線圈長度為55mm
2. 寬工作溫度-40°C至+125°C
3. 額定電流6000Apk
4. 線圈絕緣1.3kVpk
5. 峰值di/dt能力高達(dá)100kA/us
6. 薄型1.2mm橫截面直徑
高頻帶寬(-3dB)20MHz
7. 屏蔽“HF”版本，橫截面直徑為1.7mm
出色的耐壓能力，高頻帶寬(-3dB)30MHz
二、產(chǎn)品應(yīng)用
1. 電力電子電路中的開關(guān)電流波形，例如：
（1）小至TO-220、D2PAK的MOSFET或IGBT功率器件或其他SMT功率器件
（2）測量半導(dǎo)體中的功率損耗
（3）監(jiān)測小型電感器、電容器、緩沖電路等中的電流
2. 在存在大直流電流的情況下測量小交流電流（例如監(jiān)測電容器紋波）
3. 電源轉(zhuǎn)換器開發(fā)和診斷
4. 測量從工頻到射頻應(yīng)用中的高頻正弦電流、脈沖電流或瞬態(tài)電流
三、標(biāo)準(zhǔn)與合規(guī)性
1. CE 標(biāo)志
2. 符合 EMC EN61326-1
3. 符合 IEC 61010-1;IEC 61010-2-032 標(biāo)準(zhǔn)
4. PEM Ltd 已通過 ISO9001：2015 標(biāo)準(zhǔn)認(rèn)證
5. 專利產(chǎn)品
