59x Toroid Rings

Fair-Rite 59x Toroid Rings are designed with a ring configuration that provides the ultimate utilization of the intrinsic ferrite material properties. These toroid cores are built using thermo-set plastic-coated parts that can withstand a minimum breakdown voltage of 1000V_rms. Fair-Rite 59x Toroid Cores are supplied burnished to break sharp edges. These cores are ideal for power input filters, ground-fault interrupters, common-mode filters, and pulse and broadband transformers.
