MEM2012W241R

(1/2) 3-terminal Filters(SMD) For Wide-band Conformity to RoHS Directive MEM Series MEM2012W Type These SMD Type 3-terminal filters are used for elimination of high frequency noise from signal lines. Due to a higher cutoff frequency than earlier SMD type 3-terminal filters and steep attenuation characteristics, these filters are effective for elimination of a high level of high frequency noise. FEATURES • Steeper and wider bandwidth attenuation characteristics than earlier type. • Used for high cutoff frequency applications. • Small size (2.0× 1.25× 2.0mm). • Entirely monolithic architecture. • Taped-type packaging, so can be used for automatic mounting. PACKAGING STYLE AND QUANTITIES Packaging style Taping Quantity 1000 pieces/reel APPLICATIONS Signal line noise elimination for PCs, liquid crystal panels, printers, game machines, cellular phones, DVCs, etc. TEMPERATURE RANGES Operating/Storage –40 to +85°C SHAPES AND DIMENSIONS/CIRCUIT DIAGRAM/RECOMMENDED PC BOARD PATTERN 2±0.2 0.1 2 IN/OUT 1 IN/OUT GND NC 1.25±0.2 NC 0.4 1.6 3 0.2min. 2±0.2 Marking Dimensions in mm 0.3±0.2 0.4±0.2 0.3±0.2 Weight: 22mg typ.
