Film Capacitors

Film capacitors, also known as film dielectric capacitors or plastic film capacitors, are capacitors that use a thin plastic film as the dielectric. These capacitors offer several advantages over ceramic and electrolytic capacitors, such as low loss, wide temperature range, high insulation resistance, and low cost.

BFC238041912 film capacitors are a type of electrolytic capacitors designed for use in high-frequency applications such as TVs, computers, and audio equipment. These capacitors have a very low impedance, making them ideal for power supply and power filter circuits.

Application Field

BFC238041912 film capacitors are often used in power circuits, such as switching power supply, motor drive, and DC/DC converter circuits. They are also used in noise suppression, high-frequency filtering, and signal harmonic suppression. These capacitors are also used in audio and video signal processing and noise reduction.

BFC238041912 film capacitors can also be used in EMI/RFI filtering applications. They are used to reduce interference, prevent crosstalk, and improve signal integrity in electronic circuits. They are also used in automotive and industrial applications for power conditioning and noise reduction.

Working Principle

BFC238041912 film capacitors work by storing an electrical charge on a thin plastic film. When a voltage is applied, the two metal plates on either side of the film develop a charge that creates a capacitor. The capacitance depends on the thickness and dielectric constant of the film.

When capacitors are connected in series or parallel, the capacitance of the individual capacitors can be combined to create a total capacitance. This is done by adding the individual capacitances in series or multiplying them in parallel. This can be used to increase or decrease the total capacitance, depending on the application requirements.

BFC238041912 film capacitors have excellent temperature stability and can operate over a wide temperature range. They have low loss, high insulation resistance, low inductance, and uniform characteristics. This makes them ideal for high-frequency applications.

BFC238041912 film capacitors are relatively easy to install and can be mounted on heat sinks or circuit boards for maximum heat dissipation. They are also relatively inexpensive and require little maintenance.
