The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range. 3. Pri/Lk. Inductance value is measured at 100Khz/0.1Vrms. 4. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part standard tape and reel specification EIA481. 5. 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) 6. 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 * (∆B_Gauss)2.63 where ∆B can be calculated as: For Flyback Topology: ∆B = K1_Factor * ∆(A) 7.
