The core material is designated as type 28, providing an impedance of 286 Ohms at 100 MHz. Physical dimensions include an internal length of 64.5 mm, an external length of 91.9 mm, and an external width of 46.5 mm. The internal height is 1.5 mm, while the external height measures 16.6 mm. This component includes adhesive backing for secure mounting.

Feature Summary

• Hinged snap-on construction allows for quick attachment to flat ribbon cables without disconnection.
• Integrated adhesive backing ensures stable positioning on target surfaces.
• Type 28 ferrite material provides specific high-frequency noise suppression characteristics.

Applications

• Noise suppression on flat ribbon cables in electronic assemblies
• EMI mitigation in data transmission lines
• Shielding of internal cable harnesses in computing hardware

Procurement Notes

Verify the specific adhesive type and surface preparation requirements before application to ensure long-term bond integrity. Confirm that the flat cable thickness falls within the 1.5 mm internal height specification to guarantee proper closure of the hinged mechanism. Check RoHS compliance documentation if required for your specific manufacturing standards.

Selection Notes

Select this model when a snap-on ferrite with integrated mounting is required for flat cables. Ensure the operating frequency aligns with the 286 Ohm impedance rating at 100 MHz. Compare physical envelope constraints against the 91.9 mm external length and 46.5 mm width to verify fitment within the equipment chassis or cable routing path.
