With the increasing importance of power quality, TDK is focusing on AC filtering solutions. They are available with different terminal configurations and electrical parameters. Thanks to their simple design (round winding in an aluminum can), these widely used components offer high reliability at the same time. TDK portfolio features two basic AC filter capacitor designs: single-phase and three-phase capacitors. When AC capacitors are used as filters, they suppress harmonic distortions and reactive power problems, thus improving power quality and reliability.
