MGJ1D151505MPC-R7

Product Overview

The MGJ1D151505MPC-R7 from Murata Power Solutions Inc. is a surface-mount isolated module DC DC converter in the MGJ1 (1W) series. It accepts a 13.5V to 16.5V input and provides two outputs: 15V and -5V, each with a maximum current of 50mA, for 1 W total output power. The module specifies 5.7 kV isolation, 69% efficiency, over-temperature protection, and short-circuit protection. Its 8-SMD package measures 0.79 in L x 0.59 in W x 0.17 in H (19.9 mm x 15.0 mm x 4.4 mm), and it operates from -40°C to 105°C with derating.

Key Features

• Isolated module topology with two outputs
• Input voltage range: 13.5V to 16.5V
• Output 1: 15V at maximum 50mA
• Output 2: -5V at maximum 50mA
• Total output power: 1 W
• Voltage isolation: 5.7 kV
• Over-temperature and short-circuit protection
• Surface-mount 8-SMD module package
• Operating temperature: -40°C to 105°C with derating
• Efficiency: 69%

Applications

• Commercial information technology equipment requiring isolated board-level power conversion.
• Instrumentation or measurement systems that need separated positive and negative auxiliary rails.
• Compact surface-mounted commercial devices where a 1 W isolated converter provides auxiliary power to a board subsystem.

Design & Procurement Notes

When selecting this module, verify that the system input remains within 13.5V to 16.5V and that the 15V and -5V loads each stay within 50mA. The 1 W total output rating and 69% efficiency value should be used to estimate heat dissipation, especially as ambient temperature approaches the upper end of the -40°C to 105°C range with derating. The 5.7 kV isolation should be considered during board layout and insulation planning, and the surface-mount 8-SMD package should be matched to the PCB footprint and assembly process. OTP and SCP support protection-oriented design, but the actual load current, input range, and thermal margin should be checked against the application requirements.
