額定電壓 voltage rating對(duì)于額定功率之直流或交流(rms)電壓?？捎靡韵鹿接?jì)算，如果計(jì)算的值超過產(chǎn)品規(guī)格表內(nèi)的最高額定電
壓時(shí)，則以最高額定電壓為其額定電壓。
voltage rating can be calculated by formula as below, and the result calculated higher than the max voltage rating listed in table, the max voltage rating is the certain voltage rating of this value resistor. 公式如下 formula：
e=額定電壓 voltage rating (v)
e=√p×r
p=額定功率 power rating (w) r=阻值 resistance value (ω)
