(Unit: mm)
(1) Inductance is measured with a LCR meter 4284A (Agilent
Technologies) or equivalent.
(2) DC resistance is measured with 34420A (Agilent Technologies) or
3541(HIOKI). (environment temp. of 25°C)
(3) Inductance Decrease Current based upon 20% inductance reduction
from the initial value.
(4) Temperature Rise Current based upon 40°C temperature rise.
(Reference ambient temperature 25°C)
(5) Absolute maximum voltage 30VDC.
(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。
(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℃)
(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20%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℃上昇する値
(周囲温度25℃を基準とする。)
(5)絶対最大電圧 30VDC
Inductance Range:
0.68~8.0µH
