Temperature rise is 55°C 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 55°C 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. Estimated Temperature Rise: Trise = K3 * (Coreloss(W) + Copperloss(W)).833 (C) Temp. Rise Factor Connection (K3) CopperLoss = Irms2 * DCR_Typical (mΩ) / 1000 CoreLoss = K2 * (Freq_kHz)1.26 * (ΔB)2.11 ΔB = K1 * Volt-µsec * 100 4. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. P0595NL becomes P0595NLT). Pulse complies to industry standard tape and reel specification EIA481. 5. 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. 6. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
