Ferrite RM (square) Cores
The design of RM cores (square cores) maximizes magnetic performance while minimizing PC board space–at least a 40% savings in mounting area! Special advantages of RM Core assemblies, like wide core selection such as RM5 core, MnZn Core RM12, RM6 core, RM8 core, RM10 core, RM12 core, RM14 core, RM4, RM5, RM6, RM8, RM10, RM14, RM14 cores, RM12 cores, RM10 cores, RM8 cores, RM4 cores, RM5 cores, RM6 cores, etc; choice of linear or flat temperature characteristics; and consistency and uniformity. Yuxiang RM cores are offered in a wide variety of materials to support various applications. Ferrite RM core is available either gapped or ungapped.
Advantages of ferrite RM core
In addition to all of the magnetic and mechanical advantages of pot cores, RM cores offer the following advantages:
Electromagnetic Features: self-shielding, simple tuning adjustments, temperature stability, and low losses; Mechanical Features: compactness, bobbin winding, ease of assembly, PCB mounting, and automated assembly possible.
Application of RM core
RM core applications: filters, inductors and transformers for telecommunication and other electronic equipment. RM cores are for high effective packing density. Ferrite Power Core RM4 RM5 RM6 RM7 RM8 RM10 RM12 RM14 RM14R
Because of their magnetic characteristics, ferrites are used in the construction of antennas, the manufacture of coils and transformer, and as suppressors within devices and computers. In principle they are simply magnets. Despite their brittleness due to their ceramic material of iron oxide and other metal oxides, they are still used universally in all areas of electrotechnology. The background to this is that any movement of charge within a conductor – for instance currents flowing in wires, or computer power supplies – creates electromagnetic and magnetostatic effects on the immediate environment. The resulting stray magnetic fields can cause interference in adjoining electronic circuits. Ferrites have the capability to compensate these effects in a positive sense.
