Research And Design Of Novel High-Capacitance Facedown Termination Tantalun Chip Capacitor

Chip tantalum capacitors with oxide manganese cathode are widely used in aerospace?advanced military equipment?computer?automobile?communications?upgrade household and electronic uipment for its high volumetric efficiency, low DCL, good temperature and frequency characteristics, high reliability and life ope rating performance.This paperresearched and designed a new type of large capacit y bottom chip tantalum capacitor which has high reliability, small size, low equi valent series resistance(ESR) and low equivalent series inductance(ESL).It has a great significance for meeting the needs of the development of the market, enh ance the market competitiveness.The main results of research institute are list in follows:(1) Designed a new structure to meet the new high-capacity bottom chip tan talum capacitor size characteristics such as high volumetric efficiency, low ESR and ESL;(2) Optimized the mature chip tantalum capacitor production technology to make it suitable for new design products manufacturing,(3) Researched structural and performance both of the newly bottom chip ta ntalum capacitor and the traditional chip tantalum capacitor.
