Notes
1. Tolerance ± 10% for L > 10 µH, ± 20% for L ≤ 10µH
2. Inductance at 0.5V, 100kHz
3. Irated (permanent DC) without heatsink ;
With heatsink I = Irated x 1.4
4. Typical inductance value at recommended full load
5. Ipeak max= maximum peak value of current at
+100°C; L value not guaranteed
6. 40% admissible Iripple over Irated at f=200 kHz
