As a major feature of the 104PHB850K2H, it has the capability to produce power film capacitors. This type of capacitor is an ideal solution for the design of circuits that require a high level of regulation and reliability. It has a wide variety of applications, such as applications in AC power filtering, DC-DC conversion, and power factors correction. In this article, we will introduce the 104PHB850K2H, illustrate its application field and working principle, and discuss some of the advantages and the limitations of using power film capacitors.

Application Field

The 104PHB850K2H is mainly designed for applications in the automotive, instrument and control, and power electronics industries. Its application fields include AC power filtering, specific AC noise filtering, DC-DC conversion, various motor drive systems, power factor correction, EMI/RFI noise filters, and high voltage protection. Additionally, its high ripple current performances allow for the stabilization of input/output audio signals. The104PHB850K2H is also commonly found in consumer electronics, such as TV sets, audio equipment, computers, and other devices that require an AC power filter.

Working Principle

Power film capacitors use two pieces of film with different capacitor electrodes that are interleaved into a stacked dielectric, with the outer plates being either metalized aluminum or paper. The capacitor plates form a single capacitor unit that works by using an electrostatic field generated by the two plates between them. This field stores charge and creates a current, which is referred to as the voltage. As the voltage passes through the capacitor, it causes a low-impedance path. This low-impedance path allows for a higher current to flow than that of conventional parallel-plates capacitors. The 104PHB850K2K has two distinct advantages in comparison to other capacitors: high ripple current and high reliability.

Advantages of Power Film Capacitors

The first advantage of power film capacitors is their high ripple current. This type of capacitor is able to handle high ripple current levels, meaning that it is capable of regulating the power of an AC signal more efficiently than other types of capacitors. In addition, power film capacitors have a higher level of reliability due to their high voltage resistance and low leakage current. They also have a longer life when compared to other types of capacitors.

The second advantage of power film capacitors is their high capacitance value. This higher value makes them ideal for applications that require a wider spectrum of frequencies. Additionally, their smaller footprint and lightweight construction allows for a wider range of applications. As an example, power film capacitors are often used in automotive applications. Since they occupy less space, they are able to fit into tight spaces that other types of capacitors are unable to fit into.

Limitations of Power Film Capacitors

Power film capacitors are limited in their range of applications. They are not suitable for low voltage and current applications as the voltage tends to drop at low voltages. They are also not suitable for applications that require a large amount of capacitance as they may be unable to meet these demands. Additionally, power film capacitors may be prone to physical damage as they are made of thin film. Last, their higher production cost makes them less cost-efficient in comparison to other types of capacitors.

In conclusion, the 104PHB850K2H is a power film capacitor and is ideal for various applications that require a high level of regulation and reliability. Its application fields include AC power filtering, specific AC noise filtering, DC-DC conversion, various motor drive systems, power factor correction, EMI/RFI noise filters and high voltage protection. It has the advantages of a high ripple current, high reliability, and a high capacitance value, but its limitations include lower voltage performance, higher production costs, and physical susceptibility.
