CA Series Inline Mega-Capacitor

TDK CA series mega-cap stacks up to three MLCCs horizontally, offering higher capacitance in a single component. The CA series utilizes a clamp and solder configuration, allowing for higher soldering temperature (for example, +260°C lead-free) soldering capability. The lead frame keeps the same stress absorption capability as the traditional CKG series mega-cap, however, the CA series uses an improved lead frame material composition to further reduce the ESR and ESL. This allows for higher ripple current capability and a reduction of overshoot/undershoot in high-speed switching applications.

The CA series mega-cap is a perfect candidate for high-power applications in both the industrial and automotive sectors because it offers supreme reliability in such harsh environments. Typical applications are xEV DC/DC converters, inverters, OBC, 48 V systems, electrical turbos, wireless charging systems, and electrical pumps. There has been significant progress in the development of automobiles with electric powertrains such as hybrid- (HEVs) and battery-electric vehicles (BEVs), and the development of highly efficient charging technologies. Both are helping to reduce greenhouse gas emissions. In such applications, the power consumption of various subsystems including inverters, onboard chargers (OBCs), and wireless power transfer (WPT) systems is increasing, and MLCCs must handle high currents and have large capacitance. For this, TDK provides an extensive lineup including 99 nF/1,000 V with a Class 1 dielectric and 47 μF/100 V with a Class 2 dielectric.
