28B0625-100

Overview

The Laird-Signal Integrity Products 28B0625-100 is a solid, free-hanging cylindrical ferrite core designed for EMI suppression on round cables and wiring harnesses. It belongs to the 28B series and utilizes material grade 28. The component provides an impedance of 280 ohms at 100 MHz. Its physical dimensions include an inner diameter of 7.87 mm (0.310 inches), an outer diameter of 15.88 mm (0.625 inches), and a length of 28.58 mm (1.125 inches).

Feature Summary

• Solid construction for secure mounting on cables without splitting.
• High impedance performance at 100 MHz for effective noise attenuation.
• Cylindrical geometry compatible with standard round wire harnesses.

Applications

• Suppression of electromagnetic interference in round cable assemblies.

Procurement Notes

Verify the specific impedance requirement of 280 ohms at 100 MHz against the application's noise spectrum. Confirm that the 7.87 mm inner diameter accommodates the target cable bundle size. Ensure the solid form factor aligns with assembly constraints where split cores are not feasible. Check RoHS3 compliance status if required by the end product regulations.

Selection Notes

Select this component when high impedance is needed for broadband noise reduction on round cables. The solid design offers mechanical stability compared to split cores. Consider the 28B series material properties for frequency response characteristics. Evaluate the physical length and diameter to ensure fit within the available space around the cable.
