Various techniques and dielectric materials enhance capacitor voltage handling capabilities: Thick dielectrics withstand higher voltages, but reduce capacitance density. High purity, low defect solid dielectrics like diamond have excellent strength. Polymer impregnation fills voids within film or ceramic dielectrics.
In the worst-case scenario, the capacitor could fail catastrophically, leading to safety hazards or permanent damage to the system. Always ensure the capacitor voltage matches or exceeds the expected working voltage of the application to avoid such risks. Is it okay to use a capacitor with a higher voltage rating than required?
