Murata and Matsushita Electric jointly developed a car with high heat-resistant film capacitors

In recent years, hybrid vehicles and electric vehicles continue to evolve, and the demand for miniaturization, weight reduction, capacity increase, and high heat resistance of the mounted electronic components is increasing. Murata Manufacturing Co., Ltd. (hereinafter referred to as "Murata") and MHI Co., Ltd. (hereinafter referred to as "Matsushita Electric Works") jointly developed the FH series of high-temperature-resistant film capacitors that can be continuously used under a high temperature of 125 ° C. The product is ideal for environmentally friendly car converters and motor drive converters that require warmer temperatures in the future. Samples will be available starting in September 2017 and will be available in April 2018 at Murata's FMCG Solutions. Production.

Today's high-temperature guaranteed requirements for capacitors for converters and motor drive converters have dramatically increased, and capacitors used on power cords have also required self-healing capabilities to prevent malfunctions in short-circuit mode. Compared to aluminum electrolytic capacitors, thin film capacitors have long lifetimes and are nonpolar, making them ideal for automotive electronics applications. However, the conventional high-heat-resistant thin-film capacitors are difficult to guarantee high temperatures exceeding 105 ° C, self-recovery functions in high temperature regions are hard to work, and there is a concern of short-circuit failure.

This time, Murata developed a new high-heat-resistant thin film material, which belongs to the category of thermosetting resin film as a dielectric, and the moon motor co-developed a 125 ° C high temperature environment can be used continuously in support of self Car repair with high heat-resistant film capacitors. It is understood that the business of Finishing Machinery covers capacitors and related equipment, devices, electrical equipment, devices, information machines and equipment, in the home appliances, automobiles, railways and electronics and other related products. In order to be able to provide more competitive high-quality products, Murata funded the acquisition of NHI by October 4, 2016 and set up a joint venture plant with a 65% stake in Murata. In the future, Murata will jointly develop new technologies and new products with Minamata Motor Co., Ltd. to speed up the product launch.
