FFAT-117

Overview

The FFAT-117 is a tubular free-hanging ferrite core manufactured by API Delevan. It features an inner diameter of 7.00 mm (0.276 inches) and an outer diameter of 11.00 mm (0.430 inches). The component provides an impedance of 137 Ohms at a test frequency of 100 MHz. Each unit has a length of 1.00 meter (3.281 feet). This design supports direct cable insertion without additional mounting hardware.

Feature Summary

• Tubular geometry designed for free-hanging installation on cables
• Provides specific electromagnetic interference suppression characteristics at high frequencies
• Standardized dimensions accommodate common cable sizes

Applications

• Cable noise suppression in electronic assemblies
• Electromagnetic interference filtering for signal lines
• High-power motor control cabinet wiring protection

Procurement Notes

Verify the manufacturer designation, as API Delevan products are often associated with the Delevan brand name. Confirm that the required impedance value of 137 Ohms at 100 MHz matches your circuit requirements. Ensure the physical dimensions, specifically the 7.00 mm inner diameter, fit the target cable bundle securely. Check for any specific packaging or length variations if exact meter counts are critical.

Selection Notes

Select this component when a tubular ferrite core is required for passive EMI suppression. The 137 Ohm impedance rating is suitable for high-frequency noise attenuation. Consider the 7.00 mm inner diameter to ensure compatibility with the cable thickness. The 1-meter length allows for cutting to size or covering multiple connection points along a wire run.

Part Context

This part belongs to the FFAT series of tubular ferrite cores from API Delevan. These components are engineered for general-purpose electromagnetic interference suppression. The series offers various impedance ratings and dimensional configurations to suit different cable diameters and frequency requirements.

Replacement Considerations

Consult official substitution lists for equivalent ferrite cores with matching impedance and dimensional specifications. Verify that alternative parts maintain the same 137 Ohm performance at 100 MHz and compatible inner diameter constraints.
