Abstract
A feed-through capacitor in which a composite dielectric layer made of a mixed material containing a resin material and dielectric material powder is arranged between a feedthrough terminal and an outer electrode terminal surrounding this feedthrough terminal, a capacitance being formed between the feedthrough terminal and the outer electrode terminal.
Claims26
A feed-through capacitor comprising:
- at least one feedthrough terminal;
- an outer electrode terminal arranged so as to surround said feedthrough terminal;
- and
- a composite dielectric layer provided in at least a region between said feedthrough terminal and said outer electrode terminal and made of mixed material containing a resin material and a dielectric powder, said capacitor being formed by said feedthrough terminal, said outer electrode and said composite dielectric.
A method of fabricating a feedthrough capacitor, comprising the steps of:
- preparing at least one feed-through terminal and an outer electrode terminal of such size that the feedthrough terminal can be inserted into the interior thereof;
- arranging said feedthrough terminal within said outer electrode terminal so as not to come into contact with the outer electrode terminal;
- and
- filling a mixed material continuing a resin material and a dielectric powder into the space between said outer electrode terminal and said feedthrough terminal in a molten state and solidifying the same to form a composite dielectric layer to serve as the dielectric for said feed-through capacitor.
A feed-through capacitor comprising:
- at least one feed-through terminal;
- an outer electrode terminal made of a tubular conductive member arranged so as to surround said feed-through terminal;
- and
- a composite dielectric layer made of a mixed material containing a resin material and a dielectric powder surrounding the feed-through terminal and inside of the outer electrode terminal, said composite dielectric layer being formed by insertion-molding and extending outside of said outer electrode terminal, said outer electrode terminal being embedded in the composite dielectric layer.
A feed-through capacitor comprising:
- at least one feedthrough terminal;
- an outer electrode terminal made of a tubular conductive member arranged so as to surround said feedthrough terminal;
- and
- a composite dielectric layer provided in at least a region between said feedthrough terminal and said outer electrode terminal and made of a mixed material containing the resin material and a dielectric powder.
