CF2-31*19*10

Overview

The CF2-31*19*10 is a solid free-hanging ferrite core manufactured by API Delevan. It features an impedance of 83 Ohms at 100 MHz. The component has an inner diameter of 19.00 mm, an outer diameter of 31.00 mm, and a length of 10.00 mm. Designed for cable and wiring applications, it serves as an EMI suppression filter.

Feature Summary

• Solid construction for stable electromagnetic interference suppression
• Free-hanging mounting style suitable for cables and wiring
• Specific impedance rating effective at high frequencies

Applications

• EMI suppression on cables and wiring
• Common mode noise filtering in electronic assemblies
• Signal integrity enhancement in data transmission lines

Procurement Notes

Verify the exact part number syntax, specifically the asterisk separators, against official API Delevan documentation to ensure correct identification. Confirm that the required impedance value of 83 Ohms at 100 MHz matches the specific design requirements for the target application before procurement.

Selection Notes

Select this component when a through-hole or free-hanging ferrite solution is required for large diameter cables. Ensure the cable diameter fits within the 19.00 mm inner dimension. Consider the physical dimensions of 31.00 mm outer diameter and 10.00 mm length for spatial constraints in the final assembly.

Part Context

This ferrite core belongs to the CF series from API Delevan, which specializes in passive components for signal integrity. It is distinct from molded inductors like the 4307R series, serving primarily as a clamp-on filter rather than a circuit board mounted reactive element.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative ferrite cores based on matching impedance curves and physical dimensions.
