Notes: (1) Inductance values are rated at -40°C to +130°C operating temperature range with rated DC current ?owing and the operating ET op across the inductor.

(2) ET op is rated at 500 kHz except where designated otherwise.

(3) The control values of inductance are measured at the operating ?ux density equal or less than 10 gauss and without DC current.

(4) ETop is rated at 250 kHz.

(5) ETop is rated at 150 kHz.
