Film Capacitors: QXK2G473KTP7ZHFL Application Field and Working Principle

Film capacitors are non-polar, low-profile, surface-mountable capacitors featuring high temperature stability and reliability over extended temperature ranges. The wide range of film capacitors available on the market makes them suitable for use in a variety of applications. In this article, we\'ll discuss the QXK2G473KTP7ZHFL film capacitor application field and working principle.

The QXK2G473KTP7ZHFL film capacitor is a low-ESR (equivalent series resistance), high-performance type film capacitor featuring extended temperature range operation. This particular series of capacitors is designed for high temperature operation up to 125°C and an extended voltage range up to 1.3 KV. With a low ESR, these film capacitors are ideally suited for applications requiring a stable and reliable capacitor solution over high temperature and voltage ranges.

In terms of application fields, the QXK2G473KTP7ZHFL film capacitors are widely used across various industries due to their extended temperature range and high performance characteristics. These film capacitors can be found in a variety of audio, automotive, and lighting applications. Examples of applications in which these capacitors are often used include power supplies, LED lighting, driver circuits, audio filters, and power inverters. In addition, these capacitors may also be used in telecom/industrial systems, instrumentation, and motor control systems.

In terms of working principle, these film capacitors are based on a thin foil construction. The two plates of the capacitor are metalised layers of thin sheeted aluminum with a thin polyester film in between. As the electric field is concentrated between the aluminum layers, the capacitor has high insulation, low leakage, and low ESR value. The capacitance also remains stable over the operating temperature range due to the uniform film between the metalized layers. Thus, the QXK2G473KTP7ZHFL film capacitor provides a stable and reliable solution for a variety of high temperature and voltage applications.

In conclusion, the QXK2G473KTP7ZHFL film capacitor has many advantages over other types of capacitors making it suitable for use in a wide range of applications across industries. These include applications in power supplies, LED lighting, audio filters, power inverters, telecom/industrial systems, instrumentation, and motor control systems. The capacitor’s working principle is based on a thin foil construction, with highly stable capacitance over varying temperatures due to the thin polyester film sandwiched between the metalized layers of aluminum. With its low ESR and extended temperature range, the QXK2G473KTP7ZHFL film capacitor provides a reliable and practical solution for many types of applications.
