FFAT-54

Overview

The Delevan FFAT-54 is a tubular flexible ferrite absorber designed for EMI/RFI suppression. It features an inner diameter of 4.00 mm (0.157 inches) and an outer diameter of 5.00 mm (0.197 inches). The component provides an impedance of 138 Ohms at 100 MHz. Each unit has a length of 1.00 meter (3.281 feet). It is classified as a free-hanging cable ferrite core intended for direct installation on wires.

Feature Summary

• Flexible tubular construction allows easy installation onto existing cables without disconnection
• Provides broadband electromagnetic interference attenuation through magnetic absorption
• Free-hanging design enables secure mounting on various wire gauges within specified dimensions

Applications

• Suppression of common-mode noise on data and power cables
• EMI reduction in telecommunications equipment wiring
• Noise filtering in industrial control system interconnects

Procurement Notes

Verify the specific manufacturer part number against official API Delevan documentation to ensure compatibility with required impedance and dimensional specifications. Confirm RoHS3 compliance status if restricted substance regulations apply to your assembly process. Cross-reference distributor listings with original datasheets to validate technical parameters such as impedance frequency characteristics before procurement.

Selection Notes

Select this component when flexible ferrite tubing is required for retrofitting or space-constrained cable management applications. Ensure the target cable diameter falls within the 4.00 mm inner diameter specification. Consider the 138 Ohm impedance at 100 MHz for suitability against the specific noise frequencies present in the application environment compared to alternative series values.

Part Context

This component belongs to the FFAT series of flexible ferrite absorbent tubing manufactured by API Delevan. The series is engineered for high-performance EMI suppression in compact electronic assemblies. The FFAT-54 variant specifically targets cables requiring a 4 mm bore size, offering a balance between mechanical flexibility and magnetic permeability for effective noise dissipation.

Replacement Considerations

Consult official API Delevan substitution guides for equivalent impedance profiles. Verify that any alternative tubular ferrite maintains the 4.00 mm inner diameter and compatible outer dimensions for physical fitment. Ensure material composition matches environmental requirements.
