Part Type Information
A ring configuration provides the ultimate utilization of the intrinsic ferrite material properties. Toroidal cores are
used in a wide variety of applications such as power input filters, ground-fault interrupters, common-mode filters and
in pulse and broadband transformers.
-Toroids are listed by initial permeability classes and increasing dimension of the inside diameter.
-All toroidal cores are supplied burnished to break sharp edges.
-Toroids are tested for AL values at 10 kHz.
-Toroids with an outside diameter of 9.5mm (.375'') or smaller can be supplied Parylene C coated. The Parylene coating will
increase the 'A' and 'C' dimensions and decrease the 'B' dimension a maximum of 0.038mm (.0015''). The ninth digit of a
Parylene coated toroid part number is a '1'. See the material characteristics of Parylene C in our online catalog.
-Toroids with an outside diameter of 9.5mm (.375'') or larger can be supplied with a uniform coating of thermo-set plastic
coating. This coating will increase the 'A' and 'C' dimensions and decrease the 'B' dimension a maximum of 0.5mm (.020'').
The 9th digit of the thermo-set plastic coated toroid part number is a '2'. Thermo-set plastic coating is RoHS compliant.
-Thermo-set plastic coated parts can withstand a minimum breakdown voltage of 1000 Vrms, uniformly applied across the 'C'
dimension of the toroid.
-The ''C'' dimension may be modified to suit specific applications.
-For any toroidal core requirement not listed in the catalog, please contact our customer service department for
availability and pricing.
-Explaination of Part Numbers: Digits 1&2 = product class, 3&4 = material grade, 9th digit 1 = Parylene coating,
2 = thermo-set plastic coating.

Preferred parts, the suggested choice for new designs,have shorter lead times and are more readily available.
The column H(Oe) gives for each bead the calculated dc bias field in oersted for 1 turn and 1 ampere direct current. The actual dc H field in
the application is this value of H times the actual NI (ampere-turn) product. For the effect of the dc bias on the impedance of the bead material,
see figures 18-23 in the application note How to choose Ferrite Components for EMI Suppression.
A ½ turn is defined as a single pass through a hole.
