Film Capacitors

A film capacitor is a type of capacitor, also known as a plastic film capacitor, paper capacitor, dielectric film capacitor, film dielectric capacitor and plastic film capacitor, which uses a film as the dielectric material. Film capacitors are one of the most common types of capacitors in the market today, as they offer good performance at an affordable cost, as well as being easy to manufacture and highly reliable.

BFC241812003 application field and working principle

The BFC241812003 is a long, twin-shaped film capacitor designed for use in devices with high-density requirements. This type of capacitor is commonly used in audio-frequency, digital, and power systems, as well as in medical and industrial applications. The BFC241812003\'s working principle is based on the electrostatic properties of dielectric films, which are microscopic layers of Polyethylene Terephthalate (PET) or Polypropylene (PP) thermoplastic polymer.

When placed between two metal electrodes, the dielectric film acts as a barrier between the electrodes\' electric charge, preventing the electrons from moving. The electric charge is then stored within the capacitor in the form of an electric field. This electric field is released when the electrical contact between the two electrodes is removed, allowing electrons to flow between them.

The BFC241812003 is commonly used in high-frequency, audio-frequency, digital, and power systems, as well as in medical and industrial applications. The capacitor offers a high capacitance in a compact design and operates in a temperature range of -40 ~ +85°C. It also has an excellent high-temperature stability rating of -15 or higher. Furthermore, the capacitor has been designed to provide high reliability, with its self-healing capability and low ESR characteristics.

The most notable characteristics of the BFC241812003 are its low dissipation factor, high volumetric efficiency, and low dielectric absorption. The low dissipation factor helps ensure that the capacitor is able to perform reliably and efficiently, as it helps the capacitor to store the charge for a longer period of time. The higher volumetric efficiency makes the capacitor ideal for use in applications where space is limited, as it allows for a smaller overall size. Lastly, the capacitor has a low dielectric absorption rate, which helps reduce the input of unwanted heat.

The BFC241812003 is a reliable, efficient, and cost-effective solution for applications in which high-density requirements are a must. Its ability to operate in a temperature range of -40 to +85°C, along with its self-healing and low ESR characteristics, make it an ideal choice for a variety of applications.
