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 500 KHz. Core does not saturate abruptly. The ET and DC current are limited by the desired inductance and temperature rise. The temperature rise is directly proportional to the total watts loss (I2R plus core loss). The core loss (mW/cc) 4. equals 9.07 x 10-10 f1.26 B2.11. B is the operating flux density (Gauss) due to ripple voltage and f is the operating frequency (Hertz) of the ripple current. Optional 13" Tape & Reel packaging can be ordered by adding a “T” suffix to the part number, (i.e. PE-53600T).
