1. Reference values are for an inductor with a 55°C temperature rise. The core loss is 10%
of the copper loss at the ET listed and 500kHz.
2. Core does not saturate abruptly. The ET and DC current are limited by the desired
inductance and temperature rise.
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)
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” sux to the part
number (i.e. P0595NL becomes PO595NLT). Pulse complies to industry standard tape
and reel specification EIA481.
5. The “NL” sux indicates an RoHS-compliant part number. Non-NL suxed parts are
not necessarily RoHS compliant, but are electrically and mechanically equivalent to
NL versions. If a part number does not have the “NL” sux, 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.
