Low-Loss Storage Chokes

Advantages:

  • low magnetic scatter field
  • low power loss through the use of different core materials like: Powder, HiFlux, MPP or KoolMy cores, tape-wound core and cut tape-wound cores as well as pot and block cores
  • with inductivity values from 1 µH and currents up to 1,000A, chokes for frequencies up to 1 MHz can be realised

Structural shapes in the versions:

  • with pins (THT), SMD

Windings according to requirement:

  • round and flattened wire
  • HF-stranded wire

Advantages of a flattened wire edgewise wound winding:

  • optimum usage of the winding space; in the case of chokes of edgewise-would flattened copper strands, the efficiency is improved and a high current load, e.g. in high-capacity PFCs is made possible
  • single-layer winding - high resonance frequencies are reached with this

Applications:

  • Switching regulator IC's, like Linear Technology, National Semiconductor, On Semiconductor, STMicroelektronics, Texas Instruments and Fairchild
  • in switched mode power supplies, inverters and voltage transformers
