E01 / E07 ‘C’ Filter EMI Chips
Also known as 3-terminal chips, these use conventional MLCC manufacturing techniques to form a filter which is short circuit end-to-end and has a capacitance between the end terminals and the side (ground) terminals. The signal is carried through the internal electrodes. The current carrying capacity is defined by the cross section and number of the electrodes in the filter and is therefore linked with the capacitance of the filter. Compared to conventional 2-terminal MLCC devices the internal inductance between line and ground is reduced, giving improved attenuation.
