NOTES:
±
3. LI rating is the ability of the inductor to store energyꢀ
1. To prevent excessive temperature rise, limit ETOP to the rated ETOP
specifiedꢀ This is not a saturation limitꢀ Temperature rise of inductors
±
is 42°C MAX at MAX current and rated ETOP
ꢀ
4. Design control test voltage is criticalꢀ Inductance increases with voltageꢀ
5. RoHS compliant parts are availableꢀ Order RoHS compliant parts by adding
the suffix "NL" to the part number (iꢀeꢀ PE-51526 becomes PE-51526NL)ꢀ
2. A ±:1 nominal inductance swing from no IDC to operating IDC gives
improved protection against current discontinuities at light loadingꢀ
Inductance increases with greater ETOPꢀ Reference values occur
at IDC and low flux densityꢀ
