The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range. 2. 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 2600Gauss. 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 trans- former. Approximate transformer core loss can be calculated as: CoreLoss (W) = 3.84E-14 * (Freq_kHz)1.63 * (ΔB_Gauss)2.63 where ΔB can be calculated as: For Flyback Topology: ΔB = K1_Factor * ΔI(A) 4. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part standard tape and reel specification EIA481. The tape and reel for this product has a width (W=24mm), pitch (Po=16mm) and depth (Ko=5.8mm). Notes:
