Film Capacitors

Film capacitors, also known as film dielectric capacitors, are constructed with a metalized polypropylene film as the dielectric material and are used in a wide range of applications as an alternative to the standard electrical-grade paper and impregnated paper capacitors. They are typically rated higher than their paper or impregnated paper counterparts and can be used in a variety of electronic and industrial applications.

The C4BSPBX4120ZB0J is a film capacitor commonly used in industrial, aerospace, and medical applications. This specific capacitor is designed for low impedance applications (less than 5 mΩ at 25°C) and high ripple current capabilities (up to 12.5 Amps peak). It is also rated to operate in temperatures up to 125°C.

Application Field

The C4BSPBX4120ZB0J is mainly used in power electronics and high frequency applications due to its low impedance and high ripple current capabilities. It has wide application in the aerospace, military, and medical industries where it is used in high frequency power supplies, filters, and oscillators. Its ability to handle high frequencies make it ideal for use in switching power supplies and accelerating voltage control circuits. Additionally, the C4BSPBX4120ZB0J is highly reliable and can withstand harsh vibration and shock, making it suitable for aerospace applications like satellite and spacecraft power systems.

Working Principle

The C4BSPBX4120ZB0J works on the principle of an electrolytic capacitor. It is composed of an anode and cathode, with a thin dielectric (insulating) film between them. In a polarized capacitor, electrons flow from the anode to the cathode, with the dielectric allowing the flow of current while blocking direct-current voltages. When voltage is applied to the terminals, the dielectric film changes its electrical characteristics, allowing current to flow. This phenomenon is known as dielectric polarization, and the film\'s ability to change its electrical characteristics is what allows the capacitor to store energy. This energy is released as soon as the voltage is removed, and the capacitor functions as an electronic storage device.

The C4BSPBX4120ZB0J utilizes polypropylene film as the dielectric material between the anode and cathode, giving it superior capacitance, lower impedance and high ripple current capabilities. The polypropylene film also ensures a high operating temperature, up to 125°C, making it suitable for high frequency power electronics and aerospace applications.

Conclusion

The C4BSPBX4120ZB0J is a film capacitor designed for low impedance applications and high ripple current capabilities. Its polypropylene dielectric film makes it highly reliable and suitable for high temperature and frequency operations, making it ideal for use in power electronics, aerospace, and medical applications.
