Product Description
Murata Power Solutions MEJ2 model is a medically approved, fully encapsulated DC/DC converter delivering 2 watts of power in a compact SIP through-hole package. It supports dual outputs of -3.3V and 3.3V voltage levels, operating with input voltages between 4.5V and 5.5V. This converter provides high voltage isolation of 5.2kV DC, making it suitable for industrial, medical, and high noise environment applications.
The MEJ2 series meets IEC 60601 (3rd Edition) medical safety standards, providing one measure of operator protection (MOOP) up to 200Vrms. The fully encapsulated construction features internal SMD components and toroidal magnetics to ensure durability and electromagnetic compatibility.
Designed with a small footprint of 19.65mm length, 9.8mm width, and 12.65mm depth, it occupies only 1.96cm² board area. The device offers a ripple and noise level of 40mV peak-to-peak with an efficiency rating of 71%, supporting improved power system performance and thermal management.
Its long mean time between failures (MTBF) of approximately 4.0 million hours assures high operational reliability for demanding applications. The package employs a 7-pin SIP type through-hole mounting design, compatible with Murata's MEV, NMV, NMK, and NMJ series converters.
The converter's operating temperature ranges from -40°C to 85°C, enabling use in harsh environmental conditions for industrial, laboratory, medical, and manufacturing power supply needs. This product is RoHS compliant and approved to UL 60950 and UL 60601 safety standards, ensuring environmental and electrical safety guidelines compliance.
Supports medically approved isolation and safety standards for critical applications. Compact SIP through-hole format for easy PCB integration. Wide temperature operation enables use in diverse industrial environments. High isolation voltage suitable for noisy and high-voltage scenarios.
Efficient power conversion reduces system energy losses. Reliable operation with extended MTBF ensures long product life. RoHS and UL certified for environmental and product safety.
