∗1 Rated current: Value obtained when current flows and the temperature has risen to 40°C or when DC current flows and the nominal value of inductance
has fallen by 30%, whichever is smaller.
∗2 Inductance is at 1/2 Idc1 power distribution. The L vaule at 0A is higher than the guaranteed performance.
• Operating temperature range: –40 to +105°C (Including self-temperature rise)
