KLL chokes

High power, high performance, low losses

Our high performance chokes were developed par­ticularly for applications demanding a high efficiency and a compact design.

The Kaschke Low Loss Series features a high ripple current with small energy dissipation. Due to the low hysteresis, the chokes provide low loss solutions for applications such as Power Factor Correction and High DC bus voltage boost chokes e.g. in zero current switching mode and Resonant Chokes.

By using the Kaschke KLL chokes you gain the advantage of similar Sendust or MPP solutions, but at a far more competitive price.

Outstanding characteristics

  • small hyteresis losses (also suitable for very high ripple currents)
  • low parasitic capacity
  • good EMV characteristics
  • chokes available with auxiliary winding
  • typical inductance values from 50 μH to 1 mH at application frequencies within the range of 30 kHz to 300 kHz and up to 15 A.
