Mingjiada Electronics stocks a range of mainstream models and supports both small-batch samples and large-volume orders. Relying on an efficient logistics system, we ensure rapid product delivery.

[Murata] Isolated Gate DC-DC Converters
Murata Manufacturing’s DC-DC converter modules are power supply modules comprising only input/output capacitors and a few components, typically used in new energy, motion and control, mobility and healthcare solutions. Furthermore, their compact size and high efficiency enable them to effectively meet the stringent spatial and temporal requirements faced by engineers.

Key Model Series Overview
MGJ1T/MGJ1D 1W Surface-Mount Isolated Driver Power Supply
Isolation voltage up to 6kVDC with reinforced insulation; wide input range of 12/15/24V; dual asymmetric positive and negative outputs (+15V/-3V, +15V/-5V, +18V/-2.5V); CMTI (Common-Mode Transient Immunity) > 100 kV/μs, ultra-low isolation capacitance of just 3–13 pF, significantly suppressing high-frequency switching EMI, suitable for high-speed driving applications with SiC power devices.
MGJ2D 2W Through-Hole Gate DC-DC
A classic industrial-grade, general-purpose model with 5.2 kVDC isolation withstand voltage, 12/15V input, and standard dual outputs of +15V/-8.7V. It features self-recovering output short-circuit protection, operates within a temperature range of –40°C to +105°C, and meets the creepage distance requirements for high-voltage inverter safety standards. It is a mainstream standard component for inverters and servo drives.
MGJ6D 6W High-Power Isolated Gate Converter
5.7 kVDC withstand voltage; output voltage optimised specifically for high-power SiC modules; supports 3 kV DC bus systems; enhanced reliability thanks to a photocoupler-free feedback architecture; stable operation at 105°C under full load; suitable for high-power applications such as energy storage PCS, high-power photovoltaic inverters and on-board charger (OBC) fast charging systems
