  • With UL material or UL approval on request

Technical data:
  • Structure and mounting according to customer requirements
    • Mounting bracket
    • Spacer bolts
    • Connection clamps
    • stranded wire connections / wire connections
    • horizontal / vertical version
    • built into the housing
    • open version
    • potted version
    • Version with transformer plate for frequency ranges from 50Hz to 900Hz
    • Version with strip material for frequency ranges from 50Hz to 15,000Hz

  • Ambient temperature -40°C to 40°C (higher on request)
Application:
  • Mains choke
  • Smoothing 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 EI125_125_26
