NOTES:
1. 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

ΔB
= K1 * Volt-µsec * 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.
