Figure 5 illustrates typical capacitance change versus AC voltage of a Class-II capacitor. Figure 6 illustrates typical capacitance change versus DC voltage on a 16VDC-rated part. Based on the plots in Figures 5 and 6, it is important to note that AC and DC applied voltages must be considered when measuring capacitance.
Safety Capacitors First: Class-X and Class-Y Capacitors
When a Class-X capacitor, also referred to as an "across the line capacitor"—the capacitor placed between line and neutral—fails because of an overvoltage event, it is likely to fail short. This failure, in turn, would cause an overcurrent protective device, like a fuse or circuit breaker, to open.
