2.適宜的電源電壓和負(fù)載電路及工作溫度是霍爾器件正常工作的先決條件，霍爾器件的供電電壓，負(fù)載電流及工作溫度不得超出規(guī)格書中多規(guī)定的范圍。 </p> <p> 3.所用工具，特別是焊接用的電烙鐵，必須嚴(yán)格接上地線，以保證電烙鐵不漏電，即電烙鐵的鐵皮是接地的，比較好選用低壓恒溫可調(diào)電烙鐵進(jìn)行焊接。 </p> <p> 4.所有設(shè)備都應(yīng)嚴(yán)格接地，并用檢電筆逐個查明確無漏電，才能開始工作。 </p> <p> 5.要求印制板及霍爾器件管腳嚴(yán)格經(jīng)過清潔處理，使它與焊錫有良好的浸潤性。無錫單極霍爾開關(guān)霍爾元件,華芯多年專業(yè)做霍爾,大品牌值得信賴,精選各類霍爾元件,好評如潮,庫存充足!霍爾元件一站搞定。</p><div

1、霍爾系數(shù)RH（又稱霍爾常數(shù)）在磁場不太強(qiáng)時，霍爾電勢差UH與激勵電流I和磁感應(yīng)強(qiáng)度B的乘積成正比，與霍爾片的厚度δ成反比，即，式中的RH稱為霍爾系數(shù)，它表示霍爾效應(yīng)的強(qiáng)弱。另即霍爾常數(shù)等于霍爾片材料的電阻率ρ與電子遷移率μ的乘積。2、霍爾靈敏度KH（又稱霍爾乘積靈敏度）霍爾靈敏度與霍爾系數(shù)成正比而與霍爾片的厚度δ成反比，即，它通?？梢员碚骰魻柍?shù)。3、霍爾額定激勵電流當(dāng)霍爾元件自身溫升10℃時所流過的激勵電流稱為額定激勵電流。4、霍爾比較大允許激勵電流以霍爾元件允許比較大溫升為限制所對應(yīng)的激勵電流稱為比較大允許激勵電流。5、霍爾輸入電阻霍爾激勵電極間的電阻值稱為輸入電阻。6、霍爾輸出電阻霍爾輸出電極間的電阻值稱為輸出電阻。7、霍爾元件的電阻溫度系數(shù)在不施加磁場的條件下，環(huán)境溫度每變化1℃時，電阻的相對變化率，用α表示，單位為%/℃。 </p><p> 造成霍爾開關(guān)失效的常見原因有哪些？我們在使用霍爾開關(guān)的過程中經(jīng)常會遇到霍爾工作了一段時間之后就停止工作的情況，這時，霍爾芯片可能是被損壞了，那是什么原因?qū)е碌哪?？可以從以下幾個方面來入手分析檢測：1.首先檢查外部電路，是否有虛焊漏焊的情況造成短路、斷路的現(xiàn)象。2.開關(guān)類的霍爾一般都需要外接一個上拉電阻才可以正常工作，檢查下電阻是否正常。3.單獨檢查下磁鐵，有些磁鐵存在時間過長使磁鐵消磁，導(dǎo)致霍爾感應(yīng)不到，無法正常工作。（注：霍爾與磁鐵之間有阻隔也會減弱磁場）4.是否超出了霍爾本身的溫度范圍，溫度過高會導(dǎo)致霍爾損壞，也會導(dǎo)致磁鐵消磁。5.檢查電壓、電流是否穩(wěn)定，是否在霍爾參數(shù)規(guī)定范圍內(nèi)，偏上限或下限會造成霍爾不穩(wěn)定，超出參數(shù)范圍會導(dǎo)致霍爾被瞬間擊穿造成損壞。我司擁有世界前列霍爾元件研發(fā)設(shè)計能力,與多家**科學(xué)研究院建立合作關(guān)系。</p><div
