!Note
1. Small size and low profile (2.0x1.2x0.9mm).
2. High common mode impedance at high frequency
3. Various common mode impedance from 67 to 180 ohm
4. Suitable for differential signal line like USB2.0,
5. Small dimension enables higher density mounting
Common mode noise suppression of signal lines in high
speed and high density digital equipment such as PCs
and peripherals and telecommunications equipment.
