Electrolytic capacitor conductivity of metals. In 1991 Panasonic came on the market with its "SP-Cap", called polymer aluminum electrolytic capacitors. These aluminum electrolytic capacitors with polymer electrolytes reached very low ESR values directly comparable to ceramic multilayer capacitors (MLCCs). They were still less expensive than tantalum capacitors and with their flat design for laptops and cell phones competed with tantalum chip capacitors as well. Tantalum electrolytic capacitors with PPy polymer electrolyte cathode followed three years later. In 1993 NEC introduced its SMD polymer tantalum electrolytic capacitors, called "NeoCap". In 1997 Sanyo followed with the "POSCAP" polymer tantalum chips. A new conductive polymer
Electrolytic Zinc Electrolytic Zinc Electrolytic Zinc or the Electrolyic Zinc Company of Australasia (frequently abbreviated to "EZ" ) was the company that operated a Zinc refinery on the banks of the Derwent River in Risdon in Hobart in Tasmania between 1916 and 1984. The refinery was often given names such as the "Risdon works", the "Zinc works","reduction works" The current usage and place name located at the Risdon works is identified as Lutana. The operations of the Risdon works were tied in with the mining of zinc in Rosebery on the West Coast of Tasmania. The company started operation in 1916 at
