4.8 Max.
• 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.
小型薄形構造 (4.8mm角Max.、高さ1.2 mm Max.)
• 開磁路だが厚さが非常に薄いため、漏れ磁束が少なく外部への影
響が少ない
• 携帯電話に要求される1.5メートルからコンクリート床への
自由落下衝撃試験をクリア
RoHS指令対応

(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)
*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。
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℃上昇の何れか小さい値です。
(周囲温度20℃を基準とする。)
