TDK Corporation presents the EPCOS Snubber Cap Finder, an online tool that simplifies and speeds up the search for suitable snubber capacitors to protect IGBT modules against voltage peaks. Upon entering the manufacturer's IGBT code number in the search mask, the integrated database, covering over 1000 IGBT modules from major suppliers, locates the appropriate capacitors.

Alternatively, the search can be made by entering the voltage, capacity, capacitor type or terminal configuration. The search is then supported with technical drawings of the selected terminal configuration, an overview of the key technical data and the link to the corresponding data sheets. The tool is available from TDK's website - click here.

The EPCOS snubber capacitors are currently available in 17 different terminal configurations. The series, ranging from B32656S* to B32686S*, are characterised by their high pulse strength and reliability of the contacts. In addition, the components offer extremely low ESL values. The tin-plated copper straps have hole spacings ranging from 19.5 to 63mm. These snubber capacitors cover a range of voltages from 850 to 2000VDC and capacitances from 68nF to 5.6µF. All types are designed for temperatures of up to +110°C.
