• Ceramic X7R experiences reduced capacitance due to applied bias voltage. →Film capacitor does not experience a reduction of capacitance. [DC Bias Characteristics Data] • In some cases, a noise is generated (piezoelectric effect) when Ceramic X7R is used in AC circuits. →Use of a film capacitor prevents noise. [Noise Measurement Data] • Film capacitor has high noise absorbency due to low ESR. [Impedance Characteristics Data] • Set circuit movements are stable due to stable temperature characteristics. [Temperature Characteristic Data] • Mobile Phones • PHS • PDAs • W-LANs • Ceramic X7R noise countermeasure • Low ESR, stable capacity 50 ~ 100VDC : 0.1µF ~ 1.0µF
