【摘要】 叙述了全钽全密封液体钽电解电容器的结构和特点,较之银外壳液体钽电解电容器,它克服了漏液、瞬时开路、电参数恶化与银离子迁移等缺点,因而具有性能稳定、承受纹波电流能力强、可靠性高等优点,享有"永不失效"的电容器之称。更多还原

【Abstract】 Given were the structure and characteristic of all-tantalum wet electrolytic capacitor with all-sealing structure.From the difference between wet electrolytic capacitor with silver crust and tantalum crust,analysis shows that all-tantalum wet electrolytic capacitor with all-sealing structure can overcome many shortcomings existed in common wet electrolytic capacitor with silver crust,such as electrolyte leakage,instantaneous open circuit,electrical parameter worsening,silver ionic migration and so on.Hence,all-tantalum wet electrolytic capacitors with all-sealing structure have high reliability,steady performance and strong resistance to ripple electric current,and are reputed for"never disabled capacitor".更多还原
