THT CURRENT SENSE TRANSFORMERS UL/C-UL recognized components 3000Vrms gate to drive winding test Useful operating frequency from 50kHz to 500kHz Most popular winding configurations Electrical Specifications @ 25°C — Operating Temperature -40°C to 130°C 6 Part Number Turns Ratio Primary Inductance (1-10) (mH MIN) DCR Pri (1-10) (Ω MAX) DCR Sec1 (3-7) (mΩ ±15%) DCR Sec2 (4-8) (mΩ ±15%) Hi-Pot (Pri-Sec) (Vrms) P0581 P0582 P0583 200:1:1 100:1:1 50:1:1 76 19 5 2.8 1.4 0.7 1.7 1.7 1.7 1.7 1.7 1.7 3000 3000 3000 Additional Specifications Part Number RT P0581 P0582 P0583 200 100 15 Reference Data Ipk Droop (Amps) (%) 34 1.00 35 1.98 36 1.19 NOTES: 1. These current sense transformers have two one turn primaries that can be used in parallel. The listed current ratings are for parallel connection. 2. The reference values are for an application using the termination resistor (Rt) and operating with unipolar waveform at 100kHz, 40% duty cycle. The estimated temperature rise is 55°C. 3. The peak flux density should remain below 2100 Gauss to ensure that the core does not saturate. Use the following formula to calculate the peak flux density: Bpk = Kb * Ipk * Rt * don/(Ff * Freq. in kHz) where: Rt is the terminating resistor in the application and Ff is 1 for unipolar waveform and 2 for bipolar waveform Calculation Data Max Flux Density 2000 2000 2000 17.12 68.49 273.97 4. To calculate the droop: Droop Exponent (D) = Rt * don/(Lpri in mH * Freq. in kHz) %Droop = (1-e-D) * 100 5. The temperature rise of the component is calculated based on the total core loss and copper loss: A. To calculate total copper loss (W): P(cu) = Ipk2 * Req * Ff * don where: Ff is 1 for unipolar waveform and 2 for bipolar waveform B. To calculate total core loss (W): P(core) = 0.000073 * (Freq. in kHz)1.67 * (Bop in kG)2.532 where: Bop in kG = Kb * Ipk * Rt * don/(2000 * Freq. in kHz) C. To calculate temperature rise: Temperature Rise (C) = 60.18 * (Core Loss(W) + Copper Loss (W)).833 6. To order RoHS compliant part, add the suffix "NL" to the part number (i.e. P0581 becomes P0581NL).
