Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
A capacitor having a rectangular ceramic body with upper, lower and side edges extending between front and back faces, a plurality of electrodes embedded in the body, adjacent electrodes being separated from each other by ceramic, alternate of the electrodes having extensions to one side edge of the body and the remaining electrodes having extensions to the other side edge of the body, spaced leads generally parallel to each other with upper ends respectively secured to opposite side edges and connected to the adjacent electrode extensions and with lower ends extending below said lower edge, and an insulating coating on the capacitor enclosing the portion of the body and leads above said lower edge, at least one side edge of the body being recessed inward adjacent said lower edge so the coating surrounds the lead adjacent said lower edge of the body.
Claim 2
Dependent Claim
142 words
A capacitor having a rectangular ceramic body with upper, lower and side edges extending between front and back faces, a plurality of electrodes embedded in the body, adjacent electrodes being separated from each other by ceramic, alternate of the electrodes having extensions to one side edge of the body and the remaining electrodes having extensions to the other side edge of the body, spaced leads generally parallel to each other with upper ends respectively secured to opposite side edges and connected to the adjacent electrode extensions and with lower ends extending below said lower edge, and an insulating coating on the capacitor enclosing the portion of the body and leads above said lower edge, at least one side edge of the body being recessed inward adjacent said lower edge so the coating surrounds the lead adjacent said lower edge of the body.
Claim 3
Dependent Claim
38 words
The combination of claim 1 in which at least one side edge of the body has an inwardly and downwardly inclined bevel intersecting the lower edge and the insulating coating covers the bevel and surrounds the adjacent lead.
Claim 4
Dependent Claim
110 words
A capacitor having a rectangular ceramic body with upper, lower and side edges extending between front and back faces, a plurality of electrodes embedded in the body, adjacent electrodes being separated from each other by ceramic, alternate of the electrodes having extensions to one side edge of the body and the remaining electrodes having extensions to the other side edge of the body, spaced leads generally parallel to each other with upper ends respectively secured to opposite side edges and connected to the adjacent electrode extensions and with lower ends extending below said lower edge, said body having outwardly extending shoulders against which the upper ends of the leads abut.
Claim 5
Dependent Claim
110 words
A capacitor having a rectangular ceramic body with upper, lower and side edges extending between front and back faces, a plurality of electrodes embedded in the body, adjacent electrodes being separated from each other by ceramic, alternate of the electrodes having extensions to one side edge of the body and the remaining electrodes having extensions to the other side edge of the body, spaced leads generally parallel to each other with upper ends respectively secured to opposite side edges and connected to the adjacent electrode extensions and with lower ends extending below said lower edge, said body having outwardly extending shoulders against which the upper ends of the leads abut.
Claim 6
Dependent Claim
179 words
In combination, a capacitor having a plurality of superposed generally rectangular layers of ceramic sintered into a unitary rectangular ceramic body with upper, lower and side edges extending between front and back faces, a plurality of electrodes embedded in the body, adjacent electrodes being separated from each other by a layer of ceramic, alternate of the electrodes having extensions to one side edge of the body and the remaining electrodes having extensions to the other side edge of the body, spaced leads generally parallel to each other with upper ends respectively secured to opposite side edges and connected to the adjacent electrode extensions and with lower ends extending below the lower edge, said layers having integral superposed projections sintered into unitary standoff feet integral with said body and projecting downwardly from said lower edge between the leads, said feet being adapted to support the capacitor above a supporting surface, and an insulating coating on the capacitor enclosing the poRtion of the body and leads above the feet whereby the leads are free of insulation which would interfere with soldering.
Claim 7
Dependent Claim
179 words
