Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. PA1005.020 becomes PA1005.020T). Pulse complies to industry standard tape and reel specification EIA481. 6. To order RoHS compliant part, add the suffix "NL" to the part number (i.e. PA1005.020 becomes PA1005.020NL and PA1005.020T becomes PA1005.020NLT). Please note that the PA1005.125 part is not available in an RoHS compliant version. NOTES: 1. 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 when both one turn windings connected in parallel. 3. To calculate value of terminating resistor (Rt) use the following formula: Rt (Ω) =VREF * N / (Ipeak_primary) 4. The peak flux density of the device must remain below 2000 Gauss.
