Film Capacitors

Film capacitors are types of capacitors with thin conducting metal or metalized plastic films. Typically, film capacitors have either metalized paper or plastic film as the dielectric. Film capacitors are occasionally called plastic film capacitors, after the most essential part. Film capacitors have several advantages, such as the high-frequency properties they possess,high insulation resistance, and high temperature stability and excellent reliability. Therefore, film capacitors are popularly used in many fields, such as power supplies, decoupling, interference suppression, coupling, DC-link capacitors, and many more.

The 306PHC250K is an innovative and reliable film capacitor designed by Panasonic. This product is actually a polypropylene-film-dielectric, metallized-film capacitor with non-inductively wound construction. This capacitor is non-inductive with very low ESR values, providing good safety for the device and protection from damage due to too much current. Moreover, the product meets the requirements stated in IEC 60384-14 and has various features, like the temperature coefficient rate (25-1000Hz 1kHz), ripple current rating, and long-term reliability.

The 306PHC250K capacitor is suitable for use in consumer electronics applications mainly, such as audio systems, power supplies, and other high-frequency applications. It is mainly used in power supplies and power supply filters. What’s more, due to the low dissipation factor and excellent self-healing features, it is suitable for use in power supply filters and high-frequency audio circuits in order to filter out unwanted frequencies and reduce interference.

The working principle of the 306PHC250K capacitor is based on the capacitance that develops between two conductors when an energy source is connected. The energy source applies a voltage across the two conductors, which in turn drastically increases the electric field across their surface. This electric field attracts positively and negatively-charged particles in the area between the two conductors. The resulting capacitance in the system is then determined by the relation of the charge stored on the two conductors to the capacitors designed electric field.

Thus, to sum up, the 306PHC250K is a film capacitor with non-inductively wound construction. It is mainly used in consumer electronics applications, such as audio systems and power supplies. This product meets the requirements set in IEC 60384-14 and offers excellent temperature stability, high insulation resistance, and reliability. Furthermore, its working principle is based on the capacitance that develops between two conductors when an energy source is connected.
