0431176451 – FAIR-RITE PRODUCTS CORP

The FAIR-RITE 431176451 is a hinged ferrite core designed for EMI suppression on round cables. Constructed from Fair-Rite’s proprietary #76 material, this component exhibits a nominal impedance of 380 Ohms at 100 MHz, providing effective broadband noise attenuation. The hinged design allows for post-assembly installation without disconnecting existing cabling. The core has an outer diameter of 18.34 mm, accommodating cables of a specific diameter range dependent on the inner dimensions of the core halves. The #76 material is a manganese zinc (MnZn) ferrite characterized by its high permeability and low core loss at frequencies up to several hundred MHz, making it suitable for filtering common-mode noise in various electronic applications. The hinged assembly is mechanically robust, designed for repeated opening and closing cycles without compromising the integrity of the ferrite core.
