Overview

The NME1S0505SC is a compact, 1W isolated DC-DC converter designed to provide a regulated 5V output from a 4.5V to 5.5V input. This module features 1kVDC galvanic isolation and is housed in a space-saving 4-pin SIP package, making it ideal for eliminating ground loop noise in digital circuits. It is fully encapsulated with toroidal magnetics to ensure reliable performance without the need for external filtering components.

Why Choose This Part

This module offers a high power density in an industry-standard 4-SIP footprint that is pin-compatible with several other Murata series. It requires no external components for operation and is UL62368-1 recognized, simplifying the safety certification process for commercial ITE designs.

Applications

Ground Loop Elimination
Provides 1kVDC isolation to break ground loops in sensitive analog-to-digital signal paths.
Digital Interface Isolation
Supplies isolated power to RS-485 or CAN bus transceivers to protect control logic from high-voltage transients.
Industrial Control Systems
Reliable operation in harsh environments with a wide operating temperature range up to 115 degrees Celsius.

Getting Started

Integration is straightforward as the device is a plug-and-play module requiring only a 4.5V to 5.5V source; however, designers should follow datasheet derating curves when operating near the 115 degrees Celsius limit. Standard 2.54mm pitch through-hole mounting allows for easy prototyping on universal perfboards or direct PCB soldering.
