(1) Inductance is measured with a LCR meter 4284A (Agilent
Technologies) or equivalent.
Test frequency at 100kHz
(2) DC resistance is measured with 34420A (Agilent Technologies) or
3541(HIOKI). (Reference ambient temperature 25°C)
(3) Inductance Decrease Current based upon 30% inductance
reduction from the initial value
(4) Temperature Rise Current based upon 40°C temperature rise.
(Reference ambient temperature 20°C)
(1) インダクタンスはLCRメータ4284A(Agilent Technologies)
または同等品により測定する。
測定周波数は100kHz。
(2) 直流抵抗は測定器34420A(Agilent Technologies)または3541
(HIOKI)と同等品により測定する。(周囲温度25°C)
(3) 直流重畳許容電流:直流重畳電流を流した時インダクタンスの値
が初期値より30%減少する直流電流値
(4) 温度上昇許容電流:コイルの温度が40°C上昇する値
(周囲温度20°Cを基準とする。)
