Murata NMUSB202MC dual-port USB data isolator. Surface mount isolators provide an isolation barrier between the computer and two connected USB devices, helping to extend the effective disconnection 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-compatible surface mount module that provides dual-port USB data isolation from a single upstream port, each with a full 500mA downstream Power port. This 5V 1.3A USB data isolator has the function of automatically switching between a low speed of 1.5Mbits per second and a full speed of 12Mbits per second.
The NMUSB202MC-powered dual-port USB data isolator features 1-second 3kVAC isolation, downstream short-circuit and overload protection, and power surge notification. It has proven integrity and is well-suited for harsh environments with EMI or electrostatic discharge (ESD) risk .
Suitable applications include industrial and medical technology, where non-isolated USB power supplies can damage peripherals or users, or EMI can cause inaccurate data readings.
