大功率分流器

Bourns 提供使用金属合金元件制造的高功率分流电阻器,该元件通过电子束焊接到镀锡铜端子上。Bourns® CSM 型号系列具有三种不同的占地尺寸: 8518、7036 和 6918 公制,电阻值低至 50 µΩ,可满足低电压降和高精度要求,能够处理高达 1000 A 的大电流和高达 50 W 的永久额定功率。

CSM 系列符合 AEC-Q200,具有高脉冲功率额定值。金属合金电流感测元件允许低至 0.25 µV/K 的热 EMF 和 50 PPM/°C 的低 TCR,我们的客户发现它们特别适合于高温波动的汽车应用。

Bourns® CSM 大功率电流分流器非常适合电池管理系统应用。正确的电池管理要求持续监控流经电路的电流。在使用可充电电池的汽车及其他市场领域,监控电池状态至关重要。使用 Bourns® CSM 系列进行电池管理,是满足这些需求的一种非常准确且经济高效的方法。

 

特性
尺寸 6918, 7036, 8518
70°C 时的额定功率 36 W 至 50 W
电阻范围 25 至 200 µΩ
电阻公差 ±5 %
温度系数(电阻材料) <50 ppm/°C
工作温度范围 –55 to +170 °C

根据要求,Bourns 可以提供定制零件,以满足客户所需的形状、机械和电气特性。可以使用额外敲击焊接电流感应针,以将电流感应电阻器正确连接到电路板上。在分流器和电流测量芯片组之间保持电流感应走线/导线尽可能短,对于测量精度非常重要。这就是为什么 Bourns 为客户提供支持,通过将分流器集成到电路板中的预组装模块的原因,该模块可以根据客户要求纳入附加组件,例如连接器接头和 NTC 热敏电阻。

所有批准用于典型汽车应用的 Bourns® 组件均在经过 TS 16949 全面认证的设施中制造,并已使用无源组件的 AEC-Q 标准进行测试与鉴定,通过 PPAP 呈现给客户选择和批准。Bourns 还为客户提供权限,可访问我们的应用程序测试实验室。

Bourns 长期以来以优质的产品服务于汽车市场。Bourns 凭借出色的客户服务和现场应用工程师服务,与汽车系统设计师紧密合作,为客户提供布局支持,并根据客户要求进行修改。Bourns 执行浪涌测试,并提供应用程序和客户定制测试。
