用 固定インダクタ
(1) Inductance is measured with a LCR meter 4284A * or equivalent.
(2) DC resistance is measured with a Digital Multimeter TR6871
(Advantest) or equivalent.
(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)
* Agilent Technologies
(1) インダクタンスはLCRメータ4284A * または同等品により測定する。
(2) 直流抵抗はデジタルマルチメータTR6871(Advantest)または同等品
により測定する。
(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℃上昇の何れか小さい値です。
(周囲温度20℃を基準とする。)
