SMT Current Sense Transformers PL1170 Maximum Reflow Temperature: 235C Storage Temperature: -55C to +135C Moisture Sensitivity Level (MSL): 3 Height: 7.1mm Max Footprint: 14.6mm x 12.6mm Max Current Rating: up to 15 A Can be made available in a RoHS configuration by a special request (Sn100 lead finish) Frequency Range: 50kHz to 500kHz Electrical Specifications 25C - Operating Temperature -40C to +125C DCR (m MAX) Part Turns Current Rating Secondary Inductance Hipot Number Ratio (A) (mH MIN) Primary (1, 3-2, 4) Secondary (5-6) (Vrms) PL1170 1:1:100 15 14.8 1.5 930 500 Notes: 1. The temperature of the component (ambient temperature plus the temperature rise) 4. The peak flux density of the device must remain below 2000 Gauss. To calculate the peak must be within the specified operating temperature range. flux density for a uni-polar current use the formula below: 2. The maximum current rating is based upon temperature rise of the component and represents the dc current which will cause a typical temperature rise of 40C with no Bpk = 14.29 * Vref * (Duty Cycle Max) * 10 5 ( N * Freq kHz) air flow when both single turn windings connected in parallel. * for bi-polar current applications divide Bpk as calculated above by 2. 3. To calculate the value of the terminating resistor (Rt), use the following formula: 5. Optional Tape & Reel can be ordered by adding a T suffix to the part number (i.e. Rt = VREF * N / (Ipeak primary) PL1170 becomes PL1170T).
