Ceramic capacitor filtering

Recently, designers have found a different reason for considering ceramic capacitors for filtering—a shortage of tantalum capacitors. Unfortunately, using ceramic capacitors for input filtering can cause problems. Applying a voltage step to a ceramic capacitor causes a large current surge that stores energy in the power-lead inductances.
