Switching Mode Transformers EEL12 Platforms - THT Mechanicals PG1054.XXXNL NOTES: 1. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range. 2. For flyback technology applications, it is necessary to ensure that the transformer will not saturate in the application. The peak flux density (Bpk) should remain below 2700 Gauss. To calculate the peak flux density, use the following formula: Bpk (Gauss) = K1_Factor * Ipk(A) 3. 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) = 1.98E-07 X (Freq_kHz)ˆ1·38 X (DB_Gauss)ˆ2·86 where DB can be calculated as: For Flyback Topology: DB = K1_Factor * 0.59Ipk(A) 4. 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 availabilty. 5. Full pins is available.
