New WE-CLFS S-Parameters Extend Down to 5 Hz for Greater Design Accuracy!

Designing for low-frequency performance just got easier. Würth Elektronik has released improved S-Parameter files for its WE-CLFS Line Filter Series, now starting at just 5 Hz. This update provides significantly more accurate modeling across the entire frequency spectrum.

What’s New?

  • No interpolated values in the lower frequency range up to 10 kHz
  • Detection of the real filter characteristic by measurements from a frequency of 5 Hz

Why It Matters:

  • Interpolation related deviations are corrected
  • More reliable low-frequency simulation results
  • Better prediction of EMC behaviour
  • Improved design accuracy for sensitive applications

New SPICE Models Available:

  • Updated models reflect the new measurements
Diagram about common mode insertion loss

Line Filter Topologies

In line filters, different stages can be distinguished. Single stage filters offer attenuation of up to 75 to 80dB. In the improved single-stage filter, an additional X-capacitor provides better suppression of differential mode noise. The highest common and differential mode attenuation is offered by the two-stage filter, which includes an additional common mode choke and another X-capacitor.
