Notes

Connections

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

I ripple

+100°C; L value not guaranteed

6. 40% admissible Iripple over Irated at f=200 kHz
