薄膜電容器紋波電流更高？

　　Higher ripple current of thin film capacitor?

　　這是一個(gè)參照物的問(wèn)題，薄膜電容器如果和普通的鋁電解電容器相比確實(shí)是這樣，但是，實(shí)際上在工業(yè)領(lǐng)域和新能源領(lǐng)域，一般有經(jīng)驗(yàn)的工程師會(huì)選用較大紋波電流的支鏈型有機(jī)酸體系的工業(yè)電容器。

　　This is a problem of reference. If the film capacitor is compared with the ordinary aluminum electrolytic capacitor, it is true. However, in the industrial field and new energy field, generally experienced engineers will choose the industrial electric container with branch chain organic acid system with larger ripple current.

　　薄膜電容器的標(biāo)準(zhǔn)是60度的溫度下的紋波電流，我們以常用的4700uf鋁電解舉例，如果是工業(yè)用的電解電容器，紋波電流標(biāo)準(zhǔn)一般在15.4左右，如果在70度下，選用有機(jī)酸體系產(chǎn)品，紋波電流會(huì)乘以2.3倍，同時(shí)在乘以1.35倍的修正系數(shù)，基本在48A左右，不是通常所說(shuō)的15A,所以和薄膜電容器基本在相近的水平線上。

　　The standard of thin film capacitor is ripple current at 60 ℃. We take the common 4700uf aluminum electrolysis as an example. For industrial electrolytic capacitor, the ripple current standard is generally about 15.4. If the organic acid system product is selected at 70 ℃, the ripple current will be multiplied by 2.3 times, and the correction coefficient multiplied by 1.35 times is basically about 48A, not 15A, So it is basically on the same horizontal line as the film capacitor.

　　電解電容器的壽命短？

　　Short life of electrolytic capacitor?

　　同樣是用了普通的85度2000小時(shí)的標(biāo)準(zhǔn)的鋁電解電容器做比較，但實(shí)際上在工業(yè)領(lǐng)域尤其是在新能源領(lǐng)域，有經(jīng)驗(yàn)的工程師一般會(huì)選用105度5000小時(shí)的工業(yè)極電解電容器產(chǎn)品，如果實(shí)際實(shí)用環(huán)境溫度在45度，則使用壽命在40年，如果使用溫度在55度，則使用壽命在20年，即使使用溫度到65度也可使用10年，完全可以滿足客戶壽命要求。

　　The standard aluminum electrolytic capacitor with 85 ℃ and 2000 hours is also used for comparison, but in fact, in the industrial field, especially in the field of new energy, experienced engineers generally choose the industrial electrode electrolytic capacitor products with 105 ℃ and 5000 hours. If the actual practical environment temperature is 45 ℃, the service life is 40 years; if the service temperature is 55 ℃, the service life is 20 years, Even if the service temperature is up to 65 ℃, it can be used for 10 years, which can fully meet the life requirements of customers.

　　薄膜電容是溫升較低？

　　Is the temperature rise of thin film capacitance low?

　　薄膜電容是溫升較低，電解溫升較高，但兩者對(duì)溫升的要求是不同的，就向前面所說(shuō)的，薄膜溫升12度就有大問(wèn)題了，電解溫升30－40度，都可以政常工作，所以說(shuō)，這二者是完全沒(méi)有可比性的。

　　The temperature rise of thin film capacitor is lower than that of electrolysis, but the requirements for temperature rise are different. As mentioned above, the temperature rise of 12 ℃ for thin film is a big problem. The electrolytic temperature rise of 30-40 ℃ can work normally. Therefore, there is no comparability between the two.

　　在工業(yè)領(lǐng)域，不論是從性價(jià)比，可靠性和安全性，工業(yè)有機(jī)酸體系的鋁電解電容器是遠(yuǎn)遠(yuǎn)優(yōu)于薄膜電容器的，但在高頻和交流領(lǐng)域，薄膜電容器將發(fā)揮他的作用。

　　In the industrial field, aluminum electrolytic capacitors based on industrial organic acid system are far better than thin film capacitors in terms of cost performance, reliability and safety. However, thin film capacitors will play an important role in high frequency and AC fields.
