(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) Maximum allowable DC current is that which causes a 30%
inductance reduction from the initial value, or coil temperature to
rise by 40°C, whichever is smaller. (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) 最大許容電流は、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、または直流電流により、
コイルの温度が40°C上昇の何れか小さい値。（周囲温度20°Cを
基準とする。）
