Hilo-Test ISM 5P/20 current-viewing resistor (current shunt)

Brand: HILO TEST

Origin: Germany

ISM 5P/20 是 HILO-TEST ISM 系列双同轴结构脉冲电流观测电阻（Current-Viewing Resistor），用于快上升沿电流脉冲的峰值与波形精确测量：峰值电流 5 kA、连续 RMS 20A、标称阻值 20mΩ。双同轴设计在 -3dB 上限频率以下表现为纯直流电阻，阻值频率无关，对噪声与电磁干扰不敏感；最大 RMS 电流由耗散功率决定，最大峰值电流由脉冲负载积分 ∫i²dt 决定（按 100K 温升标定）。输出经 BNC 取电压信号，电压信号在额定电流下即波形成比例复现。ISM 系列以高带宽、低上升时间与高阻值精度见长，是雷电冲击（1.2/50μs）、浪涌、大电流脉冲校准测量的基准器件。
