Film Capacitor

A film capacitor, generally known as a plastic film capacitor, is an electronic passive component used to store electrical energy in an electric field. It is constructed by stacking two parallel conductive plates on top of a dielectric plastic film, made of either polyester, polypropylene, teflon or polycarbonate. These two conductive plates act like two isolated electric plates, and collect or release electric charge depending on the relative voltage of the two plates. The most important feature of a film capacitor is its high dielectric constant, which allows it to be used in a wide range of applications, such as decoupling circuits, motor control, electromagnetic interference (EMI) filtering, high-frequency filtering, voltage transient suppression, and voltage regulation.

QXP2J683KRP7FP Application Field and Working Principle

The QXP2J683KRP7FP is an axial-type film capacitor that has a wide range of applications in various industries. It is primarily used in motor control and power supply filters applications due to its low parasitic inductance, which minimizes motor noise and voltage spikes. The QXP2J683KRP7FP also finds applications in decoupling, power filtering, surge protection, and frequency control, particularly for high-frequency applications.

The working principle of the QXP2J683KRP7FP is based on the electrostatic field between two oppositely charged metal plates. The two metal plates are separated by a non-conductive plastic film, which serves as the dielectric. When voltage is applied to the capacitor, an electric field is generated between the two metal plates. This electric field creates an electrical charge on the dielectric film, which creates an electrostatic capacitance between the two plates. This capacitance is the basis for the working principle of the QXP2J683KRP7FP.

The QXP2J683KRP7FP is also designed with a self-healing system to protect against voltage spikes and surges. The self-healing mechanism is based on the re-distribution of the charge between the two plates of the capacitor. This helps to protect it from voltage surges and makes it an ideal choice for high-frequency applications.

The QXP2J683KRP7FP provides efficient performance with its low equivalent series inductance (ESL) and excellent high-frequency performance. Its capacitance range varies from 0.1pF to 63pF and it has a maximum operating voltage of 250VDC. It is also RoHS compliant and holds excellent long-term stability.
