A capacitor and capacitor assemblies are provided, configured to prevent damage from shock and/or vibration. A capacitor assembly according to the invention comprises an anode plate having an anode plate wire extending from a surface of the anode plate. An anode wire holder is positioned around at least a portion of the anode plate wire. A wire separator comprising a channel is provided, at least a portion of the anode plate wire received within the channel. Methods of forming capacitors and capacitor assemblies are also provided.

Hermetically sealed high energy electrolytic capacitor and capacitor assemblies with improved shock and vibration performance

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 wet electrolytic surface mount capacitor has a body defining an interior area and having a fill port formed through a wall of the body. A capacitive element is positioned in an interior of the body and is isolated from the body. A surface mount anode termination is in electrical communication with the capacitive element and isolated from the body. A surface mount cathode termination is in electrical communication with the body. An electrolyte is contained in the interior area of the body, and is introduced into the interior area of the body through the fill port. A fill port plug is positioned adjacent the fill port. A fill port cover compresses the fill port plug against the fill port to seal the fill port, and may be welded in place. A method of forming the capacitor is also provided.

Methods of manufacturing a hermetically sealed wet electrolytic capacitor and a hermetically sealed wet electrolytic capacitor are described. A method of manufacturing a wet electrolytic capacitor includes forming a cathode of the capacitor by forming a case comprising a metal substrate, the metal substrate having an alloyed surface, depositing a smooth film comprising palladium and copper as a tacking layer on the alloyed surface of the metal substrate, and depositing a rough, high surface area layer on the tacking layer to achieve a high capacitance cathode. A first terminal is electrically connected to the cathode. An anode is formed. A second terminal is electrically connected to the anode. An electrolytic solution is disposed within the case, and the case is hermetically sealed.

A hermetically sealed capacitor and method of manufacturing are provided. The hermetically sealed capacitor includes an anode element having an anode wire and a feed through barrel, a cathode element, a first case portion having a first opening portion and a second case portion having a second opening portion. The first and second opening portions form an opening configured to mate with the feed through barrel. The first opening portion may include a slot portion configured to receive the feed through barrel. The hermetically sealed capacitor may also include electrolytic solution disposed between the first and second case portions.

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 ().
