Test Conditions

Ipk1: 10A for 0.47uH, 3.5A for 1uH.

Ipk2: 12A for 0.47uH, 6.0A for 1uH.

ACR: 1MHz, w/o DC bias.

Isat: DC current at which the inductance drops 30% from its nominal value at 25°C.

Irms: DC current that causes the temperature rise (ΔT, approximate 40 ˚C) from 25°C ambient.

Rated voltage: 40V

Operating Temperature: -40˚C ~ +150˚C. (including self-temperature rise)

Storage Condition: -40˚C ~ +150˚C (on board), -10˚C ~ +40˚C (with packaging) and R.H. 70% Max.

AMELH4018S Series is RoHS Compliant and Pb free.
