• 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] • Liquid Crystal Televisions & Displays • Computers • PDA Game Devices • Game consoles • Others • Ceramic X7R noise countermeasure • No reduction of capacitance when DC bias is applied. → By the differential of DC bias characteristics, the capacitor's total capacitance is reduced to less than 40% of Ceramic X7R's. 16V : 104～105
