隨著電(dian)(dian)感行(xing)業的(de)發(fa)展，電(dian)(dian)感制造技(ji)術也越來越先進，一體成(cheng)型電(dian)(dian)感的(de)應(ying)用(yong)是非常廣泛(fan)的(de)。本(ben)篇要討論的(de)并(bing)不是一體成(cheng)型電(dian)(dian)感的(de)行(xing)業應(ying)用(yong)問(wen)題，而是關于一體成(cheng)型電(dian)(dian)感型號(hao)選擇(ze)的(de)問(wen)題。

一(yi)、一(yi)體成型電感產品設計(ji)時我們(men)需要(yao)進行考(kao)慮的兩個具有重要(yao)影響因素：

1、飽和電(dian)流(liu): 電(dian)感的(de)(de)變(bian)化(hua)，隨著通過電(dian)感的(de)(de)電(dian)流(liu)的(de)(de)增加，磁密度會(hui)增加，當磁飽和時，電(dian)感會(hui)迅速下降，電(dian)感的(de)(de)電(dian)流(liu)值下降30% 是標準(zhun)值。

2、溫升電(dian)(dian)流Irms:電(dian)(dian)氣(qi)設備在額定電(dian)(dian)壓和額定功率(lv)下運行時(shi)的電(dian)(dian)流。

二(er)、在設計集成電感時，溫(wen)升(sheng)電流和飽和電流是兩個需要考慮的重(zhong)要因素:

1、飽和電(dian)(dian)(dian)(dian)流Isat:隨著(zhu)電(dian)(dian)(dian)(dian)感的變(bian)化，磁(ci)場密度會隨著(zhu)通過電(dian)(dian)(dian)(dian)感的電(dian)(dian)(dian)(dian)流的增加而增加。當(dang)達到磁(ci)飽和時(shi)，電(dian)(dian)(dian)(dian)感的電(dian)(dian)(dian)(dian)感會迅(xun)速(su)下(xia)降，一般(ban)以(yi)電(dian)(dian)(dian)(dian)感下(xia)降30%時(shi)的電(dian)(dian)(dian)(dian)流值為標準(zhun)。飽和電(dian)(dian)(dian)(dian)感是一種磁(ci)滯回(hui)線(xian)矩形比高、初始磁(ci)導率高、矯頑(wan)力低(di)、磁(ci)飽和點(dian)明顯(xian)的電(dian)(dian)(dian)(dian)感，在電(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)路(lu)中常(chang)用作可控延時(shi)開(kai)關(guan)元件(jian)。

2、溫升電(dian)流(liu)Irms：用電(dian)安全設備在額(e)定(ding)電(dian)壓下,按照(zhao)系統額(e)定(ding)輸出(chu)功率進行運(yun)行時的電(dian)流(liu)。

除了(le)上述相關(guan)參數(shu)，集成(cheng)電(dian)(dian)感(gan)(gan)的(de)關(guan)鍵(jian)參數(shu)還(huan)有:DCR(直流(liu)電(dian)(dian)阻)、飽和(he)電(dian)(dian)流(liu)(Isat)、耐壓(ya)等。一體(ti)成(cheng)型電(dian)(dian)感(gan)(gan)的(de)溫升電(dian)(dian)流(liu)與飽和(he)電(dian)(dian)流(liu)簡(jian)單(dan)點就是從(cong)這兩個大(da)的(de)方面來(lai)看(kan)，如果你還(huan)不(bu)懂如何正確選擇一體(ti)成(cheng)型電(dian)(dian)感(gan)(gan)，歡迎留(liu)言咨詢我(wo)們！
