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). Pulse complies with industry loss (or temperature rise) for a given application, both standard Tape and Tape & Reel specification EIA481. copper losses and core losses should be taken into 3. TheN suffix indicates an RoHS-compliant part account. number. Non-NL suffixed parts are not necessarily RoHS compliant, but are electrically and mechanically equivalent to NL versions.

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. The heating current, Idc, is the DC current required less than 2500 Gauss. to raise the component temperature by the indicated K2 is a core size and winding dependant value and delta (approximately).
