1523059 Capacitors SPRAGUE ELECTRIC CO 20 Aug 1976 [21 Aug 1975] 34891/76 Heading H1M In a ceramic disc capacitor at least one electrode layer 16 is partially covered with a layer 20 of insulating abrasive material and leads 24, 25 are soldered to the uncoated portions of the electrodes, the capacitance being adjusted by air-abrasion of a portion 30 of layer 20 and the underlying electrode layer. As shown, layer 20 is annular and overlaps the edge of electrode layer 16. |
