Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. PA0273NL becomes PA0273NLT). Pulse complies with industry standard tape and reel specification EIA481. The tape and reel for this product has a width (W=44mm), pitch (Po=32mm) and depth (Ko=11.78mm). 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. PR ELI MI NA RY 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-µsec applications, it is important to calculate the core loss of the transformer. Approximate transformer core loss can be calculated as: CoreLoss (W) = 1.32E-13 * (Freq_kHz)1.63 * (ΔB_Gauss)2.63 where ΔB can be calculated as: For Flyback Topology: ΔB = K1_Factor * Δ(A) For Forward Topology: ΔB = K1_Factor * Volt-µsec Mechanical .860 MAX 21,84 12 12 Date Code Country of Origin 1 6 .590 14,99 1.190 30,23 .930 23,62 1.150 29,21 MAX Part Number 12X .028 0,71 .118 3,00 7 7 1 12X .060 1,52 .118 3,00 12-PIN SMT 6 .590 14,99 SUGGESTED PAD LAYOUT .450 MAX 11,43 .010 ± .002 0,25 ± 0,05 .006 /0,15 12 SURFACES 12X .080 2,03 For More Information: Pulse Worldwide Headquarters Pulse European Headquarters Pulse China Headquarters 12220 World Trade Dr. San Diego, CA 92128 U.S.A. www.pulseeng.com Einsteinstrasse 1 D-71083 Herrenberg Germany TEL: 858 674 8100 FAX: 858 674 8262 TEL: 49 7032 7806 0 FAX: 49 7032 7806 12 B402, Shenzhen Academy of Aerospace Technology Bldg. 10th Kejinan Rd.
