鋁電解電容的特點是容量大，但是漏電大，穩定性差，有正負極性，適宜用于電源濾波或者低頻電路中。使用的時候，正負極不要接反。那么購買鋁電解電容注意哪幾個細節？

　　Aluminum electrolytic capacitor is characterized by large capacity, but large leakage, poor stability, positive and negative polarity, suitable for power filter or low-frequency circuit. When using, the positive and negative poles should not be reversed. So what are the details of buying aluminum electrolytic capacitor?

　　1、選擇正規有實力的廠家

　　1. Choose regular and powerful manufacturers

　　廠家一定要有一定的實力，有一定的技術和先進的設備才能生產出高品質的產品，必要時可以選擇到廠考察，自己真實看到的才可靠。

　　Manufacturers must have certain strength, have certain technology and advanced equipment to produce high-quality products, when necessary, they can choose to visit the factory, and what they really see is reliable.

　　2、產品的主要參數是否能達到要求

　　2. Can the main parameters of the product meet the requirements

　　先提供樣品測試，只有經過自己測試的數據才是真實的，特殊產品可能還需要定制，能提供特殊定制服務也是關鍵。

　　Provide sample testing first. Only the data that has been tested by yourself is true. Special products may need to be customized. It is also key to provide special customized services.

　　3、價格合適

　　3. The price is right

　　一分錢一分貨，好的產品一定會有它的價值，所以想要質量可靠的產品一定不能單純的圖便宜。

　　A penny for goods, a good product will have its value, so you want reliable products must not be simply cheap.

　　4、交期和服務

　　4. Delivery and service

　　交期的保障是很重要的，如果有了大訂單肯定需要快速的采購到原材料。在服務方面要有一定的技術支持，如果電容在應用方面出現問題是否能提供解決方案這些都是很重要的。更多電容相關資訊請點擊進入：http://www.dsbb.net.cn

　　The guarantee of delivery time is very important. If you have a large order, you must purchase raw materials quickly. In terms of service, there should be some technical support. If there are problems in the application of capacitors, it is very important to provide solutions.
