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。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”.
