This auction features a lot of twelve Ferronics Inc. Toroids, specifically the 21-714-V Nickel Zinc Ferrite ceramic spacer/bead/bushing/tube. These toroids are in mint condition and are considered NOS (new old stock). The materials used in the toroids are Nickel Oxide, Zinc Oxide, and Iron Oxide. This mix of materials creates a material with high hardness, rigidness, and corrosion resistance to chemicals at high temperatures and during use. There is a broad range of electrical, mechanical, and thermal applications for these toroids. The specifications for these components are as follows: an outside diameter of approximately 0.316 inches (8.03mm), inside diameter of approximately 0.120 inches (3.05 mm), and a thickness of approximately 0.187 inches (4.75 mm). With an effective dimension of Ae(cm2) - 0.124 and IE(cm) - .95, Specific Heat of 0.25 cal/g/-C and 0.9 J/g*K, Expansion Coefficient or CTE is 8-10 x 10-6/-C, Volume Resistivity at 20-C: 25 Ohm-cm, Modulus of Elasticity at 18 x 106 p.s.i. or 145 GPa, Initial Permeability of -I16,250, Loss Factor of (tan?/-i) @0.1 MHz - 7, Hysteresis Factor of (h-2) - -, Saturation Flux Density (Bs) of 370 mTesla, 3700 Gauss at H max.:1000 A/m, 12.6 Oersted, Remanence (Br) at 150 mTesla, 1500 Gauss, Coersivity (Hc) at 2.3 A/m, 0.03 Oersted, Temperature Coefficient of -i (?) at -40-C to +80-C (T.C.) of 0.8, and Curie Temperature of These Ferronics Toroids are a versatile component and can be used as stand-offs during firing parts in a kiln, jewelry, and wireless heating elements in microwaves. The Ferrites use fibrous thermal insulation to absorb the microwave and convert it into infrared radiation, providing red heat.
