∗1 Rated current based on inductance variation: Current when inductance decreases by 30% of the initial value due to direct current superimposed
characteristics
∗2 Rated current based on increasing product temperature: Current when temperature of the product reaches +40°C
∗3 Rated current based on inductance variation: Current when inductance decreases by 10% of the initial value due to direct current superimposed
characteristics
∗4 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)
