SMT CURRENT SENSE TRANSFORMERS PB002X Series Height: 10mm Max Footprint: 19.9mm x 14.5mm Max Current Rating: up to 35A Frequency Range: 50kHz to 500kHz Electrical Specifications @ 25C -- Operating Temperature -40C to +130C DCR (m MAX) Part 5,6 Number Turns Ratio Current 2 Rating (A) Secondary Inductance (mH MIN) Primary (11-12) Secondary (2-4) Hipot (VRMS) PB0025 50:1 35 1.4 2.8 700 500 PB0026 100:1 35 5.6 2.8 1400 500 PB0027 200:1 35 22.4 2.8 2900 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 40C with no airflow when both one turn windings connected in parallel. 3. To calculate the value of the terminating resistor (Rt) use the following formula: Rt () = 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 = 8.0 * 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. PB0025 becomes PB0025T). 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 part no. (i.e. PB0025 becomes PB0025NL and PB0025T becomes PB0025NLT).
