CF1-31*19*10

Overview

The CF1-31*19*10 is a solid cylindrical ferrite core manufactured by API Delevan Inc. It features an inner diameter of 19 mm and an outer diameter of 31 mm, with a length of 10 mm. The component provides an impedance of 91 Ohms at 100 MHz. Designed for free-hanging mounting on cables, it serves as an EMI suppression device. The product complies with RoHS certification standards.

Feature Summary

• Solid cylindrical design for cable-mounted EMI suppression
• High impedance characteristic at 100 MHz
• RoHS compliant environmental certification

Applications

• Cable-mounted electromagnetic interference suppression
• Flat ribbon cable filtering applications
• General electronic equipment noise reduction

Procurement Notes

Verify the specific manufacturer designation, as API Delevan components are often listed under the Delevan brand or series identifiers. Confirm that the part number suffix matches the exact dimensional requirements (31mm OD, 19mm ID, 10mm length) and impedance rating (91 Ohms). Ensure the RoHS status aligns with project compliance requirements before finalizing procurement orders.

Selection Notes

Select this component when a solid ferrite core with a 19 mm inner diameter is required for cable wrapping. The 91 Ohm impedance at 100 MHz makes it suitable for suppressing high-frequency noise on data or power lines. Ensure the cable bundle fits within the 19 mm bore without excessive force. Consider the 31 mm outer diameter for spatial clearance in tight enclosures.

Part Context

This part belongs to the CF series of flat ribbon cable cores and cylindrical EMI suppression ferrites produced by API Delevan. The series offers various dimensions and impedance values to accommodate different cable sizes and frequency suppression needs. The CF1 variant specifically denotes a solid construction type optimized for direct cable mounting.

Replacement Considerations

The CF2-31*19*10 is a documented substitute within the same family, sharing identical physical dimensions but potentially differing in material composition or specific impedance characteristics. Verify functional equivalence before substitution.
