(Unit: mm)
FEATURES 特長
 Miniature size: 2520 footprint (2.5mm×2.0mm) and low
profile(1.2mm Max. height)
 The use of magnetic iron powder ensure capability for
large current.
 The use of Flat wire for Low DC resistance.
 Optimization of Electrode for More Low DC resistance.
 Magnetically shielded, low audible core noise.
 Reflow solderable.
 Operating temperature : -40~+125°C
 Halogen Free, RoHS compliant.
 小型薄型構造 (2.5x2.0mm角、高さ1.2mm Max.)
 磁性材に鉄系磁性粉を用いた大電流対応
 平角線採用による低直流抵抗
 電極構造最適化による、更なる低直流抵抗
 閉磁路構造、低コア鳴きノイズ
 リフロはんだ対応
 動作温度範囲:-40~+125°C
 ハロゲンフリー、RoHS指令対応

(1) Inductance is measured with a LCR meter 4284A (Agilent
Technologies) or equivalent. Test frequency at 1MHz
(2) DC resistance is measured with 34420A (Agilent Technologies) or
3541(HIOKI). (Reference ambient temperature 20°C)
(3) Maximum allowable DC current is that which causes a 30%
inductance reduction from the initial value, coil temperature to rise
by 40
C whichever is smaller.
(Reference ambient temperature 20°C)
