Innovative online tool: The fast and easy way to find the right snubber capacitor

Posted on 17 February 2019

  TDK Corporation presents the EPCOS Snubber Cap Finder – an innovative online tool that simplifies and speeds up the search for suitable snubber capacitors to protect IGBT modules against voltage peaks. With Snubber Cap Finder, the user only has to enter the manufacturer's IGBT code number in the search mask, and the integrated database, [...]

EMC filters: LeaXield™ minimizes earth leakage currents

Posted on 20 November 2019

  TDK Corporation presents the EPCOS LeaXield™ active filter module – a completely new solution for the minimization of earth leakage currents in power drive systems with frequency converters. Leakage current can cause RCDs (residual current device) to trip. In some applications this means that RCDs with low thresholds such as 30 mA cannot be [...]
