它與電感量L和交流電頻率f的關(guān)系為XL=2πfL品質(zhì)因素品質(zhì)因素Q是表示線圈質(zhì)量的一個(gè)物理量，Q為感抗XL與其等效的電阻的比值，即：Q=XL/R。它是指電感器在某一頻率的交流電壓下工作時(shí)，所呈現(xiàn)的感抗與其等效損耗電阻之比。電感器的Q值越高，其損耗越小，效率越高。線圈的Q值與導(dǎo)線的直流電阻，骨架的介質(zhì)損耗，屏蔽罩或鐵芯引起的損耗，高頻趨膚效應(yīng)的影響等因素有關(guān)。線圈的Q值通常為幾十到幾百。電感器品質(zhì)因數(shù)的高低與線圈導(dǎo)線的直流電阻、線圈骨架的介質(zhì)損耗及鐵心、屏蔽罩等引起的損耗等有關(guān)。分布電容任何電感線圈，其匝與匝之間、層與層之間，線圈與參考地之間，線圈與磁屏蔽罩間等都存在一定的電容，這些電容稱為電感線圈的分布電容。若將這些分布電容綜合在一起，就成為一個(gè)與電感線圈并聯(lián)的等效電容C。分布電容的存在使線圈的Q值減小，穩(wěn)定性變差，因而線圈的分布電容越小越好。額定電流額定電流是指電感器有正常工作時(shí)反允許通過(guò)的大電流值。若工作電流超過(guò)額定電流，則電感器就會(huì)因發(fā)熱而使性能參數(shù)發(fā)生改變，甚至還會(huì)因過(guò)流而燒毀。允許偏差允許偏差是指電感器上標(biāo)稱的電感量與實(shí)際電感的允許誤差值。一般用于振蕩或?yàn)V波等電路中的電感器要求精度較高。</p><p>
