薄膜电容器纹波电流更高？

　　Higher ripple current of thin film capacitor?

　　这是一个参照物的问题，薄膜电容器如果和普通的铝电解电容器相比确实是这样，但是，实际上在工业领域和新能源领域，一般有经验的工程师会选用较大纹波电流的支链型有机酸体系的工业电容器。

　　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.

　　薄膜电容器的标准是60度的温度下的纹波电流，我们以常用的4700uf铝电解举例，如果是工业用的电解电容器，纹波电流标准一般在15.4左右，如果在70度下，选用有机酸体系产品，纹波电流会乘以2.3倍，同时在乘以1.35倍的修正系数，基本在48A左右，不是通常所说的15A,所以和薄膜电容器基本在相近的水平线上。

　　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.

　　电解电容器的寿命短？

　　Short life of electrolytic capacitor?

　　同样是用了普通的85度2000小时的标准的铝电解电容器做比较，但实际上在工业领域尤其是在新能源领域，有经验的工程师一般会选用105度5000小时的工业极电解电容器产品，如果实际实用环境温度在45度，则使用寿命在40年，如果使用温度在55度，则使用寿命在20年，即使使用温度到65度也可使用10年，完全可以满足客户寿命要求。

　　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.

　　薄膜电容是温升较低？

　　Is the temperature rise of thin film capacitance low?

　　薄膜电容是温升较低，电解温升较高，但两者对温升的要求是不同的，就向前面所说的，薄膜温升12度就有大问题了，电解温升30－40度，都可以政常工作，所以说，这二者是完全没有可比性的。

　　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.

　　在工业领域，不论是从性价比，可靠性和安全性，工业有机酸体系的铝电解电容器是远远优于薄膜电容器的，但在高频和交流领域，薄膜电容器将发挥他的作用。

　　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.
