SMT CURRENT SENSE TRANSFORMERS P822X Series Height: 5.1mm Max Footprint: 8.4mm x 7.2mm Max Current Rating: up to 10A Frequency Range: 50kHz to 1MHz Reverse Polarity version of P820X Electrical Specifications @ 25C -- Operating Temperature -40C to +130C Part Number P8222 P8223 P8224 P8225 P8226 P8227NL P8228NL P8229 Turns Ratio Current Rating 2 (A) Secondary Inductance (mH MIN) 1:20 1:30 1:40 1:50 1:60 1:70 1:100 1:125 10 10 10 10 10 10 10 10 0.08 0.18 0.32 0.50 0.72 0.98 2.00 3.00 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) DCR (m MAX) Primary Secondary (8-7) (6-4) 6 6 6 6 6 6 6 6 550 870 1140 1500 1750 4750 5500 6500 Schematic .190 4,83 NOM .330 8,38 MAX Pin 8 3 4 2 5 1 6 Pin 7 500 500 500 500 500 500 500 500 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: Bpk = 37.59 * Vref * (Duty_Cycle_Max) * 105 / ( N * Freq_kHz) * for bi-polar current applications divide Bpk as calculated above by 2. 5. Add "T" suffix to the part number for Tape & Reel packaging, (i.e. P8222T). 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 availabili- Mechanical .010 0,25 Hipot (VRMS) .284 7,21 MAX .073 1,85 6 7 4 Iprimary .073 1,85 NOM .050 1,27 8 Isecondary 1 .050 1,27 N RT Vref APPLICATION CIRCUIT .120 RECOMMENDED 3,05 PAD LAYOUT .024 0,61 BOTTOM VIEW For More Information: .106 2,69 .100 2,54 .060 1,52 Pulse Worldwide Headquarters Pulse European Headquarters Pulse China Headquarters 12220 World Trade Dr. San Diego, CA 92128 U.S.A. www.pulseeng.com Einsteinstrasse 1 D-71083 Herrenberg Germany TEL: 858 674 8100 FAX: 858 674 8262 TEL: 49 7032 7806 0 FAX: 49 7032 7806 12 B402, Shenzhen Academy of Aerospace Technology Bldg. 10th Kejinan Rd.
