Fair-Rite part number 4277353509 is a cylindrical ferrite rod constructed from Material 77. This component is designed for use in open magnetic circuit applications, specifically serving as a core for inductive components and high-energy storage designs. The solid rod format allows for winding custom coils or integrating into existing magnetic structures where temperature stability and specific permeability characteristics are required.
Verify the exact physical dimensions against your mechanical design constraints before ordering. Confirm that Material 77 aligns with your required frequency range and permeability specifications. Ensure the supplier provides the official datasheet to validate material composition and tolerance levels for your specific application requirements.
Select this component when an open-core geometry is necessary for thermal management or custom winding flexibility. Material 77 offers distinct permeability characteristics suitable for general-purpose inductive applications. Compare its performance against other Fair-Rite materials if operating frequencies or saturation levels differ significantly from standard assumptions.
This item belongs to the Fair-Rite ferrite rod product line, which provides raw magnetic material shapes for engineers to create custom transformers, inductors, and chokes. Unlike pre-formed cores, these rods allow for variable turn counts and unique form factors tailored to specific circuit topologies and space constraints.
Substitute only with other Material 77 rods of identical dimensions. Verify that alternative suppliers offer the same permeability curve and saturation flux density to maintain circuit performance integrity.
