TDK Corporation has extended the automotive-grade CA Series of its MEGACAP MLCCs with metal frame. Mass production of the product series began in September 2024.

In recent years, the development of automobiles with electric powertrains, such as hybrid- (HEVs) and battery-electric vehicles (BEVs), and highly efficient charging technologies, has significantly progressed. Mainly, both help to reduce greenhouse gas emissions. In these applications, the power consumption of various subsystems, including inverters, onboard chargers (OBCs), and wireless power transfer (WPT) systems is increasing. Thus, MLCCs must handle high currents and have large capacitance.

To meet these needs, TDK developed the CA Series, the largest MLCCs in the industry* (6.00×5.60×6.40mm) with a metal frame and 3-line type structure. Now, it provides an extensive lineup, including 99nF/1000V with a Class 1 dielectric and 47μF/100V with a Class 2 dielectric.

Moreover, to handle high currents, TDK has reduced the equivalent series resistance (ESR) compared to the previous products. To this end, it is optimized the materials of the metal frame. Accordingly, this helps reduce the number of components and miniaturizes devices. Further, TDK will expand its lineup to meet the needs of customers.

Specifically, the new CA Series of MLCCs suits applications for smoothing and decoupling of the power lines, resonant circuits in subsystems such as OBCs and WPTs and snubber circuits in inverters.
