Film capacitors (or film dielectrics) are capacitors in which the dielectric material is a thin plastic film. Unlike electrolytic capacitors, which are made with a liquid moistening the oxide dielectric, film capacitors are the most reliable type for high voltage, high frequency and constant ripple current applications at temperatures from -55℃ up to 125℃.

The QXK2E683KTP7FG is a commercial-grade, polyester-film capacitor from Fock Electronics. The product features a case size of 7.3 x 5.8 mm², and a Capacitance tolerance of ±10%, +25/-50%. The voltage range is 250 VAC. Its working temperature ranges from -55℃ to +125℃.

The QXK2E683KTP7FG covers a wide array of possible applications. It is capable of being used in snubber loop applications, AC line-frequency bypassing, as well as for general-purpose AC power applications. Moreover, with its stable performance at high temperatures and high leakage current, it is suitable for use in high-power density applications.

Furthermore, the QXK2E683KTP7FG is designed for high-precision instruments that need precise capacitance performance such as audio frequency transformers, high-power inverter circuits, EMC filter circuits, etc.

The working principle of the QXK2E683KTP7FG is based on the same principle that is used in other capacitors; its ability to store electrical charges between two metal plates separated by a dielectric material. The electrical charges are held in equal and opposite form between the capacitor’s two conducting plates, which helps provide a stable current flow in AC circuits. Film capacitors are able to store a large amount of energy, and this energy can be released as a sudden or gradual burst of electrical current.

The QXK2E683KTP7FG presents a variety of features which makes it a great choice for AC power and high-precision instrument applications. Its polyester film dielectric provides excellent stability of capacitance and low temperature coefficients over a wide temperature range, while its robust dielectric film and a voltage range of up to 250 VAC make it suitable for mid to high-voltage applications. It can be used in many types of applications, from low-power home appliances and audio equipment, to high-power density applications such as snubber loop and EMC filter circuits.
