The CSX7030-100RC is a surface-mount current sense transformer with a 1:100 turns ratio, designed for automotive applications requiring high isolation and low loss. It stands 3.3 mm tall and features 1000 Vrms, one-minute isolation between primary and secondary, AEC-Q200 qualification, and a maximum operating temperature of +140°C. The primary DC resistance is 0.52 mΩ, and it supports currents up to 20 A with less than 40°C temperature rise from 25°C ambient. The device is RoHS compliant, halogen-free, and packaged in tape and reel for automated assembly. Operating frequency ranges from 12 kHz to over 1000 kHz, with a volt-time product of 1000 Vµsec on the secondary.
The CSX7030 series is a high-isolation, low-loss current sensing transformer designed for high-performance power electronics and automotive applications. It features a small chip-style package with an ultra-low 3.3 mm profile and is manufactured using a highly automated process to ensure consistent quality and cost efficiency.
With very low DCR, the series minimizes conduction losses and self-heating, making it ideal for high-current applications up to 20 A. A wide range of turns ratios from 1:50 to 1:200 provides excellent design flexibility, while bandwidth up to and beyond 1 MHz enables accurate high-frequency current measurement in fast-switching systems such as DC-DC converters, motor drives, inverters, and power management circuits. The CSX7030 is AEC-Q200 qualified, making it suitable for demanding automotive applications.
