Murata Power Solutions 2W DIP Dual Output Unregulated Isolated DC-DC Converter, 9V dc / 111 mA Output, 4.5-5.5V dc NMH0509DC

Murata Power Solutions NMH0509DC is a 2W dual output isolated DC-DC converter housed in a compact 14-pin DIP through-hole package, designed for reliable voltage conversion and power isolation in industrial and electronic applications. It efficiently converts 4.5V to 5.5V DC input voltages to stable ±9V DC outputs at a current rating of 111 mA per output, making it suitable for powering sensitive analog and digital circuits where noise isolation is critical.

This converter features an internal surface-mount device (SMD) construction combined with UL 94V-0 flame retardant package material to ensure durability and safety. The unit achieves high efficiency of 81% while maintaining low ripple and noise of 200mV peak-to-peak, which supports stable operation in precision electronic equipment.

With an isolation voltage of 1 kV DC, the NMH0509DC provides excellent safety and reduces interference between input and output circuits. The device is RoHS compliant, meeting environmental protection standards, and is capable of operating in a broad temperature range from -40°C to 85°C, making it ideal for harsh industrial, laboratory, telecommunications, and commercial electronics environments.

This converter requires no external components, simplifying integration and reducing overall system cost. The high Mean Time Between Failures (MTBF) of 663,000 hours under MIL-HDBK-217F (25°C) standards ensures extended operational reliability critical in continuous operation setups.

Dual output isolated DC-DC conversion at 2W nominal power. Wide input voltage range of 4.5 to 5.5V DC for flexible powering options. Compact 14-pin DIP through-hole package with UL 94V-0 flame retardant plastic. Input/output isolation voltage of 1 kV DC for enhanced circuit protection.
