KEMET introduces high temperature high power DC bus thin film capacitor

     Yageo's global leading supplier of electronic components, KEMET, now announces the launch of its new C4AK high temperature high power DC bus thin film capacitor, which is designed for continuous operation at 135 ° C for up to 1,000 hours. The C4AK series combines the advantages of the C4AU (harsh environment) and C4AQ-P (125 ° C) series high-power DC bus film capacitors. The series has higher capacitance density, DC voltage and resistance to DC ripple current, and provides longer service life in harsh high-temperature environments. Ideal for automotive, green and industrial applications, this metallized film capacitor is ideal for implementing DC filtering and DC busbars in solar, fuel cells, inverters, energy storage systems, automotive (bi-directional) on-board chargers, wireless power transmission (WPT), DC/DC, heaters and welding equipment.

     The growing demand for electric vehicles and base stations, as well as technological advances in charging stations powered by renewable energy, require electronic components to be miniaturized and lightweight, with high dielectric capacitance and high heat resistance, to meet the requirements for extended operating ranges. In addition, capacitors for converters and motor driven inverters require higher guarantees of high temperature performance than ever before. The new series comes at a time when electric vehicle technology is advancing at a rapid pace. According to a report by Precedence Research, the global electric vehicle market is expected to grow at a compound annual growth rate (CAGR) of 40.7% from 2020 to 2027. 

     Kimi Electronics' DC bus C4AK film capacitors offer an excellent alternative to current capacitor solutions due to their enhanced performance design. Design features include a radial box shape suitable for PCB mounting, miniaturization, ultra-thin form, 2 to 4 leads, and fewer capacitors required to be connected in parallel to meet peak and ripple current requirements. The performance of C4AK film capacitors under harsh temperature and humidity conditions exceeds the extreme requirements of the automotive standard (AEC-Q200) for film capacitor technology. Compared to competing technologies, the C4AK series has higher performance under harsh environmental conditions, with a service life of 4000 hours at 125 ° C and 1000 hours at 135 ° C. The extended service life of C4AK DC bus thin film capacitors at high temperatures compared to conventional thin film capacitors, especially in wide band gap high frequency and high current systems, provides designers with an ideal solution for miniaturization and reducing the number of components.
