Film capacitors are capacitors that use a insulating film as a dielectric. They are used in a wide variety of applications, ranging from consumer electronics to industrial power quality and aerospace applications. The QXK2E154KTP is an example of a film capacitor that is commonly used in these types of applications.

The QXK2E154KTP is a type of metallized polypropylene film capacitor. It is a low-voltage capacitor designed for applications across a wide range of industries. It has excellent temperature stability, a relatively low dissipation factor, and high insulation resistance. It is well suited for use in power circuits and is highly reliable. It is also capable of carrying high surge current and has superior humidity tolerance.

The QXK2E154KTP is a surface-mount capacitor, so it is easy to install and comes in standard sizes. It can be used in many technically demanding applications, including switched-mode power supplies, DC-DC converters, voltage regulators, motor drives, and power transmission systems. It is also well-suited for automotive and telecommunication applications, with some variants also being suitable for lightning and surge protection. Due to its size, it is often used as an alternative to larger capacitors with a lower capacitance.

In terms of application field and working principle, the QXK2E154KTP capacitor consists of a metalized polypropylene film as the dielectric, with a metal-coated sacrificial layer underneath. The dielectric has a relatively low dielectric constant so that its capacitance remains relatively stable over frequency. The metal-coated sacrificial layer creates a low-resistance path to increase the device’s capacitance and its voltage capability. Also, metalized films also provide a high insulation resistance. The capacitor also has an aluminum case that serves to protect the components. The capacitor is then connected to the PCB by leads.

In terms of electrical characteristics, the QXK2E154KTP is a low-voltage capacitor with a maximum working voltage of 550 volts. It has a low dissipation factor of 0.2%, a Capacitance Tolerance of ± 5%, and a temperature coefficient of ±30ppm/°C. Its capacitance range is from 0.001uF to 5600uF. Its dimension ranges from 10mm to 45mm, and its size ranges from 5mm to 35mm.

The QXK2E154KTP is a film capacitor with excellent performance and reliability, making it an ideal choice for many applications. It is well-suited for use in power circuits, automotive applications, and DC-DC converters. It also has excellent temperature stability and high insulation resistance, making it suitable for a wide range of applications. By connecting it to a PCB via leads, it can be used as a long-term low-voltage capacitor, however it is also highly reliable and capable of carrying high surge current.
