Notes:
1. The max ET is calculated to limit the core loss and temperature rise at 100KHz based
on a bipolar flux swing of 2100Ga Peak. This value needs to be derated for higher
frequencies using the temperature rise calculation.
2. The temperature rise of the component is calculated based on the total core loss and
copper loss:
3. ANL versions, which use triple insulated wire on both the drive and gate windings, are
compliant with IEC 60950, IEC 61558, IEC 61010 & IEC 60601 for reinforced insulation.
NL versions, which use triple insulated wire on just the drive winding, comply with basic
insulation requirements.
4. 12mm package creepage distance satisfies IEC60950-1 & IEC61558-1/-2-16 reinforced
insulation requirements for working voltage to 600Vrms max, OVC II, Pollution Degree 2
and altitude up to 2000m.
5. Unless otherwise specified, all testing is made at 100kHz, 0.1VAC.
6. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number
(i.e. PH9400.111NL becomes PH9400.111NLT). Pulse complies to industry standard tape and
reel specification EIA481.
A. To calculate total copper loss (W), use the following formula:
Copper Loss (W) = Irms2 * (DCR_Drive + (# of Gates) * DCR_Gates)
B. To calculate total core loss (W), use the following formula:
Copper Loss (W) = 5.1E-10 * (Frequency in kHz)1.42 * (K1 * ET) 2.5
Where ET = (V * Duty Cycle) / Frequency
C. To calculate temperature rise, use the following formula:
Temperature Rise (C) = 71 * (Core Loss(W) + Copper Loss (W))
