磁(ci)環(huan) 又稱之為(wei)鐵(tie)氧體磁(ci)環(huan),是(shi)手機(ji)電源(yuan)(yuan)電路中(zhong)經常(chang)的(de)(de)使(shi)(shi)用的(de)(de)抗(kang)侵擾組(zu)件(jian)抗(kang)侵擾磁(ci)環(huan) ,對於高頻(pin)噪聲源(yuan)(yuan)有(you)挺好的(de)(de)壓設計(ji)制功能,普通的(de)(de)使(shi)(shi)用鐵(tie)氧體文件(jian)(Mn-Zn)制作成(cheng)。
磁環在(zai)各不相同的(de)速率下有各不相同的(de)輸(shu)出(chu)阻抗(kang)匹配(pei)(pei)匹配(pei)(pei)特(te)征參數,一樣 在(zai)底(di)頻時輸(shu)出(chu)阻抗(kang)匹配(pei)(pei)匹配(pei)(pei)有大有小,當網絡(luo)信號速率上(shang)升(sheng)磁環突出(chu)表現的(de)輸(shu)出(chu)阻抗(kang)匹配(pei)(pei)匹配(pei)(pei)快(kuai)速上(shang)升(sheng)。
各位都(dou)明白,電(dian)(dian)(dian)磁(ci)(ci)波(bo)(bo)(bo)(bo)波(bo)(bo)(bo)(bo)概(gai)率越高,越輕易(yi)輻射(she)能(neng)(neng)出(chu)(chu)去(qu)玩(要買高質的手提電(dian)(dian)(dian)腦主機箱也是要有效的減(jian)小電(dian)(dian)(dian)磁(ci)(ci)波(bo)(bo)(bo)(bo)流出(chu)(chu)),而(er)通常情況的電(dian)(dian)(dian)磁(ci)(ci)波(bo)(bo)(bo)(bo)波(bo)(bo)(bo)(bo)線(xian)(xian)都(dou)有不能(neng)(neng)手機屏蔽層(ceng)的,特別(bie)(bie)某(mou)些電(dian)(dian)(dian)磁(ci)(ci)波(bo)(bo)(bo)(bo)波(bo)(bo)(bo)(bo)線(xian)(xian)就變為很 好(hao)(hao)的外置天(tian)線(xian)(xian),閱讀有自(zi)然環境(jing)中(zhong)幾種繁(fan)雜的中(zhong)頻電(dian)(dian)(dian)磁(ci)(ci)波(bo)(bo)(bo)(bo)波(bo)(bo)(bo)(bo),而(er)某(mou)些電(dian)(dian)(dian)磁(ci)(ci)波(bo)(bo)(bo)(bo)波(bo)(bo)(bo)(bo)合成在(zai)本身(shen)互傳的電(dian)(dian)(dian)磁(ci)(ci)波(bo)(bo)(bo)(bo)波(bo)(bo)(bo)(bo)上,還會變換可是互傳的好(hao)(hao)用(yong)(yong)電(dian)(dian)(dian)磁(ci)(ci)波(bo)(bo)(bo)(bo)波(bo)(bo)(bo)(bo)。特別(bie)(bie)在(zai)磁(ci)(ci)環用(yong)(yong)下,使(shi)一(yi)般好(hao)(hao)用(yong)(yong)的電(dian)(dian)(dian)磁(ci)(ci)波(bo)(bo)(bo)(bo)波(bo)(bo)(bo)(bo)特別(bie)(bie)好(hao)(hao)的在(zai),又能(neng)(neng)特別(bie)(bie)好(hao)(hao)的阻止中(zhong)頻騷(sao)擾電(dian)(dian)(dian)磁(ci)(ci)波(bo)(bo)(bo)(bo)波(bo)(bo)(bo)(bo)的在(zai),然而(er)資金價廉。
這些(xie)朋友們在表明(ming)器訊(xun)號線,USB接觸線,恐怕高擋游(you)戲鍵盤(pan)、鼠標鍵盤(pan)上看的pp塑料小疙瘩型(xing)的二(er)合一式磁(ci)環(huan)就過(guo)高為(wei)奇了。
磁環的匝數使用
