Temperature rise is 55C in typical buck or boost circuits operating at 300kHz with the rated Idc current and reference ET applied to the inductor. 2. Total loss in the inductor is 1.8W for 55C temperature rise above ambient. 3. In high volt-time applications, additional heating in the component can occur due to core losses in the inductor which may necessitate derating the current in order to limit the temperature rise of the component. In order to determine the approximate total losses (or temperature rise) for a given application, both copper and core losses should be taken into account. Temp. Rise Factor Connection (K3) Estimated Temperature Rise: Trise = K3 * (Coreloss(W) + Copperloss(W)).833 (C) CopperLoss = Irms2 * DCR_Typical (m) / 1000 CoreLoss = K2 * (Freq_kHz)1.26 * (B)2.11 B = K1 * Volt-sec * 100 4. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. P0595 becomes P0595T). Pulse complies to industry standard tape and reel specification EIA481. 5. To order RoHS compliant part, add the suffix "NL" to the part number (i.e. P0595 becomes P0595NL and P0595T becomes P0595NLT). 6. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
