount module that supplies dual-port USB data isolation from a single upstream port with full 500 mA power available from each downstream port. The 5 V, 1.3 A USB data isolator features automatic switching between low speed at 1.5 Mbps and full speed at 12 Mbps.

Featuring verified integrity through 3 kVAC isolation, downstream short-circuit and overload protection and power surge notification, the device is suitable for harsh environments with risk of EMI or electrostatic discharge (ESD). Applications for the isolator include industrial and medical technologies, where non-isolated USB power can damage peripherals or users or EMI may cause inaccurate data readings.
