Project Description

ferrite p cores

Ferrite P cores are the earliest design for telecom filter inductors. As with RM cores there is a complete, standardized range (IEC133). The cores are available in a range of AL-value from many supplies. The core surrounds the winding almost completely so magnetic shielding is outstanding. The slots in the core are rather narrow which complicates assembly and mounting. A complete range of accessories is available, but most are not optimized for easy automatic handling.

Summary:

  • Excellent magnetic shielding
  • Complete range of sizes and material grades
  • Not easy to assemble and mount
  • Difficult to get leads out
  • Mains insulation difficult
