ZX37-0.2電阻器適用于交流50赫茲
在高增益放大電路中.應(yīng)選用噪聲電動(dòng)勢(shì)小的電阻器,如金屬膜也阻器、碳膜電阻器和線繞電阻器。
?? 2.針對(duì)電路的工作頻率選用不同類堪的電阻器。線繞電阻器的分布參數(shù)較大,即使采用無感繞制的線繞電阻器,其分布參數(shù)也比非線繞電阻器大得多,因而線繞電阻不適合在高頻電路中工作。在低于50kHz 的電路中,由于電阻器的分布參數(shù)對(duì)電路工作影響不大,可選用線繞電阻器。
3.在高頻電路中的電阻器,要求其分布參數(shù)越小越好。所以,在高達(dá)數(shù)百兆赫的高頻電路中應(yīng)選用碳膜電阻器、金屬膜電阻器和金屬氧化膜電阻器。在超高頻電路中,應(yīng)選用超高頻碳膜電阻器。
