Module provides data and power isolation in critical USB environments

  • Power Devices


Murata announces the introduction of the NMUSB202MC, a surface mount powered data isolator module that conveniently provides dual port USB data and power isolation from a single upstream port. When used in conjunction with a host controller, a single NMUSB202MC module counts as two USB hubs for cascaded applications and provides full 5V/500mA power to each downstream port. 250VRMS reinforced isolation provides safety, immunity to EMI, and elimination ground loops.

The NMUSB202MC module’s full compliance with USB 2.0 specification enables hassle-free, “plug and play” operation with any USB-compatible device. The module is able to switch automatically between full-speed operation (12Mbps) and low speed (1.5Mbps) as the application requires.

With an operating range from -40°C to +85°C, the NMUSB202MC meets requirements for industrial controls, sensor communications, and harsh environment installations. The high insulation resistance and 3kV isolation makes the NMUSB202MC ideal for use in medical environments. Advanced surface mount design enables the USB isolation function with a single SMT component. Murata’s proprietary manufacturing assures competitive pricing with a 3.3MHrs MTBF.
