Abstract
A power line filter for removing interference is provided which is formed on a printed circuit board which has an extended grounding area and to which are mounted parallel capacitors, a pair of line inductors and a parallel resistor. Each of the inductors is formed as multi-section coils wound on plastic bobbins and which can be machine wound and the two wound inductors are then mounted on rectangular cores of U-U or U-I-shape to form the line inductors. At least two of the capacitors are rectangular shaped and are mounted on opposite ends of the line inductors and the assembled filter is placed into a case and encapsulated through openings formed in the printed circuit board.
