Murata Introduces ‘NXJ1T’ Highly Insulated Compact DC-DC Converter for Industrial, Energy and Medical Applications

(hereinafter referred to as ‘Murata’) is pleased to announce the launch of the NXJ1T Series (hereinafter referred to as ‘this product’), a highly insulated compact DC-DC converter for the industrial, energy, and medical fields. NXJ1T Series’ (hereinafter referred to as “this product”). The NXJ1T Series features high insulation (4.2kV DC insulation withstand voltage), low leakage current, and high reliability, and is suitable for use in the industrial and energy fields, which require operation in high-voltage environments, as well as in the medical field, which requires higher levels of safety. Samples are now available.

In recent years, industries have been demanding higher performance from equipment and its supporting systems. In the industrial and energy sectors, high-performance applications such as 800V electric vehicles (EVs) and their charging equipment, battery energy storage systems (BESSs), and renewable energy infrastructures are becoming increasingly popular. To ensure their stable operation, communication interfaces and sensing circuits require increased insulation performance. On the other hand, in the medical field, it is crucial to ensure the safety of medical devices that come into direct contact with the human body. In this context, DC-DC converters with high insulation performance and high reliability are more effective in supporting efficient and stable operation of electronic devices.

To support higher performance requirements more effectively, Murata has developed this product with high insulation (4.2kV DC insulation withstand voltage), low leakage current, and high reliability. Its high insulation withstand voltage contributes to the overall reliability of the equipment and is suitable even in high-voltage environments. The low leakage current design supports stable operation of the devices and is also suitable for use in applications that require greater safety, such as medical devices that are directly connected to the human body. Furthermore, Murata's proprietary packaging technology achieves better thermal performance, and the products are capable of withstanding more than 1,000 cycles of temperature cycling tests from -40°C to 125°C. In addition, the package of the NXJ1T series prevents the intrusion of dust and fine particles and protects the internal devices and circuits to ensure higher reliability. As a result, they are able to cope with a wide range of applications from the industrial and energy fields to the medical field. In addition, the products achieve a high conversion efficiency of approximately 80% while realising a miniaturised design (10.55mm x 13.70mm x 4.04mm), which contributes to further savings in equipment space and energy consumption.

Going forward, Murata will continue to contribute to the creation of a safe and sustainable society through technological development aimed at improving the reliability and safety of its products.
