PHH227电容器的铝-聚合物电容器规格书PDF中文资料

PHH227属于电容器的铝-聚合物电容器。由基美公司制造生产的PHH227铝 - 聚合物电容器铝聚合物电容器如所对应的标准电解电容器一样，都是具有氧化铝电介质的基于铝电极材料的极化电容器类型，但区别在于使用了导电聚合物材料而不是传统的液体电解质。相对于标准铝电解电容器，聚合物电容器往往具有更佳的电气性能，但成本更高且对工作环境的敏感性也更高。

Overview

KEMET'S PHH227 is a conductive polymer hybrid capacitor with outstanding electrical performance. These capacitors contain a radial crown, which allows them to be mounted in a standing position. The device has a polarized all-welded design, tinned copper wire leads, and a negative pole connected to the case. The PHH227 winding is housed in a cylindrical aluminum can with a high purity aluminum lid and high-quality rubber gasket. Low ESR is conditioned by a highly conductive polymer (PEDOT/PSS) and an all-welded design. The polymer system creates an electrical pathway between the anodic oxide layer and the cathode through a mechanical separator - paper. The PHH227 winding is impregnated with liquid electrolyte that results to self-healing features of the capacitor. Thanks to its mechanical robustness, the PHH227 is suitable for use in mobile, automotive and aircraft installations with operation up to +125°C.
