Abstract
A passive low pass, &pgr;-type filter of a surface mounted device configuration has two stack capacitors disposed radially inwardly of a coil, otherwise known as an inductor. Each capacitor has a number of ground plates successively stacked between a number of signal plates. The ground plates electrically engage a front and rear ground band which circles the external surface of a non-conductive encapsulant of the filter. A forward and rearward conductive member or sheet engages each end of the encapsulant. One end of the coil is engaged to the front sheet and the opposite end is engaged to the rear sheet. The signal plates of the forward capacitor are engaged to the front sheet and the signal plates of the rearward capacitor are engaged electrically to the rear sheet.
