Temperature rise is 55°C in typical buck or boost circuits operating 2 CopperLoss = Irms * DCR_Typical (mΩ) / 1000 at 300kHz with the rated Idc current and reference ET applied to the 1.26 2.11 CoreLoss = K2 * (Freq_kHz) * (ΔB) inductor. ΔB = K1 * Volt-µsec * 100 2. Total loss in the inductor is 1.8W for 55°C temperature rise above 4.Optional Tape & Reel packaging can be ordered by adding a "T" ambient. suffix to the part number (i.e. P0595NL becomes P0595NLT). Pulse 3.In high volt-time applications, additional heating in the component complies to industry standard tape and reel specification EIA481. can occur due to core losses in the inductor which may necessitate 5. The "NL" suffix indicates an RoHS-compliant part number. Non-NL derating the current in order to limit the temperature rise of the suffixed parts are not necessarily RoHS compliant, but are electrically component. In order to determine the approximate total losses and mechanically equivalent to NL versions. If a part number does (or temperature rise) for a given application, both copper and core not have the "NL" suffix, but an RoHS compliant version is required, losses should be taken into account. please contact Pulse for availability. 6. The temperature of the component (ambient plus temperature rise) Estimated Temperature Rise: .833 must be within the stated operating temperature range.
