我们在购买任何产品的时候都会考虑到实用性，也就是说适合自己的才是最好的。同样在购买薄膜电容器的时候也要结合使用场景购买合适的薄膜电容。那么薄膜电容器购买时需要避免哪些常见的误区呢？让我们一起来了解一下。

　　When we buy any product, we will consider the practicability, that is to say, what suits us is the best. Similarly, when purchasing thin-film capacitors, we should also purchase appropriate thin-film capacitors in combination with the use scenarios. So what common mistakes should be avoided when purchasing thin film capacitors? Let's take a look at it.

　　有钱人买东西都是只卖最贵的，不买最好的。这也只是有钱人的消费观念，对于经营企业而言，成本是首要考虑的因素。

　　Rich people only sell the most expensive, not the best. This is only the consumption concept of the rich. For enterprises, cost is the primary factor to be considered.

　　所以在购买薄膜电容的时候，既要保证电容的优良性能、稳定性好等基本的特征之外，还要考虑到其他元器件的质量，还有就是整体的电路设计的连贯性，也就是说适合的才是最好的。

　　Therefore, when purchasing thin-film capacitors, we should not only ensure the excellent performance and stability of the capacitor, but also consider the quality of other components, as well as the coherence of the overall circuit design, that is to say, the best one is suitable.

　　其次就是薄膜电容器购买时容量大小的考量。

　　The second is the consideration of the capacity of the film capacitor when it is purchased.

　　很多的人认为电容量越大越好，选择薄膜电容器时，电容量是越大越好，但我们要知道，电容量越大，电容器的体积也越大，这样不仅会占用更多的空间，而且也会影响到散热，还会增加产品的成本。

　　Many people think that the larger the capacitance, the better. When choosing the film capacitor, the larger the capacitance is, the better. But we should know that the larger the capacitance is, the larger the capacitor volume is. This will not only occupy more space, but also affect the heat dissipation and increase the cost of the product.

　　所以说我们要根据薄膜电容的应用场景以及整体电路的需求选择适合的薄膜电容，切忌盲目追求价格高的和容量大的。

　　Therefore, we should choose the suitable film capacitor according to the application scenarios of the film capacitor and the demand of the whole circuit, and avoid blindly pursuing the high price and large capacity.
