Optional Tape & Reel packaging can be ordered by the current in order to limit the temperature rise of the adding a suffix to the part number (i.e. P1166.102NL component. In order to determine the approximate total becomes P1166.102NLT).

The saturation current, Isat, is the current at which the component inductance drops by the indicated 1.23 2.38 percentage (typical) at an ambient temperature of Core loss = K1 x f (kHz) x Bac(Ga) (mW) 25C. This current is determined by placing the component in the specified ambient environment and Bac (peak to peak flux density) = K2 x I (Ga) applying a short duration pulse current (to eliminate = K2/L(H) x Et(V-Sec) (Ga) self-heating effects) to the component. where f varies between 25kHz and 1MHz, and Bac is 7.
