WF WE-CLFS Line Filters Passive Components Owner’s Manual

 

1. Single Phase Line Filter

 

2. Internal Schematic

 

3. General Information

Rated current of the mains filter :
Must be equal to or greater than the current requirements of the connected devices.
For ambient temperatures above 40 °C, the following derating curve applies.

 

4. ATTENUATION FOR DIFFERENT INDUCTANCE VALUES AND TOPOLOGIES:

 

Attenuation plots for the examined filters with system impedances of 50 Ω and 50 Ω. You can simulate these plots and many more with our REDEXPERT online tool.

 

5. Influence of the System Impedances

 

6. Filter Selection with REDEXPERT

Selection Guide:

• Choose rated current
• Check frequency range of the noise
• Check attenuation in this frequency range
• Choose maximal allowed leakage current

Take the different system impedances in consideration.

 

7. Interesting: Leakage Current

For low leakage requesting applications, we offer a low leakage version without Y capacitors.

 

8. Placement and Grounding
