FEATURES/特 長
Low profile (3.5mm Max. square, thickness : 1.7mm Max.
height).
Features an open magnetic circuit, but its thin dimensions
result in minimum leakage flux and result in minimum
electromagnetic interference generated.
RoHS compliant.
小型薄½構造(3.5mm角Max.、高さ1.7mm Max.)
開磁路だが厚さが非常に薄い為、漏れ磁束が少なく外部への
½響が少ない
RoHS指令対応

(1) Inductance is measured with a LCR meter 4284A* or equivalent.
(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 )
