NB: [[wikipedia:Capacitor types#Class X and Class Y capacitors|Class X and Class Y]] refers to safety certifications. | |||
Class X are for use where their failure would not present an electric shock risk but could result in a fire, such as a filter capacitor connected across the AC mains. Class Y are rated for use where their failure would present an electric shock risk, such as filter capacitors connected from the AC line to protective earth (PE). | |||
Various subclasses (X1, X2 ...) define peak service voltages. | |||
