FEATURES/特 長
Low profile (4.8mm Max. square, 1.2.mm Max. height).
Features an open magnetic circuit, but its thin dimensions
result in minimum leakage flax and result in minimum
electromagnetic interference generated.
Clears free-fall drop tests in which it is dropped onto a
concrete floor from a height of 1.5m, thus meeting
requirements specified for use in cellular phones.
RoHS compliant.

(1) Inductance is measured with a LCR meter 4284A * or equivalent.
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, 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* 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、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。
(周囲温度20℃を基準とする。
