SMT CURRENT SENSE TRANSFORMERS PE-68XXX Series Height: 7.1mm Max Footprint: 14.6mm x 12.6mm Max Current Rating: up to 15A Frequency Range: 50kHz to 500kHz Electrical Specifications @ 25°C — Operating Temperature -40°C to +130°C Part 5,6 Number Current 2 Rating (A) Turns Ratio DCR (mΩ MAX) Secondary Inductance (mH MIN) Primary (1,3-2,4) Hipot (VRMS) Secondary (5-6) PE-68210 1:1:50 15 3.8 1.15 380 500 PE-68280 1:1:100 15 14.8 1.15 930 500 PE-68383 1:1:200 15 59.2 1.15 3900 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 (Ω) = 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. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. PE-68210 becomes PE-68210T). Pulse complies to industry standard tape and reel specification EIA481. 6. RoHS compliant parts are being introduced. Please contact Pulse for RoHS compliant part availability. If available, order part by adding “NL” to the part number (i.e. PE-68210 becomes PE-68210NL and PE-68210T becomes PE-68210NLT).
