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 55C. 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
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).
