Film capacitors are capacitor components made of thin plastic film as the dielectric material. The dielectric material is a polyester or polyamide film, characterized by thin and light, small volume, small roll resistance, high stability and good high frequency characteristics. The C4AQUBU4330A11J is one of these capacitors with a variety of applications and a relatively simple working principle.

Application Field

The C4AQUBU4330A11J, being a film capacitor, is able to filter noise at high frequencies, provide steady voltage and protect the circuit from power surges in applications like distributing electricity, UPS system, telecommunication, medical equipment, power transformers and so on.

Working Principle

In terms of working principle, the C4AQUBU4330A11J is a classic capacitor, defined by two conductive surfaces separated by a thin dielectric material. They store electrical energy by means of a dielectric medium: when voltage is applied across the two plates, an electrical field is generated and the electrons move to the plate with opposite polarity. This movement stores energy in the form of electric charge.

The C4AQUBU4330A11J has low dielectric absorption, improved insulation properties, and excellent electrical properties such as high ripple current capacity and low ESR (Equivalent Series Resistance). When using these capacitors in high voltage applications, the gap should remain within band and the dielectric absorption should remain within 100% of the rated capacitance.

In operation, when the circuit turns off and the voltage across the capacitor drops, the electric field maintains and starts to dissipate the energy by energizing components around. This process is known as “capacitor discharge”.

Film capacitors are also highly effective energy savers. They work in a wide temperature range and use high impedance to reduce the energy needed by the connected circuit. This helps the connected circuit to run under its maximum efficiency.

The C4AQUBU4330A11J is a robust and reliable film capacitor that offers an economical solution for power usage. They have a long life and wide temperature range, making them an excellent choice for industrial applications.
