Ferrite RM (square) Cores

The design of Yuxiang RM cores (square cores) maximizes magnetic performance while minimizing PC board space--at least a 40% savings in mounting area! Special advantages of Yuxiang 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:

  1. Electromagnetic Features: self-shielding, simple tuning adjustments, temperature stability, and low
  2. 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.
