No Change in Capacitance Due to DC Bias

• Ceramic X7R experiences reduced capacitance due to applied bias voltage.

→Film capacitor does not experience a reduction of capacitance.

No Noise

• In some cases, a noise is generated (piezoelectric effect) when Ceramic X7R is used in AC circuits.

→Use of a film capacitor prevents noise.
