SMT Current Sense Transformers Height: 5.1mm Max* Footprint: 8.4mm x 7.2mm Max Current Rating: up to 20A Frequency Range: 50kHz to 1MHz Low Primary DCR version of P820X Lead Finish: Sn63/Pb37 Electrical Specifications @ 25°C - Operating Temperature -40°C to +130°C Part Number Turns Ratio Current 2 Rating (A) PL2035 1:50 20 5 Notes: 1. The temperature of 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 airflow when both one turn windings connected in parallel. 3. To calculate value of 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 uni-polar current use following formula: DCR (mΩ MAX) Secondary Inductance (mH MIN) Primary (8-7) Secondary (1-3) Hipot (VRMS) 0.5 0.75 1500 500 5 Bpk = 37.59 * VREF * (Duty_Cycle_Max) * 10 / (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. PL2035 becomes PL2035T). Pulse complies to industry standard tape and reel specification EIA481.
