Notes:
1. Temperature rise is 55°C in typical buck or boost circuits operating at 300kHz with the 5. The “NL” suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are
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.
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.
Estimated Temperature Rise:
Trise = K3 * (Coreloss (W) + Copperloss (W)).833 (C)
CopperLoss = Irms2 * DCR_Typical (mΩ) / 1000
CopperLoss = 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 PO595NLT). Pulse complies to industry standard tape
and reel specification EIA481.
