我們在購買任何產品的時候都會考慮到實用性，也就是說適合自己的才是最好的。同樣在購買薄膜電容器的時候也要結合使用場景購買合適的薄膜電容。那么薄膜電容器購買時需要避免哪些常見的誤區呢？讓我們一起來了解一下。

　　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.

　　有錢人買東西都是只賣最貴的，不買最好的。這也只是有錢人的消費觀念，對于經營企業而言，成本是首要考慮的因素。

　　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.

　　所以在購買薄膜電容的時候，既要保證電容的優良性能、穩定性好等基本的特征之外，還要考慮到其他元器件的質量，還有就是整體的電路設計的連貫性，也就是說適合的才是最好的。

　　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.

　　其次就是薄膜電容器購買時容量大小的考量。

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

　　很多的人認為電容量越大越好，選擇薄膜電容器時，電容量是越大越好，但我們要知道，電容量越大，電容器的體積也越大，這樣不僅會占用更多的空間，而且也會影響到散熱，還會增加產品的成本。

　　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.

　　所以說我們要根據薄膜電容的應用場景以及整體電路的需求選擇適合的薄膜電容，切忌盲目追求價格高的和容量大的。

　　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.
