1278971 Electrolytic capacitors UNION CARBIDE CORP 24 Oct 1969 [24 Oct 1968] 52166/69 Heading H1M An electrolytic capacitor suitable for mounting on a substrate 32 comprises a base of insulating material having at least two separate electrically conductive layers on a surface such that in use these willlie parallel to the substrate, at least one solid electrolyte capacitor pellet secured to the base with the cathode coating or a cathode lead in electrical contact with one conductive layer and the anode lead 14 in electrical contact with another, the conductive layers providing bonding areas, e.g. for making connection via wire 34 to chip 30. Anode lead 14 is shown encapsulated with epoxy resin 28. Several pellets may be mounted on one base (Fig. 4, not shown). The conductive layers may be electrically connected to conductive layers on the bottom of the base (Fig. 6, not shown) so that the capacitor may sit directly on conductive areas on, e.g. a printed circuit board and bonded thereto. |
