DLA 13008 Guide for Conformal Coated Tantalum Capacitors 3

Tantalum capacitors contain liquid or solid electrolytes. A dry material (manganese dioxide) in solid electrolyte capacitors forms the cathode plate. Tantalum lead is embedded or welded onto the core block, which is then connected to the terminal or lead in sequence. The drawings show the construction details of the surface installation type of tantalum capacitors shown in this catalog.diode

Solid electrolyte tantalum capacitors contain manganese dioxide, which is formed on the dielectric layer of tantalum pentoxide by impregnating pellets with manganese solution and nitrate. Then heat the granular manganese nitrate in the oven to convert it into manganese dioxide. Next, the ball is coated with graphite, followed by a layer of metallic silver that provides a conductive surface between the ball and the can. After assembly, test and inspect the capacitors to ensure long lifespan and reliability. It provides excellent reliability and high stability of consumer and commercial electronic products, adding the feature of low cost. The surface installationdiode design of solid tantalum capacitors includes lead frame or lead frameless design, as shown in the attached figure. All considerations for designing tantalum capacitors: Solid electrolyte design is the cheapest under given conditions and is used in many applications. For a given capacitor unit, small size is important. They can typically withstand approximately 10% of the rated reverse DC operating voltage. It is also important whether their low-temperature performance is good or not. They do not contain corrosive electrolytes. Vishay Sprague obtained the original solid electrolyte patent and was first listed in 1956. Weishi Semiconductor Sprague maintains its leading position in this field with the widest range of tantalum capacitors. The data covers various types and styles of Vishay bed sheets for consumer and entertainment use. The detailed performance characteristics of Sprague capacitors for electronic, industrial, and military applications must be clearly defined.diode
