SMT CURRENT SENSE TRANSFORMERS Maximum Reflow Temperature: 235°C (245°C for RoHS compliant) Storage Temperature:-55°C to +130°C Moisture Sensitivity Level(MSL):1 Can be made available in a RoHS configuration by special request (Sn100 lead finish) Electrical Specifications @ 25°C — Operating Temperature -40°C to +130°C Part5,6 Number Turns Ratio Current Rating (A) Secondary Inductance (mH MIN) DCR Primary (1,3-2,4) (mΩ MAX) DCR Secondary (5-6) (mΩ MAX) Hipot PL1961 1:1:200 15.00 59.200 2.30 4200.0 500 NOTES: 1.The temperature of the component (ambient temperature plus temperature rise) must be within the specified operating temperature range. 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 40°C with no air flow when both one turn windings connected in parallel. 3.To calculate the value of the terminating resistor (Rt) use the following formula: Rt (W) =Vref * N / (Ipeak_primary) 4.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 = 14.29 * Vref * (Duty_Cycle_Max) * 105 / ( N * Freq_kHz) * for bi-polar current applications divide Bpk as calculated above by 2. 5.For RoHS compliant parts add suffix NL to the part number. 6.Add T suffix to the part number for tape and reel packaging.
