Film capacitors are passive electronic devices that store energy in an electric field. They are also known as dielectric capacitors, ceramic capacitors, and film capacitors. Film capacitors are divided into two main categories: Mylar capacitors and polyester capacitors. The 171684K400Q-F film capacitor belongs to the Mylar category.

Applications

The 171684K400Q-F is a surface mount capacitor with a very small footprint and low profile. It is ideal for applications where space is a premium as it takes up very little board space. It also has a high capacitance density of 465pF/mm³, making it one of the highest capacitance density capacitors on the market. It is commonly used in medical electronics, automotive electronics, audio electronics, and power electronics. In particular, it is often used in applications requiring high ripple current, high current capabilities, and high voltage. It is also widely used in high-frequency circuits, such as filters and pulse generators.

Working Principle

A traditional capacitor works by storing static electricity between two conducting plates. When an electric current is applied to the plates, electrons move from one plate to the other, creating an electric field. The 171684K400Q-F film capacitor works by a similar principle. Two metal electrodes are sandwiched between a thin film of Mylar. This film acts as a dielectric, and when a voltage is applied, electrons move from one electrode to the other, creating an electrical field.

The Mylar film has a much higher dielectric constant than the paper or plastics used in traditional capacitors. This means that it can store more charge, and can handle higher voltages. It is also able to provide very accurate and stable capacitance values. Finally, the thinness of the Mylar film makes it one of the most space-efficient capacitors available.

Conclusion

The 171684K400Q-F film capacitor is an ideal choice for applications where space is a premium and high voltages or current capabilities are required. Its thin Mylar film creates an extremely space-efficient capacitor with a high capacitance density. Additionally, its accuracy and stability make it a great choice for high-frequency circuits and other sensitive applications.
