The Ferroxcube BD5.1/2/10-4S2 is a single-hole ferrite bead designed for cable noise suppression. It features a cylindrical geometry with specific dimensional tolerances: an outer diameter of 5.1 ± 0.3 mm, an inner diameter of 2 + 0.2 mm, and a length of 10 ± 0.3 mm. The component provides an impedance of 100 Ohms at 100 MHz and is engineered for cables with a diameter of 2 mm.
Verify the complete part number including the suffix to ensure correct material grade and impedance characteristics. Confirm that the cable diameter matches the specified inner diameter tolerance to guarantee proper fit and performance. Check for any specific environmental ratings if operating conditions exceed standard limits.
Select this component when a low-profile, single-hole ferrite solution is required for cables up to 2 mm in diameter. Ensure the target frequency range aligns with the 100 Ohm impedance specification at 100 MHz. Consider mechanical constraints regarding the outer diameter and length during PCB or chassis layout.
This part belongs to the Ferroxcube BD series of ferrite beads, which are standardized components for EMI suppression. The series offers various dimensions and impedance levels to accommodate different cable sizes and frequency requirements across industrial and consumer electronics applications.
Direct substitutes may include other single-hole ferrite beads with matching inner diameter (approx. 2 mm) and similar impedance profiles at 100 MHz. Verify physical dimensions and mounting compatibility before substitution.
