SMT CURRENT SENSE TRANSFORMERS PA0368 Series Current rating up to 4 Amps Operating Frequency Range: 50 kHz to 500 kHz Maximum footprint: 8.38 mm x 8.38 mm x 3.30 mm Electrical Specifications @ 25°C — Operating Temperature -40°C to 130°C Part number Turns ratio Current Rating1 PA0368.050 PA0368.070 PA0368.080 PA0368.100 PA0368.125 1:50 1:70 1:80 1:100 1:125 4 4 4 4 4 Secondary Inductance (mH MIN) 1.7 3.3 4.3 6.7 10.4 DCR (mΩ MAX) Primary Hipot (Vrms) Secondary 4 4 4 4 4 900 1200 1400 1600 1900 500 500 500 500 500 NOTES: 1. The maximum current rating is based on temperature rise of the component and represents the dc current which will cause a typical temperature rise of 40°C with no airflow. 2. To calculate the value of the terminating resistor (Rt) use the following formula: Rt (Ω) = Vref * N / (Ipeak primary) 3. The peak flux density of the device must remain below 2000 Gauss. To calculate the peak flux density for a uni-polar current, use the following formula: Bpk = 64.9 * Vref * (Duty Cycle Max) * 105 / (N * Freq kHz) — (for bi-polar current applications divide Bpk as calculated above by 2).
