Film capacitors, or film dielectrics, are capacitors made of polyester (PET) or polypropylene (PP) film with metalized electrode layers located on both sides of the film. The 890303325004CS is a polyester film capacitor, which can offer up to 85V DC voltage rating. It is characterized by its low ESR and high ripple current and can withstand up to 90°C operating temperature.

The 890303325004CS is a radial leaded discrete capacitor designed for general-purpose, DC-link and AC filter applications. It is used in power and automotive electronics, where it helps to filter out high-frequency noise and improve system reliability. It is also commonly employed in control and switching electronics, telecommunications, and renewable energy systems.

A film capacitor is made of a strip of polyester or polypropylene dielectric film, which is coated with a metal electrode on each side. This creates two parallel electrical plates that are separated by the dielectric, forming a simple capacitor structure. When a voltage is applied to the capacitor terminals, electrons move from one electrode to the other, creating an electric field that stores energy in the form of electrical charge. The capacitance of the film capacitor is determined by the size of the metal electrodes and the dielectric used.

The 890303325004CS has a self-healing mechanism, meaning that in the event of an overvoltage stress, any micro-fractures in the dielectric film will be quickly repaired thanks to the self-healing layer. This leads to a longer service life and improved reliability. The capacitor has a wide operating temperature range (from -40°C to +90°C) and excellent electrical properties, making it suitable for critical applications in harsh environments.

The 890303325004CS is also highly resistant to vibration, shock and temperature cycling, making it suitable for automotive applications. Its low ESR and high ripple current capability make it an ideal choice for DC link and DC filter applications, which require suppressed noise and low power losses. It is also the perfect choice for AC filter applications, where the capacitor helps reduce noise and improves system performance.

The 890303325004CS is designed for both commercial and industrial applications and is RoHS-compliant. It is a cost-effective solution for DC link and filter applications, offering excellent electrical performance, high reliability and long-term performance. This makes the 890303325004CS the perfect choice for a wide range of applications.
