Recommended Land Pattern Tolerance: M: 20%. Small size, low profile. Impedance range: from 67 to 370. High common mode impedance at high frequency effects. Excellent noise suppression performance. Temperature rise: 15C at rated current on 25C ambient. Operating temperature: From -40C to +85C. D. Applications: 1. Common mode noise suppression of signal lines in high speed and high-density digital equipment, such as personal computers and peripherals. 2. Suitable for differential signal line such as USB2.0, IEEE1394 and LVDS, capable of high speed signal transmission without distortion due to its high coupling. Note: For "LEAD FREE" / "RoHS" parts, we add "-LF" / "-LFR" after the part number. SMD wire wound Common Mode Chip Inductor: P/N SCM2012F-I-series July 01, 2006.
