The temperature of component (ambient temperature plus temper-ature rise) must be within the 5. Optional Tape & Reel packaging can be ordered by adding a T suffix to the part number (i.e. specified operating temperature range. PA1005.020QNL becomes PA1005.020QNLT). Pulse complies to industry standard tape and reel specification EIA481. 2. 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 6. The NL suffix indicates an RoHS-compliant part number. windings connected in parallel. 3. To calculate value of terminating resistor (Rt) use the following formula: Rt (W) = Vref * N / (Ipeak primary) 4. The peak flux density of the device must remain below 2000 Gauss. To calculate the peak flux den- sity for uni-polar current use following formula: 5 Bpk = 37.59 * Vref * (Duty Cycle Max) * 10 / (N * Freq kHz) * for bi-polar current applications divide Bpk (as calculated above) by 2.
