Film Capacitors OverviewFilm capacitors are capacitor elements made of a film dielectric and two metal electrodes. The metal electrodes come in contact with the dielectric film, and the film provides the required capacitance. This type capacitor is used for a variety of applications where characteristics such as long life, stability, high insulation resistance, high rated voltage, and low volume and weight density are desired. Films used in film capacitors are of two main types: organic and inorganic. They can also have additional metal or ceramic layers. Organic film capacitors are typically made from polypropylene or polyester and are broadly used in frequency applications where the working voltage is 600VAC or lower. Inorganic film capacitors are typically made from polypropylene-imid or polyethylene-imid and are mainly used for applications requiring higher working voltages. 50ST335M5750X Application Field and Working PrincipleThe 50ST335M5750X is a 3.3KV Film Capacitor made of polypropylene-imid for use in high voltage applications. It is a shielded type capacitor, with terminals for connecting either an aluminum or copper foil shield. The capacitor has a given capacitance of 35µF and a temperature range of -55 to +125°C.The operation of the 50ST335M5750X works on the principles of dielectric strength and voltage retention characteristics. As an electric field is applied to the capacitor, the dielectric strength of the film increases until it reaches its specific breakdown voltage. This breakdown voltage determines the maximum voltage that the film can handle. The capacitor also has excellent voltage retention characteristics, which allows it to maintain its capacitance and other parameters even for very low applied voltages.Better performance is achieved in 50ST335M5750X by using larger polypropylene-imid films and adding layers such as a metal or ceramic for further insulation. This insulation layer helps to reduce leakage and dielectric absorption, and ensure reliable long-term operation. Additionally, the shield layer can be used to reduce solid electric fields, and to withstand high voltages. The 50ST335M5750X is mainly used in AC power applications, where high voltage ratings and large capacitance are necessary. Examples include power factor correction, variable speed drives, solid state relays, elevator motors, electric power equipment and other long-term high voltage applications. In conclusion, the 50ST335M5750X is an ideal choice for applications requiring reliable and long term use with high voltage and large capacitance requirements. Its combination of dielectric strength, voltage retention, and additional insulation layers means that it can offer improved performance and longer service life.
