Film capacitors, also known as film dielectric capacitors, can be divided into metalized film capacitors, polyester film capacitors, polypropylene film capacitors and polystyrene film capacitors in the application field according to the raw materials used to make the dielectric. The metalized film capacitor generally consists of two layers of metallized aluminum-plastic film electrodes and metal-plastic film as insulation; polyester film capacitors are made of two layers of metallized polyester film as electrodes, and the insulating material between them is also polyester film; polypropylene film capacitors are made of two layers of metallized polypropylene film electrodes and polypropylene film as the insulating material; the polystyrene film capacitor has two layers of metallized polystyrene film electrodes and polystyrene film as the insulating material between them.

QXK2J684KTP is a new type of film capacitor, belonging to metalized film capacitors. Its main feature is its larger capacitance, which can be as large as 3.3uF, and its operating temperature range is -45°C to +125°C. Its working principle is the principle of electrical double layer, that is, when the electrical field is applied to the metal dielectric boundary (metal film), the electrons with negative charge direction migrate to the dielectric interface and form an electric double layer.

In order to ensure its capacitance and anti-interference ability, when the thickness of the metalized film of QXK2J684KTP is between 102μm and 117μm, and the K value of the electrode is between 20 and 60. The above mentioned parameters pave the way for the film capacitor to be widely used in the circuit with high stability, high reliability, and superior performance.

It can be widely applied to a variety of fields such as throttle circuit, AC/DC power and etc., due to its sturdier film and electrode structure. In addition, the film capacitor can achieve a low impedance and high reliability even if the temperature is as low as -45°C, or as high as +125°C, and no insulation and leakage will occur during its long-term work.

The structure of QXK2J684KTP is slightly different from ordinary film capacitors. It has single metalized layer, the temperature range is wider, and the capacitance value is higher. In order to ensure the accuracy of the capacitance value, it is necessary to limit the thickness of the film and the value of the K electrode. The metalized layer of the electrode should be of a high quality, so as to ensure its applications in the field of power and motor control.

Capacitors with higher capacitance and higher operating temperature are needed in more and more fields, so the design of QXK2J684KTP with its special structure and higher value of capacitance can greatly meet the needs of the modern application field. QXK2J684KTP is recognized as a reliable and good quality capacitor with superior performance and is widely applied in power, motor control and other fields.
