Murata announced the MGJ2 series, a new line of surface mount DC-DC converters. 

The MGJ2 series consists of six models. Each lightweight unit has a 2 W power rating and are supplied in compact, low-profile form factor modules measuring just 19.49mm x 14.99mm x 4.39mm dimensions. 

Available in 12 V and 15 V voltage rails, they feature +15V/-5V, +15V/-9V, and +20V/-5V bipolar outputs. 

The series’ characterized partial discharge performance ensures that functionality can be maintained regardless of the demanding nature of the high-voltage applications they are aimed for. 

The DC-DC converters have a low isolation capacitance of 3pF and a common-mode transient immunity (CMTI) that exceeds 200kV/µs. 

According to the company, other key features include:
•    Continuous barrier that endures voltage that reaches 2.5kV plus 
•    9mm creepage and clearance separation distances
•    An extended operational temperature range of -40˚C to +100˚C
•    Built-in short circuit protection mechanisms. 
•    Certified UL62368 compliant for 250VAC reinforced insulation 
•    ANSI/AAMI ES60601-1 certification is currently pending. 

The MGJ2 series are intended to accompany the IGBT and SiC-based MOSFET high-voltage gate drivers used in industrial, renewable energy, and mobility applications.
