Film capacitors are essential components in today’s electronics. They are popularly used in many areas, such as audio equipment, AC/DC power supplies, resistors, and variable resistors.In order to understand its application field and functional principle, this article will introduce B32672Z5224K289, one of the most common film capacitors.

B32672Z5224K289 is a type of metallized polyethylene naphthalate (M-PEN) film capacitors. It features low equivalent series resistance (ESR) and low self-inductance. It consists of two aluminum foil electrodes which are electrically separated by a thin dielectric film of M-PEN. The electrode and dielectric materials are enclosed in a cylindrical plastic housing. These components enable the capacitor to store a large amount of electrostatic energy.

B32672Z5224K289 capacitors typically offer a rated voltage of 250V AC. The capacitance is typically between 22 and 470uF. It typically has a maximum ripple current of 790mA, a maximum operating temperature of 85°C, a maximum dissipation factor of 0.1% at 1kHz and an insulation resistance of over 5000MΩ. These parameters make the B32672Z5224K289 suitable for a variety of applications, including high voltage and low leakage current applications, such as motor control, lighting and regulators.

To understand how B32672Z5224K289 operates and how it affects the current flow, we will first discuss the working principle of film capacitors. A film capacitor is essentially a device made up of a layer of dielectric material between two electrodes. When a current is applied to the capacitor, the electric field generated between the two conductive layers causes electrons to move, creating an electric charge stored in the dielectric material. This electric charge is called the capacitance and is determined by the type of dielectric used as well as its thickness.

The current flow through the capacitor can be controlled by adjusting the capacitance. The higher the capacitance, the more current is allowed to flow through the capacitor at any given time. This is because the electric field generated between the conductive layers is stronger, so the amount of electric charge stored in the dielectric material is higher. This means that the capacitor can store more energy, which can then be released when needed.

B32672Z5224K289 has a low ESR and low self-inductance. This makes it suitable for applications where high performance is necessary, such as in switch-mode power supplies, audio amplifiers, and lighting. It is also used in applications where a high peak current is needed, such as motor control and regulators. The low ESR also helps protect the connected components from damage due to excessive current.

In summary, B32672Z5224K289 is a type of metallized polyethylene naphthalate film capacitor with a rated voltage of 250V AC. It has a low ESR and low self-inductance, which makes it suitable for high-performance applications. It is also used in applications where a high peak current is needed, such as motor control and regulators. Its operating principle is based on the ability of the capacitor to store a large amount of electrostatic energy, which can then be released when needed.
