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

3、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、itation,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、滤高频改波性能极好。钽电容知识介绍I
