SMT Current Sense Transformers PL1170 Maximum Reflow Temperature: 235�C Storage Temperature: -55�C to +135�C Moisture Sensitivity Level (MSL): 3 Height: 7.1mm Max Footprint: 14.6mm x 12.6mm Max Current Rating: up to 15 A Can be made available in a RoHS configuration by a special request (Sn100 lead finish) Frequency Range: 50kHz to 500kHz Electrical Specifications @ 25°C - Operating Temperature -40°C to +125°C DCR (mΩ MAX) Part Number Turns Ratio Current Rating (A) Secondary Inductance (mH MIN) Primary (1, 3-2, 4) Secondary (5-6) Hipot (Vrms) PL1170 1:1:100 15 14.8 1.5 930 500 Notes: 1. The temperature of the component (ambient temperature plus the 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 air flow when both single turn windings connected in parallel. 3. To calculate the value of the terminating resistor (Rt), use the following formula: Germany 49 7032 7806 0 1 Bpk = 14.29 * Vref * (Duty_Cycle_Max) * 10 5 ( N * Freq_kHz) * for bi-polar current applications divide Bpk as calculated above by 2. 5. Optional Tape & Reel can be ordered by adding a “T” suffix to the part number (i.e. PL1170 becomes PL1170T). Rt Ω = VREF * N / (Ipeak_primary) USA 858 674 8100 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 formula below: Singapore 65 6287 8998 pulseelectronics.com Shanghai 86 21 62787060 China 86 755 33966678 Taiwan 886 3 4356768 M133.C (12/11) SMT Current Sense Transformers PL1170 Mechanical Schematic PL1170 1 DATE CODE COUNTRY OF ORIGIN US PAT 5309130 12,45 ±0,38 5 2 3 4 6 10,15 ±0,38 12,57 12,45 ±0,38 For More Information Pulse Worldwide Headquarters Two Pearl Buck Court Bristol, PA 19007 U.S.A.
