MAGNETICS® Ferrite RM (square) Cores Ferrite RM (square) Cores

The design of MAGNETICS® RM cores (square cores) maximizes magnetic performance while minimizing PC board space--at least a 40% savings in mounting area!  In addition to all of the magnetic and mechanical advantages of pot cores, RM cores offer the following advantages:

Electromagnetic Features Mechanical Features
  • self-shielding
  • simple tuning adjustments
  • temperature stability
  • low losses
  • compactness
  • bobbin winding
  • ease of assembly
  • PCB mounting
  • automated assembly possible
Special Advantages of MAGNETICS RM Core Assemblies
  • wide core selection
  • choice of linear or flat temperature characteristics
  • consistency and uniformity
  • MAGNETICS RM cores are offered in a wide variety of materials to support various applications.  Cores are available either gapped or ungapped.
