Ring Toroids Ferrite Core-10mmX6mmX4mm
Ring cores ferrite are very useful in electrical and electronic engineering.Ring cores are used primarily for pulse and broadband transformers, baluns and chokes. In the telecommunications, they are found in interface transformers for ISDN applications and in chokes for data and signal lines.
EMC solutions with input and output chokes in switch-mode power supplies are just as dependent on ring cores as the filters of frequency converters used in electric drives for traction applications and elevators.
Lighting engineering needs them too – ring cores in drive transformers for power transistors in electronic ballasts have long been state of the art.
