Murata Power Solutions MEF1 DC/DC Converter 3.3V DC Output 300 mA 5.25V DC Max Input Through Hole DIP Package MEF1

Murata Power Solutions MEF1 DC/DC Converter (Model MEF1, MPN MEF1S0503SPC) delivers a precise 3.3V DC output at 300 mA from an input range of 4.75V to 5.25V DC, with a maximum output power of 1 watt. This through-hole discrete component features a compact DIP package measuring 19.65 mm by 19.65 mm with a depth of 10.15 mm, ideal for integration into electronic assemblies requiring stable low-voltage regulation.

The MEF1 series offers robust electrical isolation with 1kV DC input to output isolation, ensuring protection and signal integrity in sensitive industrial, laboratory, and instrumentation applications. The device operates reliably across a wide temperature range from -40°C to 85°C, supporting use in rigorous environmental conditions.

This converter exhibits low output ripple and noise (30mV peak-to-peak) and efficiency of 68.5%, optimizing power usage in compact electronic systems. Its fully encapsulated design with toroidal magnetics enhances durability and electrical performance. The device uses a through-hole DIP package with 6 pins for secure mounting on printed circuit boards.

Applications include powering sensors such as pressure transducers, Hall Effect sensors, and mass airflow sensors where regulated voltage supplies are critical. The DC/DC converter ensures steady output even where input voltage is not tightly controlled, making it highly reliable for embedded electronics, measurement instruments, and other industrial control systems.
