Guoju Company ("Yageo") (TAIEX: 2327), announced today the launch of three hybrid aluminum polymer capacitor series: A780, PHA225 and PHH225. These three AEC-Q200 certified capacitors combine highly conductive polymer technology with liquid electrolyte materials in a hybrid design, providing excellent electrical performance for automotive and industrial applications. The products released this time are in line with the growing market for automotive electrification products, driven in part by growing demand for 48V architectures from mild hybrid electric vehicles (MHEVs). According to a report released by market research firm Markets and Markets in September 2020, the automotive electrification market is expected to grow at a compound annual growth rate (CAGR) of 11.9%, and will grow from US$73.7 billion to US$129.6 billion by 2025. *
A780 series is Jimei Electronics' first surface-mount (V-Chip) hybrid aluminum polymer capacitor. Both liquid aluminum electrolyte and solid polymer materials are housed in a cylindrical aluminum can, and when used in combination, it has greater advantages over standard liquid electrolyte-free solid polymer aluminum capacitors, such as higher ripple current resistance, lower equivalent series resistance (ESR), lower leakage current and excellent self-recovery characteristics. These capacitors can withstand severe vibrations (up to 30g), meeting the stringent design requirements for automotive powertrains and industrial applications, including engine control units, DC/DC converters, 48V inverters for MHEVs, switching power supplies (SMPS), and computer regulator modules (VRM).
PHA225 and PHH225 hybrid aluminum polymer capacitor technology has achieved further development, with axial and radial crown-shaped designs, which are the same as the A780 series, and also combine highly conductive polymers with liquid electrolyte materials. These capacitors can withstand temperatures up to 140°C, providing extremely high anti-ripples current capability and self-recovery characteristics. The hybrid structure of polymer and liquid electrolyte provides extremely low and stable ESR in all temperature ranges, thus extending its service life.
PHA/PHH 225 capacitors are smaller in size and have higher ripple current resistance per unit volume, so it is very useful to use it to design automotive and industrial technologies such as 48V automotive inverters. When designing existing 48V automotive inverters, if multiple smaller high-power density hybrid aluminum capacitors are used in parallel, the number of required components can be reduced and the ripple current resistance can be maintained. The PHA225 and PHH225 hybrid series are ideal for designing high-power automotive applications such as DC buses for 48V inverters, cooling fans, water pumps, power steering, and braking and injection systems.
"The design of the A780, PHA225 and PHH225 series combines Kime Electronics' proprietary hybrid polymer technology with electrolyte materials." Rui Monteiro, Director of Alcohol Electrolytics, said, "These advances in polymer and aluminum products not only support the growing trend in automotive electrification, but also provide reliable solutions for design engineers in decoupling, smoothing, filtering and power conversion." The
A780, PHA225 and PHH225 series are now available for purchase immediately through Kime Electronics' distributors.
