Film Capacitors

Film capacitors are types of capacitors with thin layers of plastic film as dielectrics. Manufactured in a variety of different forms, film capacitors are a cost-efficient and reliable source of energy storage.

One such type of film capacitor is the 38FB4440-F. This film capacitor is used frequently in high frequency applications as well as for general purpose filtering and blocking applications. As a European standard part, it features a non-inductive construction. The capacitor body is composed of metallized polypropylene film and the voltage rating is 440VAC.

Application Field

The 38FB4440-F is suitable for a wide range of applications due to its non-inductive construction. It can be used in various device types, such as power supplies, audio amplifiers, and motor speed controllers. It is also commonly used in analog circuits, circuit protection, output filters, and use in applications involving peak voltage surges.

Due to its robust structure, the 38FB4440-F is ideal for automation applications and for applications that will be subjected to rigorous environmental conditions. It is also an excellent choice for high temperature applications.

Working Principle

The key feature of the 38FB4440-F is its non-inductive construction. This means that the capacitor does not generate electrical energy when it is connected to a power source. The non-inductive construction ensures that the capacitance value does not change significantly with changes in temperature or polarization.

When the capacitor is charged, it stores electrical energy within its dielectric layers. The stored electrical energy is then released when the voltage across the capacitor reaches its maximum rating. This ensures that the output power is reliable and consistent.

The 38FB4440-F also features a polypropylene dielectric, which ensures excellent insulation characteristics. This helps to ensure the capacitor is safe from accidental electrical shock.

Conclusion

The 38FB4440-F is a reliable and cost-efficient film capacitor, ideal for a wide range of applications. Its non-inductive construction ensures consistent performance, while its robust structure and polypropylene dielectric ensure excellent insulation characteristics.

Whether used in high frequency applications, circuit protection, or output filters, the 38FB4440-F is an excellent choice for reliable and cost-efficient energy storage.
