采購薄膜電容就要根據應用環境來選擇適合型號的電容元器件。今天我們就一起來了解下聚酯薄膜電容的用途及優勢有哪些？
The purchase of thin film capacitors depends on the application environment to choose the appropriate type of capacitor components. Today, we will learn about the use and advantages of polyester film capacitors?
聚酯薄膜電容器屬有機薄膜電容器類，又稱滌綸電容器。它是以金屬箔或金屬膜為電極，以聚對苯二甲酸乙二醇酯(簡稱聚酯)薄膜為介質，卷繞成形并裝入塑料殼密封而成的。有的電容器是將卷好成形的芯子用帶色的環氧樹脂包封。用金屬膜式電極制作的電容器稱為金屬化聚酯薄膜電容器。
Polyester film capacitor belongs to organic film capacitor class, also known as polyester capacitor. It is made of metal foil or metal film as electrode and polyethylene terephthalate (PET) film as medium by winding and sealing in plastic shell. In some capacitors, the core is wrapped with colored epoxy resin. The capacitor made of metal film electrode is called metallized polyester film capacitor.
聚酯薄膜電容具有優良的力學性能、電性能和光學性能，因此應用范圍非常廣泛，例如，相片底片、磁帶、錄像帶、縮微膠片、包裝膜和電容器等。
Polyester film capacitors have excellent mechanical, electrical and optical properties, so they have a wide range of applications, such as photographic film, magnetic tape, video tape, microfilm, packaging film and capacitor, etc.
聚酯薄膜電容采用金屬化聚酯膜，無感卷繞結構，并且容量范圍寬，體積小，重量輕。因此安裝的時候也是比較便捷的，不僅如此，聚酯薄膜電容的自愈性好，使用壽命較長。同時，聚酯薄膜電容還采用了阻燃性環氧粉末包封。
Polyester film capacitor adopts metallized polyester film, non inductive winding structure, and has wide capacity range, small volume and light weight. Therefore, the installation is more convenient, not only that, polyester film capacitor self-healing good, long service life. At the same time, the polyester film capacitor is also encapsulated with flame retardant epoxy powder.
從專業的角度來說，聚酯薄膜電容由于穩定性較高，因此對于一些嚴格要求穩定性的場合來說，是最為適合的選擇。比如在電子儀器或者是儀表以及收音機上，其能夠作為耦合或者是旁路來使用。
From a professional point of view, polyester film capacitor is the most suitable choice for some occasions where stability is strictly required due to its high stability. For example, in electronic instruments or meters and radios, it can be used as a coupling or bypass.
對于聚酯薄膜電容器來說，不僅具有以上的優勢，而且還有較強的耐熱性以及耐濕性，還具有一定的耐壓性。
For polyester film capacitor, not only has the above advantages, but also has strong heat resistance and moisture resistance, but also has a certain degree of voltage resistance.
