SMT CURRENT SENSE TRANSFORMERS For DC/DC Converter Applications Primary rated for 10 amps Full selection of turns ratios Pick and place compatible Optimal performance @ 100 kHz and above Low profile - height is .19" (4,83 mm) Electrical Specifications @ 25°C — Operating Temperature -40°C to +130°C Pulse Number P8202T P8203T P8204T P8205T P8206T P8207T P8208T P8209T Ls1 (µH) 80 180 320 500 720 980 2000 3000 Turns ratio 1:20 1:30 1:40 1:50 1:60 1:70 1:100 1:125 Rs (Ω MAX) 0.55 0.87 1.14 1.50 1.75 4.75 5.50 6.50 Terminating Resistor2 (Ω) 2.0 3.0 4.0 5.0 6.0 7.0 10.0 12.5 HiPot (Vrms) 500 500 500 500 500 500 500 500 NOTES: 1. Inductance at 0.1 Vac, 10 kHz. 2. Terminating resistor for 1 V out with 10 amps peak in the primary. 3. The operating temperature range includes the ambient temperature and the temperature rise. 4. The temperature rise of the component is calculated based on the total core and copper loss: Copper loss (W) : Pcu = (Ipk/Ns)2*(Dmax/3)*Rs. Core loss (W) : Pfe=1.3*10-17*f(Hz)1.63*B(Gauss)2.45 Bmax(Gauss) = 3.75*109*(Ipk*Rt/Ns+Vd)*Dmax/(k*Ns*f), where f is in Hz, k=1 for unipolar and 2 for bipolar waveform. Keep Bmax below 2000 Gauss. Temperature rise (°C): ~300*(Pcu+Pfe) 5. Reverse polarity parts are available for all turns ratios : P8222T through P8229T.
