QXK2G473JTPTZH

Film capacitors, commonly known as film caps, are a type of capacitor developed in the early 20th century for use in circuits requiring highly accurate timing and current carrying capability in a compact unit. This type of capacitor is highly reliable due to the special plastic material used in the construction that has a low dielectric constant and relatively low dielectric losses. They are also well suited for use in circuits requiring high stability over wide temperature ranges and are typically used for storing energy in power supplies, frequency stabilization and dynamic braking.

QXK2G473JTPTZH Application Field and Working Principle

The QXK2G473JTPTZH film capacitor is commonly used in power supplies, frequency stabilizers and dynamic braking applications. It is designed to replace standard electrolytic and tantalum capacitors in these applications, as it offers superior performance in terms of reliability, stability, and energy storage capacity. The film capacitor utilizes a very thin polyester, polyethylene naphthalate (PEN) or polypropylene (PP) film as the dielectric, which is then encapsulated in a metal container with two metal electrodes. These electrodes are either connected in series or parallel, depending on the application.

The capacitor works in a very simple manner. When a voltage is applied across the terminals of the capacitor, a charge is created between two plates, which results in the storing of energy between them. This energy can then be discharged by releasing the voltage across the terminals. This process can be done multiple times, allowing the capacitor to be used in dynamic braking applications and frequency stabilization applications. The capacitance of the QXK2G473JTPTZH film capacitor ranges from 0.1 to 50µF and it has a maximum working voltage of 100V.

The QXK2G473JTPTZH is typically used in switched-mode power supplies, as it is highly reliable and offers excellent storage capacity. It can be used in battery-powered circuits, as the low ESR (equal series resistance) provides better circuit efficiency. It is also well suited for use in LCD TVs, computers and gaming consoles, due to its low power consumption and high energy storage capability.

In general, the QXK2G473JTPTZH film capacitor is a reliable component that offers superior performance in power supplies, frequency stabilizers and dynamic braking applications. It is capable of withstanding high temperatures and operating at wide temperature ranges, making it suitable for use in a variety of electronic devices. In addition, it is highly reliable and offers excellent storage capabilities, making it an ideal choice for those looking for an efficient and cost-effective capacitor.
