Let’s explore their features in detail:</p><h3>Design and Construction</h3><p>The YAGEO Group AEC-Q200 Hybrid Polymer Capacitors feature a polarized, all-welded construction. The internal winding is contained within a cylindrical aluminum can, sealed with a high-purity aluminum lid and a quality rubber gasket. This design provides structural integrity and environmental protection. The winding is also impregnated with a liquid electrolyte, which facilitates self-healing capabilities in the event of dielectric breakdown.</p><h3>Electrical Characteristics</h3><p>The hybrid polymer design enables high ripple current handling and low ESR performance, ensuring electrical stability. They are suitable for use in high-temperature environments. The A787 series is notable for offering high capacitance-to-voltage (CV) ratios. The impregnated electrolyte contributes to self-healing behavior, extending performance reliability during overload or fault events.</p><h3>Mechanical and Mounting Features</h3><p>The capacitors are designed to withstand mechanical stress, offering vibration resistance up to 30g for most series and up to 20g for the PHA227 and PHH227 series. Specific variants, such as the PHH225, include a radial crown feature, which allows for vertical mounting in a standing position. The PHA223, PHH223, PHA227, and PHH227 series are available in diameters of 16.2mm, 18.2mm, and 20.2mm.</p><h3>Environmental and Reliability Characteristics</h3><p>The capacitors are qualified for AEC-Q200 compliance, making them suitable for high-reliability automotive standards. They demonstrate vibration resistance up to 20 g in PHA227/PHH227 series and up to 30 g in other variants, ensuring mechanical endurance under dynamic conditions. The devices also support high-temperature operation, maintaining consistent performance across wide environmental ranges.</p><h2>Applications</h2><p>The YAGEO Group AEC-Q200 Hybrid Polymer Capacitors are suited for environments requiring stable capacitance, high ripple current tolerance, and vibration resistance. In automotive systems, they support functions such as DC/DC converters, power control units, and onboard electronics, where low ESR and reliability are critical. Their self-healing behavior and wide –55 °C to +125 °C temperature range enable dependable use in mobile and aircraft installations, where exposure to mechanical stress and thermal fluctuations is common. The combination of compact cylindrical packaging, axial or radial crown mounting, and vibration resistance up to 30 g makes them suitable for compact, space-constrained applications.</p>
