How to build filter designs for input filters quickly and inexpensively?

@askLorandt explains: Design Kit Design your EMC Filter

This video explains how to use the Design Your EMC Filter Design Kit from Würth Elektronik with an input filter for an AC/DC or DC/DC switching regulator to quickly and inexpensively design a suitable filter design. Such a filter can already be purchased, but its flexibility is very limited.

With the help of the Design Kit from Würth Elektronik eiSos, an individual filter can be built according to your needs. The Kit contains various chokes, various connectors, resistors, capacitors and circuit boards. It is possible to work with different capacitors and inductors depending on the noise level or frequency.

Lorandt simulates the construction of a board with a resistor, Y-capacitor, connector and a current compensated choke.
