薄膜電容器有多種不同種類及型號(hào)，根據(jù)使用場景的區(qū)別選擇適合型號(hào)的電容。今天我們主要來了解下有機(jī)薄膜電容器。有機(jī)薄膜電容有哪些優(yōu)點(diǎn)內(nèi)容？

　　There are many different types and models of thin-film capacitors. The suitable type of capacitors can be selected according to the different use scenarios. Today we are going to talk about organic film capacitors. What are the advantages of organic film capacitors?

　　1.體積縮小可取代以往使用電解電容的場合，并且具有更高的耐電壓能力；

　　The volume reduction can replace the previous occasions where electrolytic capacitors are used, and has higher voltage resistance;

　　2.不存在電解液泄露風(fēng)險(xiǎn)，具有更高的可靠性；

　　There is no risk of electrolyte leakage, so it has higher reliability;

　　3.在電路中遇到瞬時(shí)過壓時(shí)，具有自愈特性，能夠很好地保護(hù)電路安全，消除電路過壓擊穿短路風(fēng)險(xiǎn)；

　　When the circuit encounters instantaneous overvoltage, it has self-healing characteristics, which can well protect the circuit safety and eliminate the risk of circuit over-voltage breakdown and short-circuit;

　　4.采用無感卷繞技術(shù)，產(chǎn)品符合低電感特性，更能適應(yīng)電源系統(tǒng)不斷提升的工作頻率；

　　Adopting non inductive winding technology, the product meets the low inductance characteristics, and is more suitable for the rising working frequency of the power supply system;

　　5.采用低損耗介質(zhì)材料，產(chǎn)品具有低損耗特性，能夠承受更大紋波電流，發(fā)熱量較低；

　　Using low loss dielectric material, the product has low loss characteristics, can withstand larger ripple current, and has lower heating capacity;

　　6.無極性介質(zhì)材料，能夠承受反峰電壓，可滿足交、直流濾波電路使用等。

　　Nonpolar dielectric material, able to withstand reverse peak voltage, can meet the use of AC and DC filter circuit.

　　金屬化有機(jī)薄膜電容器的自愈有兩種不同的機(jī)理：一種是放電自愈；另一種是電化學(xué)自愈。前者發(fā)生在電壓較高下，所以也簡稱為高壓自愈；因?yàn)楹笳咴陔妷汉艿偷那闆r下也出現(xiàn)，所以常簡稱為低壓自愈。

　　The self-healing mechanism of metallized organic film capacitor has two different mechanisms: one is discharge self-healing; the other is electrochemical self-healing. The former occurs at a higher voltage, so it is also referred to as high voltage self-healing; because the latter also occurs in the case of very low voltage, it is often referred to as low-voltage self-healing.

　　金屬化有機(jī)薄膜電容器的最大特點(diǎn)是具有自愈能力，因此自愈所帶來的好處是主要的，但是，它也有不利之處，其中最大的害處就是自愈時(shí)造成電流脈沖，給電路帶來信號(hào)干擾，降低電路的重要性能——信噪比。所以對(duì)于一些要求特別高的電路，如高保真音響電路、高精度通信電路等，不能讓有機(jī)薄膜電容器在工作時(shí)發(fā)生自愈。

　　The biggest characteristic of metallized organic thin film capacitor is its self-healing ability, so the advantages brought by self-healing are main. However, it also has disadvantages. The biggest harm is the current pulse caused by self-healing, which brings signal interference to the circuit and reduces the important performance of the circuit signal-to-noise ratio. Therefore, for some circuits with high requirements, such as high fidelity audio circuit, high-precision communication circuit, the organic film capacitor can not be self-healing when working.

　　自愈的另一害處，是使用電容器的容量逐漸減少。若電容量在工作時(shí)，自愈次數(shù)很多，就會(huì)導(dǎo)致其容量和絕緣電阻顯著變小、損耗角大幅度上升，使電容器很快失效。

　　Another disadvantage of self-healing is that the capacity of capacitors is gradually reduced. If there are many self-healing times when the electric capacity is working, its capacity and insulation resistance will be significantly reduced, and the loss angle will be greatly increased, which will make the capacitor fail quickly.

　　總而言之，有機(jī)薄膜電容的應(yīng)用還是利大于弊，企業(yè)在購買有機(jī)薄膜電容器的時(shí)候要根據(jù)電容器的使用環(huán)境、電路特征等綜合因素選擇適合的電容元器件。更多相關(guān)電容元器件型號(hào)及種類請(qǐng)移步至產(chǎn)品中心：http://www.wnad.cn/cn/product/。

　　In a word, the advantages and disadvantages of the application of organic thin film capacitors are greater than the disadvantages. When purchasing organic thin film capacitors, enterprises should choose the appropriate capacitor components according to the comprehensive factors such as the operating environment and circuit characteristics of the capacitors.
