Notes: (1) Inductance values are rated at -40°C to +130°C operating temperature range with rated DC current flowing and
the operating ETop across the inductor.
(2) ETop is rated at 500 kHz except where designated otherwise.
(3) The control values of inductance are measured at the operating flux 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.
