Advances in multi-layer ceramic capacitor (MLCC) manufacturing have led to significant improvements in the voltage and capacitance capabilities of miniature case size capacitors. These advances have extended to ceramic discoidal capacitors, which are employed in most bulkhead-mounted EMI suppression filters. They are now available in smaller packages and make the control of EMI in space- and weight-constrained aerospace applications easier and more reliable. Currently, discoidal capacitors can be manufactured with outer diameters as small as 0.050” with as much as 5,000pF of capacitance. They also have equivalent models, which helps ensure effective…
