Coilcraft New High-isolation, Low-loss Current Sense Transformers

CSX7045 Series

SMT Current Sense Transformers

The CSX7045 series is a high-isolation, low-loss current sensing transformer designed for high-performance power electronics and automotive applications. It features a compact chip-style package with a low 5.3 mm profile, delivering 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 1:250 provides excellent design flexibility, while bandwidth up to 800 kHz enables accurate high-frequency current measurement in fast-switching systems such as DC-DC converters, motor drives, inverters, and power management circuits. Offering 1800 Vrms isolation, the CSX7045 is ideal for demanding automotive environments.

• Very low primary DC resistance
• Designed for use up to 800 kHz
• 1800 Vrms, one minute isolation (hipot) between primary and secondary
• Qualified based on AEC-Q200 Rev E
  • Solderability: Tested per J-STD-002, Method S1 and Method D
