These components were not specifically manufactured for an individual application, so be sure to check the dimensional descriptions carefully before purchasing. Returns or requests for refunds due to fit issues or similar problems will not be honored. If you require additional technical information, design, or application engineering consultation, feel free to contact the seller. Lot of six Ferronics Inc. Toroids, number 11-761-K, made of Nickel Zinc Ferrite ceramic beads, spacers, bushings, and washers are up for bidding. These components have high hardness, stiffness, and corrosion resistance, making them suitable for various electrical, mechanical, and thermal applications including use as standoffs for firing parts in a kiln and jewelry-making. They can also be used as wireless heating elements by absorbing microwave and converting it to infrared radiation, or red heat. Specifications for these components include an outside diameter of approximately 0.500" (12.70mm), inside diameter of approximately 0.281" (7.14mm), and thickness of approximately 0.375" or 1/2" (9.5mm). The effective dimensions are Ae(cm2) - 0.301 and Ie(cm) - 2.95. The specific heat for these components is 0.25 cal/g/В°C or 0.9 J/g*K. Additionally, these components have an expansion coefficient or CTE of 8-10 x 10-6/В°C, a volume resistivity at 20В°C of 107 Ohm*cm, and a modulus of elasticity of 18 x 106 p.s.i. or 145 GPa. The initial permeability for these components is (Вµi) 125 and the loss factor (tan?/Вµi) @10 MHz is 150 x 10-6. The saturation flux density is (Bs) 320 mTesla or 3200 Gauss @ Hmax.:2000 A/m, 25 Oersted. The remnance is (Br) 160 mTesla or 1600 Gauss and the coersivity is (Hc) 119 A/m or 1.5 Oersted. The temperature coefficient of Вµi (?) -40В°C to +80В°C (T.C.) is 0.1, and the Curie temperature is 350. Shop using cart for multiple items to get a combined shipping discount.
