The maximum current rating is based on temperature rise of the component PA0368.050NLT). Pulse complies to industry standard tape and and represents the DC current which will cause a typical temperature rise reel specification EIA481. of 40°C with no airflow. 5. The "NL" suffix indicates an RoHS-compliant part number. Non-NL 2. To calculate the value of the terminating resistor (Rt) use the following suffixed parts are not necessarily RoHS compliant, but are electriformula: Rt (Ω) = VREF * N / (Ipeak primary) cally and mechanically equivalent to NL versions. If a part number 3. The peak flux density of device must remain below 2000 Gauss. does not have the "NL" suffix, but an RoHS compliant version is To calculate the peak flux density for a uni-polar current, use the following required, please contact Pulse for availability. formula: Bpk = 64.9 * VREF * (Duty Cycle Max) * 10 5 / (N * Freq kHz) 6. The temperature of the component (ambient plus temperature rise) *for bi-polar current applications divide Bpk (as calculated above) by 2. must be within the stated operating temperature range. 4.
