之前我們說過了貼片屏蔽電感和普通貼片電感的差(cha)別，那么今天來跟(gen)大家說一說貼片屏蔽電感有什(shen)么樣的作用，應該用在哪些地方呢？

屏蔽電感因為其具有耐大電流，高儲能，低直流電阻等物理特性，常用于顯示器的DC/DC轉換器；LED照明；汽車產品上面。
屏蔽電感在電路中起到屏蔽作用的同時，還起到耦合的作用。屏蔽貼片電感為降低交變電場對敏感電路的耦合干擾電壓，電感可以(yi)在干擾(rao)(rao)源和(he)敏(min)感(gan)電(dian)(dian)(dian)(dian)路(lu)之間設(she)置導電(dian)(dian)(dian)(dian)性好的(de)(de)金(jin)(jin)(jin)屬(shu)(shu)屏(ping)(ping)(ping)蔽(bi)(bi)體，并(bing)將金(jin)(jin)(jin)屬(shu)(shu)屏(ping)(ping)(ping)蔽(bi)(bi)體接(jie)地。交(jiao)變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)場(chang)對敏(min)感(gan)電(dian)(dian)(dian)(dian)路(lu)的(de)(de)耦合干擾(rao)(rao)電(dian)(dian)(dian)(dian)壓大(da)小(xiao)取(qu)決于交(jiao)變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)場(chang)電(dian)(dian)(dian)(dian)壓、耦合電(dian)(dian)(dian)(dian)容和(he)金(jin)(jin)(jin)屬(shu)(shu)屏(ping)(ping)(ping)蔽(bi)(bi)體接(jie)地電(dian)(dian)(dian)(dian)阻之積。只要(yao)設(she)法使金(jin)(jin)(jin)屬(shu)(shu)屏(ping)(ping)(ping)蔽(bi)(bi)體良好接(jie)地，就能使交(jiao)變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)場(chang)對敏(min)感(gan)電(dian)(dian)(dian)(dian)路(lu)的(de)(de)耦合干擾(rao)(rao)電(dian)(dian)(dian)(dian)壓變(bian)(bian)(bian)得很小(xiao)。電(dian)(dian)(dian)(dian)場(chang)屏(ping)(ping)(ping)蔽(bi)(bi)以(yi)反射為(wei)(wei)主，因此屏(ping)(ping)(ping)蔽(bi)(bi)體的(de)(de)厚度不(bu)必過(guo)大(da)，而以(yi)結(jie)構強度為(wei)(wei)主要(yao)考慮因素(su)。
