Product descriptionWith the increasing importance of power quality, TDK focuses on AC filtering solutions. These modular capacitors are offered in single-phase and three-phase designs with various terminal configurations and electrical parameters. Customized mechanical and electrical designs enable compact layouts and high reliability adapted to system constraints. When used as AC filters, the capacitors reduce harmonic distortion and manage reactive power to improve overall power quality and system robustness.
