DCバイアスによる容量変化無し

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

 

Film capacitor does not experience a reduction of
capacitance.

うなり音が発生しない

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

 

Use of a film capacitor prevents noise.

主な用途

• Liquid Crystal Televisions & Displays • Computers
• PDA Game Devices • Game consoles • Others

 
その他の特徴

• 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.