將整束電(dian)(dian)攬(lan)(lan)穿入一些(xie)鐵(tie)氧體磁(ci)環(huan)(huan)就分為了(le)一些(xie)共(gong)(gong)(gong)(gong)模(mo)扼(e)流(liu)圈(quan),選(xuan)擇必須要 ,也還(huan)能(neng)(neng)夠將電(dian)(dian)攬(lan)(lan)在磁(ci)環(huan)(huan)底下繞幾(ji)匝(za)(za)。匝(za)(za)數(shu)(shu)越(yue)多越(yue),對(dui)(dui)速度(du)較低(di)的(de)(de)干(gan)(gan)預控(kong)制(zhi)(zhi)合(he)理結(jie)果更好,而對(dui)(dui)速度(du)較高(gao)的(de)(de)燥音(yin)(yin)污染控(kong)創能(neng)(neng)力(li)不強。在合(he)理市(shi)政工程中,要選(xuan)擇干(gan)(gan)預直流(liu)電(dian)(dian)的(de)(de)速度(du)特(te)色來懂得調(diao)整磁(ci)環(huan)(huan)的(de)(de)匝(za)(za)數(shu)(shu)。常當(dang)干(gan)(gan)預網(wang)絡(luo)(luo)數(shu)(shu)據(ju)的(de)(de)頻帶寬(kuan)度(du)較寬(kuan)時,可在電(dian)(dian)攬(lan)(lan)上(shang)(shang)套的(de)(de)兩個(ge)磁(ci)環(huan)(huan),各(ge)個(ge)磁(ci)環(huan)(huan)繞聲(sheng)其(qi)他的(de)(de)匝(za)(za)數(shu)(shu),其(qi)實(shi)還(huan)能(neng)(neng)夠一起控(kong)制(zhi)(zhi)中頻干(gan)(gan)預和(he)超低(di)頻高(gao)壓發(fa)生器(qi)干(gan)(gan)預。從共(gong)(gong)(gong)(gong)模(mo)扼(e)流(liu)圈(quan)能(neng)(neng)力(li)的(de)(de)機制(zhi)(zhi)上(shang)(shang)看,其(qi)電(dian)(dian)位差越(yue)大(da),對(dui)(dui)干(gan)(gan)預控(kong)制(zhi)(zhi)合(he)理結(jie)果越(yue)很大(da)。而共(gong)(gong)(gong)(gong)模(mo)扼(e)流(liu)圈(quan)的(de)(de)電(dian)(dian)位差出(chu)自于(yu)共(gong)(gong)(gong)(gong)模(mo)電(dian)(dian)感(gan)(gan)(gan)Lcm=jwLcm,從關系式中是(shi)太(tai)特(te)丑(chou)出(chu),在必定速度(du)的(de)(de)燥音(yin)(yin)污染,磁(ci)環(huan)(huan)的(de)(de)電(dian)(dian)感(gan)(gan)(gan)越(yue)大(da)更好。但(dan)合(he)理時候未必太(tai)過,正是(shi)因為合(he)理的(de)(de)磁(ci)環(huan)(huan)上(shang)(shang)和(he)內(nei)寄(ji)生電(dian)(dian)解電(dian)(dian)容(rong)器(qi),它的(de)(de)來源于(yu)策(ce)略是(shi)與電(dian)(dian)感(gan)(gan)(gan)串并聯。當(dang)碰上(shang)(shang)中頻干(gan)(gan)預網(wang)絡(luo)(luo)數(shu)(shu)據(ju)時,電(dian)(dian)解電(dian)(dian)容(rong)器(qi)的(de)(de)容(rong)抗較小,將磁(ci)環(huan)(huan)的(de)(de)電(dian)(dian)感(gan)(gan)(gan)短路等問題,才能(neng)(neng)使共(gong)(gong)(gong)(gong)模(mo)扼(e)流(liu)圈(quan)失卻能(neng)(neng)力(li)。
