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) = 4.6E-14 * (Freq_kHz)1.63 * (DB_Gauss)2.63 where DB can be calculated as: For Flyback Topology: DB = K1_Factor * D(A) For Forward Topology: DB = K1_Factor * Volt-µsec 5. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number (i.e. PA0476NL becomes PA0476NLT). 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. AR Mechanical LIM IN 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) PR E * * Please note height PN PA1039NL is 8.9mm (0.35”) Max For More Information Pulse Worldwide Headquarters 12220 World Trade Drive San Diego, CA 92128 U.S.A.
