Isolation provides effective breaking of ground loops and immunity to EMI in harsh environments as found in industrial and medical applications. Full speed (12Mbps) and low speed (1.5Mbps) are supported with automatic switching. Input power of 5V is provided by an external ‘adapter’ or system voltage rail. Power surge notification Patents Pending 3D Model available For full details go to www.murata-ps.com/rohs 1. Components are supplied in tape and reel packaging, please refer to package specification section. Orderable part numbers are NMUSB202MC-R7 (23 pieces per reel), or NMUSB202MC-R13 (92 pieces per reel). All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified. www.murata-ps.com/support KDC_NMUSB202MC.B01 Page 1 of 8 NMUSB202MC Powered Dual Port USB Data Isolator DC-DC CHARACTERISTICS INPUT CHARACTERISTICS Parameter Conditions Min.

Murata Power Solutions NMUSB202MC data isolator is 100% production tested at its stated isolation voltage. This is 3kVAC for 1 second. The NMUSB202MC series has been recognized by Underwiters Laboratory to 250 Vrms Reinforced Insulation. REPEATED HIGH-VOLTAGE ISOLATION TESTING It is well known that repeated high-voltage isolation testing of a barrier component can actually degrade isolation capability, to a lesser or greater degree depending on materials, construction and environment. We therefore strongly advise against repeated high voltage isolation testing, but if it is absolutely required, that the voltage be reduced by 20% from specified test voltage. SAFETY APPROVAL ANSI/AAMI ES60601-1 The NMUSB202MC series is pending recognition ANSI/AAMI ES60601-1 and provides 2 MOOP (means of operator protection) based upon a working voltage of 250 Vrms max., between Primary and Secondary. UL 60950 The NMUSB202MC series has been recognized by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 250Vrms. FUSING The NMUSB202MC series of converters are not internally fused so to meet the requirements of UL an anti-surge input line fuse should always be used with ratings as defined below. NMUSB202MC - 2.5A (125Vdc rated) All fuses should be UL recognized and rated to at least the maximum allowable DC input voltage. RoHS COMPLIANCE, MSL AND PSL INFORMATION NMUSB202MC is compatible with RoHS soldering systems with a peak reflow solder temperature of 245ºC as per J-STD-020D.1. The pin termination finish on this product series is Gold with Nickel Pre-plate. The series is backward compatible with Sn/Pb soldering systems. The product has a Moisture Sensitivity Level (MSL) 3.
