NCM3 Isolated 3W 4:1 Input DC-DC Converters

Murata Electronics NCM3 Isolated 3W 4:1 Input DC-DC Converters offer a 9V to 36V voltage range, 5kV_AC isolation rating, and -40°C to +105°C operating temperature range. These converters feature an SMD package that enables high-speed automated product placement, continuous short-circuit protection, and a leakage current rating of <1μA. Murata Electronics NCM3 Converters have UL 62368-1 250Vrms reinforced insulation and are pending ANSI/AAMI ES60601-1 for 2 MOPP, providing mains safety isolation. NCM3 converters are suitable for medical and other high-voltage applications.
