    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.

    Low Impedance
    •  Film capacitor has high noise absorbency due to low ESR.
    [Impedance Characteristics Data]
    Impedance Characteristics Data
    Stable Temperature Characteristics
    •  Set circuit movements are stable due to stable temperature characteristics.
