Toroids
Description
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 9.5 mm (0.375") 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 0.038 mm (0.0015"). The ninth digit of a
Parylene coated toroid part number is a "1". See reference tables for the material characteristics of Parylene C. Parylene C
coating is RoHS compliant.
• Toroids with an outside diameter of 9.5 mm (0.375") 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 0.5 mm (0.020").
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 €œC€ 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.
• Explanation of Part Numbers: Digits 1&2 = product class, 3&4 = material grade, 9th digit 1 = Parylene coating, 2 = thermo-set
