(1) Inductance is measured with a LCR meter 4284A * or equvalent.

Test frequency at 100kHz

(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, coil temperature to rise

by 40℃, whichever is smaller.

(Reference ambient temperature 20℃)

(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。

測定周波数は100kHzです。

(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½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½れか小さい値です。
