A hermetically sealed polymer capacitor and a method of forming the same are disclosed. The method preferably includes dispensing an amount of conductive paste inside a case and inserting one or more capacitor elements into the conductive paste. The conductive paste may surround sides of the one or more capacitor elements. Optionally, a bushing may be placed on the one or more capacitor elements. The bushing may have one or more holes that allow one or more positive leads coupled to the one or more capacitor elements to pass through. A cover is preferably welded to the opening of the case. The capacitor assembly is preferably dried to evacuate moisture from inside the case. The one or more positive leads are preferably welded to one or more metal tubes of a glass to metal seal (GTMS) in the cover to seal the capacitor assembly.

Disclosed are tantalum capacitors having enhanced volumetric efficiency, effective series resistance, effective series inductance, and high frequency performance when compared to existing tantalum capacitors. Also disclosed is a screening process for tantalum capacitors to enhance reliability.

High performance and reliability solid electrolytic tantalum capacitors and screening method

A surface mount capacitor () and method for making the same. A solid slug or pellet anode body () is encapsulated in a case () of insulating material. An anode and cathode termination pair () are formed with surface mount mounting portions on one side of the case (). An electrical connection () is made from the cathode termination () to a cathode on pellet () through the case (). An electrical connection () is made between an anode associated with the pellet () and the anode termination () externally of the case (). The external connection () allows improved volumetric efficiency by freeing up space in the case () for a bigger pellet (). The method includes mass producing these capacitors () by mounting a plurality of pellets () on a lead frame () with pre-formed anode/cathode termination pairs (), at least substantially encapsulating the plurality of mounted pellets () and each pellet's associated anode and cathode, singulating the encapsulated pellets () to expose a portion of the pellet anode, and applying the electrical external conductive path () between pellet anode and anode termination ().
