CUSTOM BLOCKS FERRITE

Blocks of custom ferrites are available in lengths up to 6" cubes. They are available in materials from permeability of 400ui to 10, 000ui in both Nickel Zinc (NiZn) and Manganese Zinc (MnZn) compositions.

The table below shows the material characteristics of the various types and of NiZn and MnZn ferrite blocks custom manufactured. These blocks of ferrites can be machined to various sizes and our in-house machining center can machine these blocks to any sizes with very high precision and tolerances. Please contact our sales at sales@coilws.com for quotes and more details.

Custom blocks of ferrites are frequently used in Antenna, power conversion, recording heads, filters, particle accelerators, and EMI suppressors.

The dimensional tolerances for ferrite custom blocks before machining are approximately +/- 2%. The camber tolerance is 0.11 per inch.
