Dear sir:
Our company have ever used your products last year.
I would like to know whether you have electro-capacitor which can work under -40 centi degree. Thanks!
兄弟,如果从数值上讲,附件中HZ系列的高频阻抗与ESR是相差无几的,几乎相等.但从定义上讲,那是两个概念,ESR是纯内阻(等效串联电阻Equivalent series resistance),而阻抗(Impedance)则是内阻、容抗、感抗的矢量和.
120HZ时阻抗远大于ESR,而接近谐振频率时(铝电解谐振频率10K~100K),阻抗与ESR几乎相等.
