薄膜电容的种类很多，以金属化聚丙烯薄膜电容为例，主流型号+定制型号，甚至有上千种类型，这也导致CBB电容选型的时候比较困难。其实CBB薄膜电容选型并不复杂，我们只需要重点考虑几个参数就足够了。

　　There are many kinds of film capacitors. Take metallized polypropylene film capacitors as an example, there are mainstream models + customized models, and even thousands of types. This also makes it difficult to select CBB capacitors. In fact, the modeling of CBB thin film capacitor is not complicated, we only need to focus on a few parameters.

　　其实想要找到正确的薄膜电容型号很简单，大家在咨询的时候只要知道这几种参数即可。

　　In fact, to find the right film capacitor model is very simple, we need to know these parameters when consulting.

　　1、容量。以CBB22电容为例，它的容量范围是：0.0047-3.3Uf。

　　Capacity. Taking CBB22 capacitor as an example, its capacity range is 0.0047-3.3uf.

　　2、误差。常见的误差范围有：±5％（J），±10％（K），±20％（M）。

　　Error. The common error ranges are ± 5% (J), ± 10% (k) and ± 20% (m).

　　3、尺寸。这个最多，而且还可以定制生产。

　　Size. This is the most, and it can be customized.

　　4、电压。主流电压主要有250V，400V，630V。
