Film Capacitors

Film capacitors, or film-dielectric capacitors, are one of the most commonly used types of capacitors, due to their excellent electrical characteristics, wide temperature range, low cost and reliable performance. The B32559C6683K289 is a type of film capacitor specifically designed for low impedance applications.

Application Field

The B32559C6683K289 is suitable for applications requiring low impedances, including power supply filters, regulator circuits, and high frequency switching/timing circuits. It is also ideal for use in low-voltage, low frequency circuits, as it exhibits low capacitance change with frequency and stable capacitance over time. The capacitor offers excellent dielectric absorption, high insulation resistance, negligible temperature drift, and low leakage current. It also offers good filtering characteristics and wide operating temperature range.

Working Principle

Film capacitors are constructed with a plastic or paper film as the dielectric layer between two metal plates, with the film providing excellent insulating and dielectric properties. Each metal plate is electrically connected to one of the capacitor’s terminals. The electrical characteristics are determined by the size and thickness of the metal plates, as well as the type and thickness of the dielectric material. When an AC voltage is applied across the capacitor, the electric field causes a charge to flow through the plates, which create a capacitance. The current flow through the plates is proportional to the voltage applied.

Conclusion

The B32559C6683K289 is an ideal choice for a variety of applications that require low impedance, quality insulation and reliable performance. This film capacitor offers excellent dielectric absorption, high insulation resistance, negligible temperature drift, and low leakage current. It is well-suited for AC signal filtering circuits, regulator circuits, and high frequency applications.
