2、 黄钽品牌主要是：AVX 、KEMET 黑钽主要品牌是：NEC、NICHICON 市场占有方面：AVX远高于KEMET，NEC高于 NICHICON。钽电容品牌介绍Internal | DEGO | 2009 | DEGO Micro Electronics 2009.

3、rights.AVX与KEMET的优劣： AVX在军用，民用市场上的占有量都很大，在普通电容的市场上，AVX无论品质还是市场占有量都远强与KEMET。价格上，AVX比KEMET更贵。KEMET主要问题是其电容的耐压值不够，举例说：100uf 10v的电容，测试的电压按道理应该能达到5V，但若真用5V电压去测试的话，很可能会击穿。 至于VISHAY，其钽电容大多用于军工，其普通钽电容市场占有量比较少。钽电容品牌介绍Internal | DEGO | 2009 | DEGO Micro Electronics 2009.

4、y disposal, exploitation,reproduction, editing, distribution, as well as in the event of applications for industrial property rights. 黑钽是开模将钽粉压成型，而黄钽，是在表面用聚氧树脂包裹而成。由于生产工艺的原因，黑钽的内部空间没有得最有效的利用，所以黄钽能做的容量会比黑钽要大，也就是说有些黄钽能做到的规格型号，黑钽做不了。 钽电容全称是钽电解电容，也属于电解电容的一种，使用金属钽做介质，不像普通电解电容那样使用电解液，钽电容的特点是寿命长、耐高温、准确度高、滤

5、高频改波性能极好。钽电容知识介绍Internal | DEGO | 2009 | DEGO Micro Electronics 2009.

6、的地方。在钽电容器工作过程中，具有自动修补或隔绝氧化膜中的疵点所在的性能，使氧化膜介质随时得到加固和恢复其应有的绝缘能力，而不致遭到连续的累积性破坏。这种独特自愈性能，保证了其长寿命和可靠性的优势。钽电容知识介绍Internal | DEGO | 2009 | DEGO Micro Electronics 2009.
