大功率分流器

Bourns 提供採用金屬合金元件製造的高功率分流電阻器,該元件透過電子束焊接到鍍錫銅端子上。 Bourns® CSM 系列具有三種不同的占地尺寸: 8518、7036 和 6918 公制,電阻值低至 50 µΩ,滿足低電壓降和高精度要求,能夠處理高達 1,000 A 的大電流和高達 50 W 的永久額定功率。

CSM 系列符合 AEC-Q200,具有高脈衝功率額定值。金屬合金電流感測元件允許低至 0.25 µV/K 的 熱EMF 和 50 PPM/°C 的低 TCR,我們的客戶發現它們特別適合於高溫波動的汽車應用。

Bourns® CSM 大功率電流分流器非常適合電池管理系統應用。正確的電池管理要求持續監控流經電路的電流。 在使用可充電電池的汽車及其他市場領域,監控電池狀態至關重要。使用 Bourns® CSM 系列進行電池管理,可提供一種非常準確且經濟高效的方法以滿足該等需求。

 

特徵
尺寸 6918, 7036, 8518
70 °C 時的額定功率
36 W 至 50 W
電阻範圍 25 至 200 µΩ
电阻公差 ±5 %
溫度係數(電阻材料) <50 ppm/°C
工作溫度範圍 –55 to +170 °C

根據要求,Bourns 可提供定制零件,以滿足客戶所需的形狀、機械及電氣特性。可使用額外敲擊焊接電流感測引腳,以將電流檢測電阻器正確連接至電路板上。在分流器和電流測量芯片組之間保持電流感應走線/導線盡可能短,對於測量精度非常重要。這就是為何 Bourns 透過將分流器集成到電路板中的預組裝模塊以為客戶提供支援的原因,該模塊可根據客戶要求納入附加組件,如連接器接頭和 NTC 熱敏電阻。

所有經批准用於典型汽車應用的 Bourns® 組件均在經過 TS 16949 全面認證的設施中製造,並已透過無源組件的 AEC-Q 標準進行測試與鑒定,還通過 PPAP 呈現給客戶以供選擇與批准。Bourns 還為客戶提供訪問我們應用程式測試實驗室的權限。

Bourns 長期以來以優質的產品服務於汽車市場。Bourns 憑藉出色的客戶服務和現場應用工程師服務,與汽車系統設計師緊密合作,為客戶提供佈局支援,並根據客戶要求進行修改。 Bourns 憑藉出色的客戶服務和現場應用工程師服務,與汽車系統設計師緊密合作,為客戶提供佈局支援,並根據客戶要求進行修改。 Bourns 執行浪湧測試,並提供應用程式和客戶特定測試。
