Film Capacitors

Film capacitors, also known as film dielectric capacitors, plastic film capacitors or film-foil capacitors, are a particular type of capacitor that utilizes a film as the dielectric instead of the more commonly employed paper, ceramic, mica or electrolytic substances. They are considered non-polarized capacitors and typically have a cylindrical body with the positive and negative contacts attached at opposite ends. The body contains a film dielectric, which is made of either polyester, polypropylene, polycarbonate, polyphenylene sulfide (PPS), or polyphenylene oxide (PPO).

B32674D1405K000 is a film capacitor manufactured by EPCOS, a subsidiary of TDK Corp. This particular model belongs to the B32S series of film capacitors, and features an ESR value of 0.14 ohms, an inductance of 0.56µH, a capacitance of 10nF (10µF), and an insulation resistance of 3000M Ω (mega-ohm). It also has an operating temperature range of -55°C to +105°C.

Application Field of the B32674D1405K000

The B32674D1405K000 is suitable for a number of challenging and demanding electrical applications, such as in fuel systems, airbag systems, anti-lock break systems and anti-theft security systems used in modern vehicles. It has a high operating temperature range, making it suitable for high-voltage automotive applications as well. It can also be used to various power supplies and across AGS (alternator stator) windings in automotive applications. This model is also capable of providing a high capacitance stability over a wide temperature range and can handle a high overload current without the risk of distorting the waveform.

B32674D1405K000 Working Principle

The working principle of a film capacitor is based on its structure, in which two metallic electrodes are placed on either side of a thin plastic or paper dielectric. As voltage or electrical charge is applied, electric field lines are generated, which cause the electrons in the capacitor to move, thus creating an electric charge. This charge is stored between the two electrodes and can be discharged when the voltage is removed, or when the terminals of the capacitor are connected to a circuit or load. As the charge is stored, the capacitance of the film capacitor increases proportionally. The capacitance of the B32674D1405K000 can reach up to 10µF at a temperature range of -40°C to +105°C, making it suitable for a number of applications.

The B32674D1405K000 is an excellent choice for a number of high-voltage automotive applications, due to its ability to withstand high overload current without distorting the waveform, and providing a high capacitance stability over a wide temperature range. Its ESR value of 0.14 ohms and inductance of 0.56µH make it particularly suitable for fuel systems, airbag systems, anti-lock break systems and anti-theft security systems.
