Würth Elektronik offers free EMI filter design tool

Simulation platform REDEXPERT extended

Waldenburg (Germany), January 13, 2022—REDEXPERT from Würth Elektronik is a precise simulation platform based on measured values that supports the component manufacturer's customers in selecting suitable components. Now, with the EMI Filter Designer, a user-friendly function for developing filters against electromagnetic interference has been added. In the first version of the tool, which will be continuously expanded, discrete low-pass EMI filters for conducted differential interference can be developed, such as those needed for DC-DC converters.

After entering the input specifications, the REDEXPERT EMI Filter Designer calculates the optimal capacitors and inductors and outputs a suitable circuit topology. This allows the user to directly benefit from the know-how of the EMC consultants at Würth Elektronik who designed this tool. The EMI Filter Designer is available for free use at http://redexpert.we-online.com. Free samples of the suitable components determined with the tool can be ordered directly from this for prototyping.
