Toroidal chokes

Standards:

  • Structure according to DIN EN 61558/VDE 0570

  • Sizes according to DIN EN 50081-1/-2

  • CE marking

  • ROHS-compliant

  • aWith UL material or UL approval on request

Technical data:
  • Design and mounting according to customer requirements
    • Open design
    • stranded wire connections/wire connections
    • horizontal/vertical design
    • built into the housing
    • open variant
    • potted version
    • Ferrite core choke
    • Pure iron choke
    • Frequency ranges up to 100kHz (ferrite up to 300kHz)
  • Insulation class B=130°C (F=155°C on request)
  • Ambient temperature -40°C to 40°C (higher on request)
Application:
  • PFC choke
  • Current-regulated choke (2 windings)
  • Mains choke
  • Smoothing choke
  • Storage choke
Size:

The size results from the energy of the choke (E = L * I²), the desired current and desired inductance can be freely selected.

Example:
  • Desired inductance value: 2mH
  • Desired current value: 15A
  • Results in an energy of 225mWs = size EI84_43
