Toroids (5975000201) Part Number: 5975000201 75 TOROID Explanation of Part Numbers: Digits 1 & 2 = Product Class Digits 3 & 4 = Material Grade 9th digit 1 = Parylene Coating,2 = Thermo- Set Plastic Coating 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. All toroidal cores are supplied burnished to break sharp edges. Coating Options: 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.
