EMI-suppression tubular cores CST

Ferroxcube  CST coresFerroxcube CST cores (ferrite tubes) are Ferroxcube CST cores (ferrite tubes) are suitable for EMI-suppression and device protection from high-frequency interference, appearing in the equipment over AC power line or due to devices closely arranged to each other.

Geomatrical dimensions and characteristics

When choosing CST cores one of the main features is inside ferrite tube diameter, which must differ from wire diameter and show maximally possible impedance in required frequence band (possible band of general high-frequency interference).

Ferrite cores CST, particularly on the base of Mn-Zn materials with low electrical resistivity are recommended to be to attached to interface cables and power cables.

The full list of Ferroxcube CST cores is represented below.
