DCR (m Max) Part 5,6 Number The temperature of component (ambient temperature plus temper-ature rise) must be within the specified operating temperature range. 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 40C with no airflow when both one turn windings connected in parallel. To calculate value of terminating resistor (Rt) use the following formula: Rt (W) = Vref * N / (Ipeak_primary) The peak flux density of the device must remain below 2000 Gauss. To calculate the peak flux density for uni-polar current use following formula: Bpk = 37.59 * Vref * (Duty_Cycle_Max) * 105 / (N * Freq_kHz) * for bi-polar current applications divide Bpk (as calculated above) by 2. 1 power.pulseelectronics.com 5. 6. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. PA1005.020QNL becomes PA1005.020QNLT). Pulse complies to industry standard tape and reel specification EIA481. The "NL" suffix indicates an RoHS-compliant part number.
