B32933B3474K189 Capacitors

Film capacitors, also known as film dielectric capacitors, are widely used in the field of modern electronics. They are constructed using dielectric films, such as polyester, polypropylene, lead-sulfide and even some varieties of cellulose esters. In general, they provide higher stability and better tolerance to temperature variation than conventional ceramic capacitors. Film capacitors are often used in high-end equipment and require more precise specs, making them appear in a variety of applications. B32933B3474K189 is a 2200 microfarad 80V electrolytic capacitor that belongs to this category. This article will discuss its application field and working principle.

B32933B3474K189 is mainly used for power management and filtering applications. It’s commonly used in various electronic circuits, such as high-end audio systems, power supply circuits, and even lighting applications. The capacitor\'s high ripple current rating makes it suitable for applications with large AC input current, such as power supply circuits that have frequent and high current load changes. In addition, the capacitor\'s low ESR rating enables it to reduce impedance and noise in the circuit, providing high-quality power supply performance.

The working principle of film capacitors is similar to a conventional ceramic capacitor. It has two metal plates, separated by a thin dielectric material. When voltage is applied to the plates, an electrical field is formed. This electrical field is what allows the two plates to store opposite charges, creating a capacitance. Two factors that affect the capacitance are the shape and size of the plates, as well as the dielectric material used.

The B32933B3474K189 capacitor features an 80-volt dielectric rating and +20%/-10% tolerance. This means the actual voltage seen by the capacitor can range from 72 volts to 88 volts. It also features low ESR and a high ripple current rating of 5000 amps. The combination of these features makes this capacitors well-suited for applications such as filtering, power management, and even lighting.

In conclusion, B32933B3474K189 is a film capacitor that is widely used in power management and filtering applications. Its main features are an 80-volt dielectric rating, +20%/-10% tolerance, low ESR, and a high ripple current rating of 5000 amps. These characteristics make it suitable for applications such as lighting, high-end audio systems and power supply circuits.
