smt Current Sense Transformers P820X Series Height: 5.5mm Max Footprint: 8.4mm x 7.2mm Max Current Rating: up to 10A Frequency Range: 50kHz to 1MHz Lower Primary DCR version available: PA1005.XXX series Electrical Specifications @ 25°C — Operating Temperature -40°C to +130°C Part 6,7 Turns Number Ratio Current 2 Rating (A) Secondary Inductance (mH MIN) DCR (mW MAX) Primary (8-7) Secondary (1-3) Hipot (VRMS) 550 500 P8202NL 1:20 10 0.08 6 P8203NL 1:30 10 0.18 6 870 500 P8204NL 1:40 10 0.32 6 1140 500 P8205NL 1:50 10 0.50 6 1500 500 P8206NL 1:60 10 0.72 6 2250 500 P8207NL 1:70 10 0.98 6 4750 500 P8208NL 1:100 10 2.00 6 5500 500 P8209NL 1:125 10 3.00 6 6500 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 airflow 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 uni-polar current use following formula: Mechanical Bpk = 37.59 * Vref * (Duty_Cycle_Max) * 105 / ( N * Freq_kHz) * for bi-polar current applications divide Bpk (as calculated above) by 2. 5.Part numbers P8222 to P8229 are reverse polarity versions of P820X. 6. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number (i.e. P8202NL becomes P8202NLT). Pulse complies to industry standard tape and reel specification EIA481. 7. 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.
