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

메모

When ordering, please specify packaging code: e.g. CSX7045-250RC
Inductance is measured at 100 kHz, 0.1 Vrms, 0 ADC on an Agilent 4263B (or equivalent) with a Coilcraft CCF1546 test fixture.
DCR is measured on a Keithley 580 Micro-ohmmeter (or equivalent).
Volt-time product is for the secondary, between pins 3 and 4.
Primary current that causes a 40°C rise from 125°C.
Terminating resistance (R_T) value is based on 1 Volt output with 20 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
R_T (Ohms) = V_out × N_sec / I_in.
1800 Vrms, one minute isolation (hipot) between primary and secondary.
