Introduction

Film capacitors are capacitors that use plastic films as the dielectric. They are designed to be compact, lightweight and very efficient in electrical circuits. They are popularly used in signal processing applications and in other high-frequency applications. One of the most well-known types of film capacitors is the MKP386M518125JT8. This article will discuss the application field and working principle of the MKP386M518125JT8.

Application Field of the MKP386M518125JT8

The MKP386M518125JT8 is an aluminium electrolytic capacitor with a polypropylene dielectric film. It is mainly designed for applications requiring low-impedance, high-frequency and low-voltage operation. Its main applications are:

• Filter circuits:
  • Adaptive filters
  • Audio paths
  • Decoupling
  • Frequency-dependent compensation products
• Power supplies:
  • DC-DC converters
  • Uninterruptible power supplies
  • Switch-mode power supplies
• Signal processing:
  • Surveillance and other wireless systems
  • Data acquisition and analysis

Working Principle of the MKP386M518125JT8

The MKP386M518125JT8 is an aluminium electrolytic capacitor with a polypropylene dielectric film. The polypropylene film acts as a dielectric because it has the ability to store a charge and allow for current to flow freely between its plates. When a voltage difference is applied to the device, the electric field created between the plates causes a redistribution of the electric charges, forming a capacitance. This capacitance is then used to store a charge or dissipate heat. When a voltage is applied to the MKP386M518125JT8, the charge stored in the capacitance will increase and when the voltage is removed, the capacitance will discharge. This creates a voltage to current conversion, which is used as a signal conditioning device in many applications. The capacitor’s stability and accuracy are superior to that of traditional electrolytic capacitors because the polypropylene film does not degrade over time. The MKP386M518125JT8 also has a wide temperature range (up to 125°C) and is RoHS compliant, making it suitable for use in commercial applications.
