SMT Current Sense Transformers PB002XNL Series Height: 10mm Max Footprint: 19.9mm x 15.0mm Max Frequency Range: 50kHz to 500kHz Current Rating: up to 35A Electrical Specifications @ 25C - Operating Temperature -40C to +130C DCR (m MAX) Part Number Turns Ratio Secondary Inductance (mH MIN) PB0025NL 50:1 1.4 0.42 700 500 PB0026NL 100:1 5.6 0.42 1400 500 PB0027NL 200:1 22.4 0.42 2900 500 5,6 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 uni-polar current use following formula: Primary (11-12) Secondary (2-4) 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 & Packaging can be ordered by adding a "T" suffix to the part number (i.e. PB0025NL becomes PB0025NLT). Pulse complies to the industry standard tape and reel specification EIA481. 6. The "NL" suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are not necessarily RoHS compliant, but are electrically and mechanically equivalent to NL versions. If a part number does not have the "NL" suffix, but an RoHS compliant version is required, please contact Pulse for availability.
