On-Board Type (DC) EMI Suppression Filters (EMIFILr)
Chip Common Mode Choke Coils Winding Type DLW21S/DLW21H/DLW31S Series
DLW21S Series
Features
1. DLW21S series realizes small size and low profile.
2.0x1.2x1.2mm
2. High common mode impedance at high frequency
effects excellent noise suppression performance.
3. Various common mode impedance items of 67 to 370ohm
can be used, considering noise level and signal
frequency.
4. DLW21S series enables noise suppression for
differential signal line without distortion in
high speed signal transmission due to its high
coupling.
5. Lead is not contained in the product.
6. Small dimension enables higher density packaging.
Applications
1. USB lines of PC, Peripheral equipment.
2. LVDS lines of Note-PC, LCD.
3. USB lines of Small digital AV equipment such as
digital camera.
