28R1775-000

Overview

The Laird-Signal Integrity Products 28R1775-000 is a solid ferrite cable core designed for broadband electromagnetic interference (EMI) filtering. It features a split, snap-on plastic case construction that allows for easy installation on cables without disconnection. The component utilizes material grade 28 to provide an impedance of 260 Ohms at 100 MHz. Its physical dimensions include an internal slot measuring 34.42 mm in width by 1.52 mm in height, accommodating flat ribbon cables. The unit is classified as free-hanging and operates within a temperature range up to +125°C.

Feature Summary

• Snap-on split design enables rapid installation on existing cabling without circuit interruption
• Solid ferrite construction provides effective broadband EMI suppression
• Lightweight plastic housing protects the core while facilitating handling

Applications

• Suppression of unintended signals on flat ribbon cables
• Filtering emissions from wires in electronic assemblies
• Common mode noise reduction in signal integrity applications

Procurement Notes

Verify the specific impedance value and frequency rating against the official datasheet before integration. Confirm that the internal slot dimensions match the target cable geometry to ensure proper fit. Check for RoHS compliance status and lead times with authorized distributors. Ensure the part number suffix corresponds to the required packaging format.

Selection Notes

Select this component when broadband filtering is required for flat ribbon cables that cannot be easily disconnected during assembly. The solid split-core design offers a cost-effective alternative to clamping over connectors. Consider the 260 Ohm impedance profile for high-frequency noise attenuation. Evaluate the physical size constraints to ensure the 34.42 mm length fits within the available space.
