采购薄膜电容就要根据应用环境来选择适合型号的电容元器件。今天我们就一起来了解下聚酯薄膜电容的用途及优势有哪些？

　　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?

　　聚酯薄膜电容器属有机薄膜电容器类，又称涤纶电容器。它是以金属箔或金属膜为电极，以聚对苯二甲酸乙二醇酯(简称聚酯)薄膜为介质，卷绕成形并装入塑料壳密封而成的。有的电容器是将卷好成形的芯子用带色的环氧树脂包封。用金属膜式电极制作的电容器称为金属化聚酯薄膜电容器。

　　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.

　　聚酯薄膜电容具有优良的力学性能、电性能和光学性能，因此应用范围非常广泛，例如，相片底片、磁带、录像带、缩微胶片、包装膜和电容器等。

　　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.

　　聚酯薄膜电容采用金属化聚酯膜，无感卷绕结构，并且容量范围宽，体积小，重量轻。因此安装的时候也是比较便捷的，不仅如此，聚酯薄膜电容的自愈性好，使用寿命较长。同时，聚酯薄膜电容还采用了阻燃性环氧粉末包封。

　　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.

　　从专业的角度来说，聚酯薄膜电容由于稳定性较高，因此对于一些严格要求稳定性的场合来说，是最为适合的选择。比如在电子仪器或者是仪表以及收音机上，其能够作为耦合或者是旁路来使用。

　　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.

　　对于聚酯薄膜电容器来说，不仅具有以上的优势，而且还有较强的耐热性以及耐湿性，还具有一定的耐压性。

　　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.
