Land Pattern
Tolerance: M: ± 20%.
Small size, low profile.
Impedance range: from 67Ω to 370Ω.
High common mode impedance at high frequency effects.
Excellent noise suppression performance.
Temperature rise: 15ºC at rated current on 25ºC ambient.
Operating temperature: From –40ºC to +85°C.
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.
