Feed Through CapacitorsFeed through capacitors are a type of capacitor that is commonly used in EMI (electromagnetic interference) optimization in cables. A feed through capacitor is a capacitor that is installed directly in the cable itself, rather than being placed externally on the cable. This allows the capacitor to provide EMI protection for the entire length of the cable, rather than just at specific points. Feed through capacitors are typically made from ceramic materials and have a high capacitance value, which allows them to effectively block unwanted electromagnetic signals from interfering with the signals carried by the cable.
