Murata Power Solutions 1W Single Output Unregulated Isolated DC-DC Converter 5V DC Output, 4.5-5.5V DC Input, Through MER1

Murata Power Solutions MER1S0505SC is a 1 watt Single Output Unregulated Isolated DC-DC Converter designed for reliable voltage conversion with galvanic isolation. This model provides a fixed 5V DC output at 200 mA current from a DC input voltage range of 4.5 to 5.5 volts. Its compact through hole SIP package includes a standard 6-pin configuration, ideal for integration on control system boards and industrial electronics.

The converter achieves up to 84% efficiency with fully encapsulated toroidal magnetic components, no electrolytic or tantalum capacitors, and UL94V-0 rated package materials, ensuring long-term durability and safety. It operates reliably over a wide ambient temperature range from -40°C to 85°C and features a high mean time between failures (MTBF) of approximately 7.68 million hours, indicating excellent reliability for industrial and commercial applications.

This DC-DC converter offers 1kV DC galvanic isolation, which enhances noise reduction and protects sensitive equipment in demanding environments such as measurement systems, industrial control, telecommunications, and power management applications. The device does not require external heatsinks or additional components for standard output power, simplifying PCB design and reducing overall system cost.

Mounting is via through hole pins with a SIP package measuring 19.65 mm in length, 6.15 mm in width, and 10.15 mm in depth. The weight of 2.25 grams makes it suitable for compact electronic systems. To meet UL 60950 requirements, an appropriate anti-surge input fuse is recommended, with ratings specified per model variant.
