    Features
    Low Impedance
    •  Film capacitor has high noise absorbency due to low ESR.
    → When film capacitor is used, the capacitance can be reduced to 1/10 of that of Tantalum capacitor.
    • Measurement Circuits

    Low ESR
    •  High noise absorption is achieved due to low ESR.
    Stable Temperature Caracteristic
    •  Set circuit movements are stable due to stable temperature characteristics.
    Fast Lockup Time
    •  Reduction of lockup time is made possible due to film capacitor's low dielectric absorption.
    Low Distortion
    •  Compared to Ceramic X7R characteristics and tantalum capacitors, the distortion and noise levels are low and high sound quality of set is achieved.
    No Shock Noise
    •  Film capacitors do not generate shock noise because they do not experience piezoelectric effect.
     
     
        When mechanical shocks, such as a light tapping on the board occur, shock noise is generated.
    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.
