Toroidal cores : 
Toroidal cores provide high performance when wound and used as cores for transformers, inductors, or chokes .

 Outline :
The key to supp-ressing radiated noise emi-ssions generated by electr- onic equipment and systems is successful application of effective common-mode countermeasures at data lines. It could be used with series data lines, the data line is wrapped around the filter cores.Located between the CPU and terminal, they Dramatically reduce electro-magnetic noise .

 Features : 
Minimal effect on transmission waveforms. Provide low cost noise coun-termeasures right at the data lines.Can be added as First-Aid,On-The Spot counterme-asures when equipment or devices fail.Application: Com-puters, peripherals and term-inals data, Terminal equipm-ent.NC machines.Measuring equipment, equipment using sensors. OA equipment,Plain paper copiers. Improvement of noise immunity for TVs, FM/AM Tuners, VTRs/VCRs.Harness noise countermeas-ures for automobiles.ISDN terminal equipment.

 Application : 
LAN matching and isolation transformers.LAN common mode chokes.Power supply common chokes. Inductors. Current sensing transformers. DC-DC converters. Telecommunications. transformers. Linghting Ballasts. EMI filters.
