Toroidal cores areused in a wide variety of applications such as power input filters, ground-fault interrupters, common-mode filters andin pulse and broadband are listed by initial permeability classes and increasing dimension of the inside toroidal cores are supplied burnished to break sharp are tested for AL values at 10 with an outside diameter of (.)

2 375'') or smaller can be supplied Parylene C coated. The Parylene coating willincrease the 'A' and 'C' dimensions and decrease the 'B' dimension a maximum of (.0015''). The ninth digit of aParylene coated toroid part number is a '1'. See the material characteristics of Parylene C in our online with an outside diameter of (.375'') or larger can be supplied with a uniform coating of thermo-set plasticcoating. This coating will increase the 'A' and 'C' dimensions and decrease the 'B' dimension a maximum of (.020'').The 9th digit of the thermo-set plastic coated toroid part number is a '2'. Thermo-set plastic coating is RoHS plastic coated parts can withstand a minimum breakdown voltage of 1000 Vrms, uniformly applied across the 'C'dimension of the ''C'' dimension may be modified to suit specific any toroidal core requirement not listed in the catalog, please contact our customer service department foravailability and of Part Numbers: Digits 1&2 = product class, 3&4 = material grade, 9th digit 1 = Parylene coating,2 = thermo-set plastic Products Corp.

4 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.

5 A turn is defined as a single pass through a hole. l/A - Core Constantle: Effective Path Length Ae.
