Estimated Temperature Rise:
NOTES:
Trise = K3 * (Coreloss(W) + Copperloss(W).833 (C)
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.
CopperLoss = Irms2 * DCR_Typical (mΩ) / 1000
CoreLoss = K2 * (Freq_kHz)1.26 * (ΔB)2.11
ΔB = K1 * Volt-µsec * 100
2.Core does not saturate abruptly. The ET and DC current are
limited by the desired inductance and temperature rise.
4.Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part
number (i.e. PE-53600NL becomes PE-53600NLT). Pulse complies to industry
standard tape and reel specification EIA481.
3.In high volt-time applications, additional heating in the compo-
nent can occur due to core losses in the inductor which may
necessitate derating the current in order to limit the tempera-
ture rise of the component. In order to determine the approxi-
mate total losses (or temperature rise) for a given application,
both copper and core losses should be taken into account.
5. The "NL" suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are
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.
