Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. PA0700NL becomes PA0700NLT). Pulse complies with 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. AR Y 1. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range. 2. The above transformers and inductors have been tested and approved by Pulse's power IC partners and are sited in the appropriate datasheet or evaluation board documentation at these companies. To determine which IC and IC partners are matched with the above Pulse part numbers please consult the IC Cross Reference on the Pulse website. 3. For flyback topology applications, it is necessary to ensure that the transformer will not saturate in the application. The peak flux density (Bpk) should remain below 2700Gauss. To calculate the peak flux density use the following formula: Bpk (Gauss) = K1_Factor * Ipk(A) 4. In high volt-sec applications, it is important to calculate the core loss of the transformer. Approximate transformer core loss can be calculated as: CoreLoss (W) = 2.98E-13 * (Freq_kHz)1.63 * (DB_Gauss)2.63 IN Mechanical IM EL PR For More Information: Pulse Worldwide Headquarters Pulse European Headquarters TEL: 858 674 8100 FAX: 858 674 8262 TEL: 49 7032 7806 0 FAX: 49 7032 7806 12 12220 World Trade Dr. San Diego, CA 92128 U.S.A. www.pulseeng.com Einsteinstrasse 1 D-71083 Herrenberg Germany Pulse China Headquarters B402, Shenzhen Academy of Aerospace Technology Bldg. 10th Kejinan Rd.
