The CSX7030-200 is a surface-mount current sense transformer with a 1:200 turns ratio, designed for high-current sensing up to 20 A in automotive applications. It measures 7.20 mm by 5.20 mm by 3.31 mm and features a maximum DC resistance of 0.52 mΩ on the primary side and a terminating resistance of 10.0 Ω for a 1 V output at 20 A primary current. The transformer offers 1000 Vrms isolation for one minute between primary and secondary windings, operates at ambient temperatures from -40°C to +125°C, and is AEC-Q200 qualified. It is packaged in tape and reel for automated assembly, with MSL 1 moisture sensitivity and compliance with RoHS and halogen-free standards.
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.
