Introduction

Film capacitors, also known as film dielectric capacitors, are passive electrical components that store electrical energy. They are mainly used in electronics and electrical equipment, where they serve the purpose of filtering, timing and decoupling, just to name a few. They are built using a dielectric film as the dielectric material and are classified depending on their construction, materials used, and end uses. This article is about the QXK2J154KTP, one of the many film capacitors available for purchase. It will discuss the application field and working principle of the QXK2J154KTP.

Application Field of QXK2J154KTP

The QXK2J154KTP is a polypropylene non-polar film capacitor with a bipolar rated voltage of 630V. It has a capacitance range of 100 to 680nF, and a tolerance range of ±0.5%. As it is non-polar, it can be used in AC applications, making it suitable for AC voltage dividers, coupling applications, and filters. Furthermore, the QXK2J154KTP can also be used in DC applications, making it suitable for power shunts, capacitive dropping resistors, and switching power supply filters.

Working Principle of QXK2J154KTP

The working principle of film capacitors is fairly simple. In these capacitors, a thin dielectric film is sandwiched between two electrodes. When a voltage is applied across these two electrodes, the dielectric film creates an electric field within the film and produces a capacitance, which is the ability of the capacitor to store electric charge. This stored electric charge allows the capacitor to act as an electrical filter or a voltage control device.

The QXK2J154KTP film capacitor is non-polar, meaning that the same voltage can be applied to either of the two electrodes. As the capacitor is made from polypropylene, it exhibits a high dielectric strength and good capacitance retention over temperature and frequency. Additionally, it also has a low ESR and low self-inductance, making it ideal for various filtering applications.

Conclusion

The QXK2J154KTP is a polypropylene non-polar film capacitor that has a bipolar rated voltage of 630V, a capacitance range of 100 to 680nF and a tolerance range of ±0.5%. It is suitable for use in AC and DC applications, such as voltage dividers, filters, power shunts, and capacitive dropping resistors. Its working principle is based on the archetype of all film capacitors, whereby a thin dielectric film creates an electric field that stores electric charge, allowing it to act as a voltage control or an electrical filter.
