KEMET ADVANCES HYBRID ALUMINUM POLYMER CAPACITOR TECHNOLOGY

KEMET, a subsidiary of Yageo Corporation (“Yageo”) (TAIEX: 2327) and leading global supplier of electronic components, announces the launch of three hybrid aluminum polymer capacitor series: A780, PHA225, and PHH225. These AEC-Q200 qualified capacitors offer a combination of highly conductive polymer technology and liquid electrolytic material in a hybrid design, resulting in an outstanding electrical performance for automotive and industrial applications. This launch aligns with the growing vehicle electrification product market, driven in part by a rising need for 48V architecture in mild hybrid electric vehicles (MHEV). According to a September 2020 report by Markets and Markets, the vehicle electrification market is projected to grow at a CAGR of 11.9% to reach USD $129.6 billion by 2025 from USD $73.7 billion.*

The A780 series is KEMET’s first release of a 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 combined, provide greater advantages such as a higher ripple current, lower equivalent series resistance (ESR), lower leakage current, and exceptional self-healing capability than standard solid polymer aluminum capacitors with no liquid electrolyte. These capacitors can withstand heavy vibrations (up to 30g), meeting the stringent design requirements for automotive powertrain and industrial applications, including engine control units, DC/DC converters, 48V inverters for MHEV, switched-mode power supply (SMPS), and computer voltage regulator modules (VRM).

Further advancing hybrid aluminum polymer capacitor technology, the PHA225 and PHH225 with an axial and radial crown design also offer the same combination of highly conductive polymer and liquid electrolytic material as the A780 series. These capacitors can withstand temperatures up to 140°C, provide extremely high ripple current capability, and self-healing performance. The hybrid construction of polymer and liquid electrolytic provides extremely low and stable ESR across all temperature ranges, thus extending its operating lifetime.
