Introduction to Film Capacitors

Film capacitors, also known as plastic capacitors, are highly specialized capacitors made out of metallized films. They are commonly used in high-end audio equipment and in the semiconductor industry. While film capacitors are not typically used in consumer grade electronics, they are widely used in high-end audio, RF, telecom, and computer-storage systems. The 155PSB102K6J is a popular film capacitor that is used in niche applications.

What is the 155PSB102K6J?

The 155PSB102K6J is a polypropylene film capacitor designed to operate in a variety of high-frequency applications. It has a tolerance of +-1% and is rated for DC and AC operating voltages up to 150 Volts. It is a surface mount type capacitor with an epoxy resin coating for shock and vibration protection. A sleeve is also included for increased insulation and environmental protection. The cell of the 155PSB102K6J is usually a hollow cellulose paper cylinder filled with an electrolyte.

Application Field and Working Principle

The 155PSB102K6J is most commonly used to provide filtering or isolation in RF and high-frequency circuits. It can also be used for pulse suppression or high-speed switching applications. These capacitors are also often used in high-frequency switch mode power supplies (SMPS) or other demanding power conditioning applications.The working principle of a film capacitor is simple. It is based on the capacitance between two charge carrying surfaces, which are usually of conductive metal films, separated by a dielectric material. When a voltage is applied across the capacitor’s two terminals, a charge builds up on the surfaces, creating an electric field in the dielectric material between them. The amount of charge stored on the capacitor depends on the area of the capacitor plates, the distance between them, the dielectric constant of the material between them, and the applied voltage.In the case of the 155PSB102K6J, the capacitor plates are made from metallized polypropylene film and are connected to the terminals through soldering. The dielectric material between the plates is a film of polypropylene. This combination of materials gives the capacitor its excellent electrical performance, low ESR, and high operating temperature.

Conclusion

Film capacitors have become the capacitor of choice for many demanding applications. They offer excellent performance characteristics such as low ESL, high operating temperature, and low ESR. The 155PSB102K6J is a popular film capacitor that is used in niche applications such as RF, high-frequency circuits, and switch mode power supplies. Its large capacitance range and high tolerance make it a great choice for these applications.
