Common Mode Chokes for Enhanced EMC Performance
Common mode chokes (CMC) are components that intervene on EMC noise flowing on cables or PCB nets.
These CMCs are essentially used on power lines, both AC and DC. As any electronic circuit needs a power supply our range of CMCs can be designed for any application and across any industry or market. CMCs are made of a high permeable magnetic core with 2 or more identical windings, but a single core (usually ferrite cores or Nanocrystalline) surrounding two wires can also make a single turn CMC.
We offer a huge variation of products from single cores to highly compact ferrite-based CMC, to customised cores and inductors. If we do not have exactly what you need, we can offer a fully bespoke solution depending on the technical design parameters.
Typical applications include AC power lines (power supplies input stage), DC power lines (DC distribution lines inside multi-board systems, for example in automotive), differential data lines (digital signal noise immunity), CAN bus, and filters on power distribution cables.
