Spacers often results in contact resistance because the spacers are made of a different material. One can use the same screws for both terminals, since they have the same thread depth. The terminals can be designed with female threads or male threads. FTCAP adapts the capacity and voltage of the foil capacitors to the particular application, with standard capacities from 200 µF to 3300 µF and voltages from 700 V DC to 1500 V DC. Other capacity and voltage combinations can be implemented on request.
