※ The saturation current value is the DC current value having inductance decrease down to 30%.(at 20℃)
※ The temperature rise current value is the DC current value having temperature increase up to 40℃. (at
20℃)
※ The rated current is the DC current value that satisfies both of current value saturation current value and
temperature rise current value.
