New Version of the Würth Elektronik Component Selector Software Released

Feb4_Wurth_Component_SelectWürth Elektronik eiSos has released a revised an expanded version of the Component Selector. Six new modules have been added to the four existing ones, making this selection tool one of the world’s most comprehensive component databases to be provided by a single manufacturer.

In the field of EMC components, cable ferrites and common mode chokes are now available in addition to PCB ferrites. These modules allow users to analyze and compare technical values and impedance curves for all products. Within the component characteristic curve, filters help users find the right components quickly and easily.

In the power inductors module, the right inductor for non-insulated DC/DC converters can easily be determined. The Component Selector also calculates wire and core losses and, based on these losses, calculates the temperature increase of the component. In the field of power supplies, there is also a module to help quickly and easily configure flexible transformers for isolated DC/DC converters to suit the relevant input and output values. For use in active PFC circuits, there is now also a module for determining the right PFC choke.

The most significant extension of the software is for signal and communications products. As well as the existing RF inductor module for selecting components according to frequency, for adjusting antenna for example, three further modules have now been introduced.

A particularly practical addition is the module for discrete LAN transformers or integrated RJ45 LAN transformers, which enables users to search and filter components by the internal connections or land pad. This means that the right solutions for existing products can be found in no time at all.

Users can also save and store existing settings for component selection. Within all the modules, the relevant data sheet can also be consulted online and S-parameters can be downloaded. The integrated online update function ensures that the product database is kept up to date at all times.

Users without an internet connection can get updates from the manufacturer’s website at any time and install them manually. The Component Selector is designed to be self-explanatory and easy to navigate.

Users can install the free Component Selector by downloading the software from More information on
