(Unit: mm)
• Low profile (4.0mm Max. square,1.5/1.8/2.0mm Max. height).
• Magnetically shielded construction and low DC resistanse.
• Ideal for DC-DC converter choke coil for portable equipments
(DVD, DSC, Cellular phone, PDA).
• RoHS compliant.
• 小型薄形構造(4.0mm角Max. 高さ1.5/1.8/2.0mmMax.)
• 閉磁路構造、低直流抵抗
• 小型機器（DVD, DSC, Cellular phone, PDA）などのDC-
DCコンバータ用チョークコイルに最適
• RoHS指令対応
