Film capacitors, also known as plastic film capacitors, are one of the most widely used types of capacitors in electronic circuit design and production.They are lightweight, have high stability, high insulation, low reactance and excellent reliability and safety. The MEXY2A105K is a film capacitor with a robust design and high performance in various applications.

Structure of MEXY2A105K

The main components of MEXY2A105K capacitors are the metallized film, an insulating film and an external housing. The metallized film is composed of a polyester film with a thin, conductive metal layer applied to the surface. The core of the capacitor is the insulating film, which is composed of various materials such as polypropylene, polycarbonate and polyester. The external housing is made of a polyester/polypropylene dielectric material which acts as an extra barrier between the internal parts of the capacitor and the outside environment.

They are suitable for the power supply or filter at high voltage power supply systems, PFC (Power Factor Correction), EMI (Electromagnetic Interference), high frequency rectifier filter, snubber circuits and across the line applications. In addition, they are widely used in motor drives, inverters, UPS, Induction heating, welding and frequency conversions.

MEXY2A105K Working Principle

MEXY2A105K capacitors rely on the principle of electrostatic coupling between two conductive plates to store energy. The capacitor consists of two plates, one of which is a metallized film and the other is an insulating film. When a voltage is applied to the plates, an electrical current is generated between them, creating a net potential difference between them. This potential difference is what allows the capacitor to store a charge.

The electrical current generated between the two plates is known as capacitance. The capacitance of a MEXY2A105K capacitor is determined by the ratio of the surface area and plate separation. Increasing either the surface area or the plate separation increases the capacitance. The capacitor\'s capacitance is expressed in terms of Farads (F), and is designated by the letter C. The unit of capacitance, Farad, is equivalent to one Coulomb per Volt.

The charge stored in the capacitor can remain there for a certain period of time. This time is known as the time constant and is usually represented by the letter T. A longer time constant results in the capacitor being able to store more energy, and vice versa. When the capacitor is charged with a certain amount of energy, the energy is released when the capacitor is discharged. In this way, the capacitor works as a kind of "energybank" for the connected circuit.

The MEXY2A105K has proven to be an excellent capacitor for a range of applications. It has a robust design, high performance and excellent reliability. This has made it one of the most widely used film capacitors available.
