These current sense transformers have two one turn primaries that can be 5. The temperature rise of the component is calculated based on the total core loss used in parallel. The listed current ratings are for parallel connection. and copper loss: 2 2. The reference values are for an application using the termination resistor A. To calculate total copper loss (W): P(cu) = Ipk * Req * Ff * don where Ff is 1 for (Rt) and operating with unipolar waveform at 100kHz, 40% duty cycle. unipolar waveform and 2 for bipolar waveform 1.67 The estimated temperature rise is 55°C. B. To calculate total core loss (W): P (core) = 0.000073 * (Freq. in kHz) * (Bop in 2.532 3. The peak flux density should remain below 2100 Gauss to ensure that the kG) where: Bop in kG = Kb * Ipk * Rt * don/(2000 * Freq. in kHz) core does not saturate. Use the following formula to calculate the peak C. To calculate temperature rise: Temperature Rise (C) = 60.18 * (Core Loss (W) + .833 flux density: Bpk = Kb * Ipk * Rt * don/(Ff * freq. in kHz) where: Rt is the Copper Loss (W)) terminating resistor in the application and the 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 -D %Droop = (1-e ) * 100 USA 858 674 8100 Germany 49 7032 7806 0 Singapore 65 6287 8998 Shanghai 86 21 62787060 China 86 755 33966678 Taiwan 886 3 4356768 1 pulseelectronics.com P516.C (06/15) THT Current Sense Transformers Mechanical Schematic PXXXX .810 .580 MAX MAX 20,57 14,73 .750 MAX 19,05 P058X Date Code Country of Origin .130 3,30 .700 17,78 3 Weight ..................................................5 grams 10 7 1 4 Tray ........................................................20/tray .350 Inches (6X) .040 Dimension: 8,89 mm .010 Unless otherwise specified, all tolerances are ± 7 10 0,25 14 .200 8 5,08 SUGGESTED PCB HOLE PATTERN For More Information Pulse Worldwide Pulse Europe Pulse China Headquarters Pulse North China Pulse South Asia Pulse North Asia Headquarters Einsteinstrasse 1 B402, Shenzhen Academy of Room 2704/2705 135 Joo Seng Road 3F, No. 198 12220 World Trade Drive D-71083 Herren- Aerospace Technol- Super Ocean Finance #03-02 Zhongyuan Road San Diego, CA berg ogy Bldg.
