1. Temperature rise is 55°C in typical buck or boost circuits operating
at 300kHz with rated Idc current and reference ET applied to inductor.
Estimated Temperature Rise:
Trise = K3 * (Coreloss(W) + Copperloss(W).833 (C)
CopperLoss = Irms2 * DCR_Typical (mΩ) / 1000
CoreLoss = K2 * (Freq_kHz)1.26 * (ΔB)2.11
ΔB = K1 * Volt-µsec * 100
2. Total inductor loss 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.
4.Optional Tape & Reel packaging can be ordered by adding a "T"
suffix to the part number (i.e. PL8304 becomes PL8304T). Pulse
complies to industry standard tape and reel specification EIA481.
