Film Capacitors

Film capacitors are a type of capacitor with a dielectric consisting of one or more layers of thin film material. They can be used in a wide range of applications and come in various different shapes and sizes. They are also known as foil capacitors, film-foil capacitors, or polymer film capacitors. They have a number of advantages over other types of capacitors, including excellent insulation characteristics, high operating temperature, low noise, long-term stability, low voltage coefficient, and low effective series resistance (ESR).

B32560J6152K189 is one of the many different types of film capacitors available in the market today. It is constructed with a polyphenylene sulfide (PPS) film dielectric, which is a strongly insulating, thermally stable material with a high degree of strength. This type of capacitor is highly resistant to moisture, chemicals, and thermal shock, making it an ideal choice for use in a variety of automotive, industrial, and medical applications.

Application Field

B32560J6152K189 film capacitors are most often used in power supplies and other power conversion applications. They can also be used in RF circuits, high frequency power supplies, signal filtering, and signal processing designs. This type of capacitor is well-suited for use in automotive, industrial, and medical applications due to its high temperature stability, excellent resistance to moisture, chemical resistance, and long-term stability.

Working Principle

Film capacitors work in the same way as traditional electrostatic capacitors. They are made up of two electrically conductive layers separated by a dielectric. When voltage is applied to one of the layers, a static electric field is created between the two layers, which adsorbs electrons and stores electrical energy. The amount of energy stored is proportional to the total capacitance of the capacitor.

When the voltage across the capacitor is changed, the electrostatic field between the two layers also changes, resulting in a change in the electrical charge stored. This change in charge creates a new current, which is drawn from one layer of the capacitor and returned to the other. This current is then dissipated into the components of the circuit, which is why a film capacitor is also sometimes referred to as a leaky capacitor.
