Frako Power Electronics Capacitors Type LKT-F



Frako Power Electronics Capacitors; the Safer, Stronger Capacitor for Power Quality Filters. 

Hans von Mangoldt logo

Frako Type LKT-F capacitors are power electronic capacitors which are designed specifically for use with non-sinusoidal voltage and current including Pulse Width Modulated (PWM) voltage.  Type LKT-F capacitors may be used in various types of filters for use at the input or output side of inverters and drives. They may be applied in either switched (PWM) DC (VN ratings) or AC (Vrms ratings) filter circuits. Frako offers both single-phase and 3-phase capacitors. Frako Power Electronics Capacitors are UL certified and comply with IEC Standard 61071.

        • Over-voltage tolerance
        • Current-carrying capacity
        • Thermal endurance   


      • Frako LKT-F capacitors include Four-Fold safety features such as: all 3 phases disconnect at over-pressure,  self-healing, segmented metallized film, dry-type no leak capacitors (with only a thin film of oil applied to metallized film where it is most beneficial), Contact Ring spot-welded for increased reliability eliminating damage during production and offering Lead-Free capacitors.  The cylindrical design uses optimized geometrical shape and conforms to industry best practices for internal heat dissipation.
      • Secure, maintenance-free terminals, which offer anti-vibration connections and maintain terminal pressure for the lifetime of the capacitor, are factory installed on all LKT-F capacitors.
