TDK has developed small, high-capacity ceramic multilayer surface mount capacitors for medium voltage applications

TDK Corporation recently announced the development of a ceramic multilayer surface mount capacitor for medium voltage applications with a rated voltage of 100V, and plans to start mass production and sales in July. This product adopts TDK's leading ceramic dielectric thin layer technology and stacking technology, which enhances the capacitance to the highest level of similar medium voltage products in the industry..diode

In recent years, with the widespread application of in vehicle electronic devices, driving performance as a fundamental aspect of vehicles has been continuously improved, and driving comfort and safety have also been continuously enhanced. In addition, the new generation of environmentally friendly cars adopts technologies that increase gasoline mileage and reduce carbon dioxide emissions, which has attracted widespread attention worldwide. In such a market environment, the number of electronic devices installed in limited spaces is constantly increasing, and the market's demand for in vehicle electronics is also tending towards miniaturization, resulting in a growing need to save space.diode

To meet these market demands, TDK has reduced the gap between ceramic dielectric layers by 40% compared to previous products, leveraging its advantages in material technology and stacking technology. In addition, the sintering conditions were optimized to achieve small component size and high capacity while maintaining the reliability of laminated ceramic surface mount capacitors for vehicle use.

Compared with TDK's previous products, the size of laminated ceramic surface mount capacitors for medium voltage is reduced by nearly 50% under the same capacitance conditions, while the capacitance of components of the same size is doubled compared to before. This product complies with the X7S temperature characteristics (operating temperature range: -55 ° C to 125 ° C; capacitance variation: ± 22%), making it highly suitable for use in automotive engine components and industrial equipment for AC circuit 1 switching power supplies | regulators..diode
