‘Pi’ filters incorporate 2 capacitors and an inductor together to make a multi-element filter, giving sharper cut-off and better low frequency performance than straight ‘C’ filters. The Syfer range of SM ‘Pi’ filters use conventional MLCC manufacturing techniques to form the capacitive element of the filter, but the inductive element is created separately either by means of a bead inductor placed over a through conductor pin, or by means of a buried layer surface mount inductor with the signal carried by the buried internal layers. Current carrying capacity is defined by the characteristics of the conductor and is independent to the capacitance of the filter.
