Abstract
Abstract The component has a first insulative coating forming a perimetric margin on both planar surfaces, leads are extended over the margin at an edge of the component, and a second insulative coating is disposed over the component and terminated on the margin portion under the leads such that the extended leads are noncoated. In the method, a planar component is first predipped to provide a perimetric margin, leads are then applied to the component and extended over the margin, and the unit then coated up to margin portions adjacent the leads.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
84 words
The component of claim 1 wherein said first coating encloses the edges of said body and provides a second perimetric margin enclosing an area of the other major surface, a second terminal lead is in connection to said component and extended from the enclosed area of said second surface over said second margin at said one edge, and said second insulative coating is extended around said body and terminated on the margins adjacent said one edge such that lead portions extending therefrom are noncoated.
Claim 2
Dependent Claim
44 words
The component of claim 2 wherein said component is a substantially planar capacitor, said capacitor having an electrode disposed on both planar sides thereof, and said terminal leads are disposed on said electrodes respectively and extended in substantially spaced parallel relation from said capacitor.
Claim 3
Dependent Claim
47 words
The component of claim 3 wherein said capacitor is a cylindrical disc shaped capacitor, and said second coating is terminated on the margin portions disposed between said leads, and said leads are noncoated at least beyond a line tangent to said disc portion disposed between said leads.
Claim 4
Independent Claim
77 words
A method of making an electrical component having noncoated leads comprising forming an elEctrical component having a substantially planar body, forming a margin of insulative coating around the perimeter of said body, attaching at least one lead to said component, extending said lead over said margin, forming a second coating over said component, and terminating said second coating within a margin portion adjacent said lead such that said lead is noncoated where it extends beyond said component.
Claim 5
Dependent Claim
69 words
The method of claim 5 including the step forming a similar margin on both planar surfaces of said body so as to perimetrically enclose the edge thereof, attaching a lead to each side of said component within the area enclosed by the margins, radially extending said leads in substantially close spacing from said component, and dipping said component in insulative coating material up to margin portions adjacent said body.
Claim 6
Dependent Claim
66 words
The method of claim 6 wherein said margins are applied by coating a perforated plate with said insulative material, positioning one planar surface of said component over said perforation, and perimetrically contacting a margin portion of said component to the surface of said plate surrounding said perforation to coat said margin portion, and repeating said steps to perimetrically coat the other planar surface of said component.
Claim 7
Dependent Claim
23 words
The method of claim 5 wherein said margin is applied by rotating said component with its marginal areas in contact with coating material.
