The temperature of component (ambient temperature plus temper-ature rise) must be within the specified operating temperature range. 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 40°C with no airflow. 7. The PM2165.XXXNL part numbers are AEC-Q200 and IATF16949 certified. The mechanical dimensions are 100% tested in production but do not necessarily meet aproduct capability index (Cpk) >1.33 and therefore may not strictly conform to PPAP. 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 density for uni-polar current use following formula: Bpk = 37.59 * Vref * (Duty_Cycle_Max) * 10[5] / (N * Freq_kHz) - for bi-polar current applications divide Bpk (as calculated above) by 2. 5. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number (i.e. PA1005.020NL becomes PA1005.020NLT). Pulse complies to industry standard tape and reel specification EIA481. 6. The “NL” suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are not necessarily RoHS compliant, but are electrically and mechanically equivalent to NL versions. If a part number does not have the “NL” suffix, but an RoHS compliant version is required, please contact Pulse for availability.
