Product Description
Murata Power Solutions MEJ1 is a series of isolated 1 Watt SIP single-output DC/DC Converters designed to provide reliable power conversion with high safety and isolation standards. The MEJ1 model features a 9V DC output at 200 mA, with input voltages ranging from 4.5V to 5.5V DC. Packaged in a compact 7-pin SIP through-hole mount form factor, it offers a small footprint (19.65mm x 9.8mm x 12.65mm) suitable for integration into various industrial and medical power designs.
This converter complies with the third edition of medical safety standards, providing 2 MOOPs based on 200 Vrms working voltage between primary and secondary circuits and 1 MOOP between the primary and enclosure, enhancing operator protection in critical applications. The device's maximum isolation voltage is 5.2 kV DC, making it ideal for applications requiring a high degree of isolation such as agency-approved safety barriers for medical equipment.
Featuring a high energy efficiency of 74%, the MEJ1 series delivers stable power with a ripple and noise of 70 mV Pk-Pk, supporting low noise voltage-sensitive circuits. It operates reliably across a broad temperature range from -40°C to +85°C. The encapsulated SIP package incorporates UL 94V-0 flame-retardant material and toroidal magnetics for enhanced durability and thermal regulation.
Typical usage includes IGBT drivers, control systems, medical instrumentation, and other low power electronics requiring safety isolation. The MEJ1 converter is pin compatible with Murata's MEV, NMV, NMK, MEJ2, and NMJ series, simplifying system upgrades and replacements.
The converter delivers a stable 9 V DC output at up to 200 mA current. It accepts supply voltages from 4.5 to 5.5 V DC, ensuring wide input compatibility. 7-pin SIP package offers through-hole mount ease and compact size.
Isolation voltage rated at 5.2 kV DC enhances electrical safety. Compliant with RoHS and UL safety certifications for quality assurance. High reliability with MTBF of approximately 3.9 million hours. Energy efficient conversion at 74% typical efficiency reduces heat generation.
Suitable for industrial, medical, and control system applications. Operating temperature from -40°C to +85°C for harsh environment use.
