LI2 rating is the ability of the inductor to store energy. 1. To prevent excessive temperature rise, limit ETOP to the rated ETOP specified. This is not a saturation limit. Temperature rise of inductors 2 is 40°C MAX at MAX current and rated ETOP. 4. Design control test voltage is critical. Inductance increases with voltage. 2. A 2:1 nominal inductance swing from no IDC to operating IDC gives 5. RoHS compliant parts are available. Order RoHS compliant parts by adding improved protection against current discontinuities at light loading. the suffix "NL" to the part number (i.e. PE-51506 becomes PE-51506NL). Inductance increases with greater ETOP. Reference values occur at IDC and low flux density.
