• Introduction

Film capacitors are a class of capacitors that use a thin dielectric film to store electrical energy. The most commonly used materials for these capacitors are polyethylene terephthalate (PET), polycarbonate (PC), polypropylene (PP), and Invar (FeNi alloy). They are widely used in many electronic and electrical systems and are noted for their high reliability, long life, and low ESR (equivalent series resistance). The QXP2G105KRP7FX Film capacitor is one such device that has a wide variety of applications and is noted for its excellent performance.

• Features

The QXP2G105KRP7FX is a non-polar aluminum electrolytic film capacitor with a snap-in mounting style. It has a small form factor, with its compact size making it suitable for applications where space is a primary constraint. The capacitor has a rated voltage of 2,000 VRMS and a rated capacitance of 1uF, making it suitable for high frequency applications. Its rated leakage current is a low 0.4mA, and its temperature range is -55 to +125°C. The device is available in three dielectric types: PET, PC, and PP.

• Application Field and Working Principle

The QXP2G105KRP7FX Film capacitor is widely used in a variety of applications, particularly those that require high frequency performance and good high temperature stability. Its small size makes it suitable for applications where space is at a premium, such as laptop computers, or any other portable electronic device. The capacitor is also well-suited for use in motor drives, power supplies, and other switching power supplies. The working principle of the QXP2G105KRP7FX Film capacitor is similar to that of a traditional electrolytic capacitor. The device consists of a thin insulating film (PET, PC, PP, or Invar, as noted above) which is sandwiched between two conducting plates (typically aluminum or tantalum). Electrical energy is stored in the form of an electric field across the two plates. When a voltage is applied to the plates, a current flows as electrons flow from one plate to the other, resulting in a charge and thus electrical energy being stored in the capacitor. The capacitance of the device varies with the thickness of the dielectric film and the size of the plates, and hence changes with the applied voltage.

• Advantages

The QXP2G105KRP7FX Film capacitor has a number of advantages over traditional electrolytic capacitors. Firstly, it has a much higher ESR than other types of capacitors. This means that it can handle higher peak currents more efficiently, making it ideal for applications such as motor drives and power supplies. Secondly, since the capacitor is a non-polar device, it does not require polarization and can be connected in either direction, making it less vulnerable to reverse voltage polarity. Additionally, film capacitors are very reliable and long-lasting; they are said to have a lifetime that is more than ten times that of traditional electrolytic capacitors.

• Conclusion

In conclusion, the QXP2G105KRP7FX Film capacitor is an excellent choice for a wide variety of applications due to its small size, high reliability, good high frequency performance, and low ESR. It is particularly well-suited to applications where space is a primary concern, such as laptop computers and portable electronic devices, as well as motor drives and power supplies. Thanks to its low leakage current and high temperature stability, it is also well-suited for use in more demanding environments.
