CF1-4.6*1.85*6

Overview

The CF1-4.6*1.85*6 is a solid cable ferrite core manufactured by API Delevan Inc., designed for electromagnetic interference suppression in electronic circuits. This component features an integrated combining form and is specified for use with round cables. It provides an impedance of 89 Ohms at a frequency of 100 MHz, ensuring effective noise attenuation across the targeted bandwidth. The physical dimensions include an outside diameter of 4.6 mm, an inside diameter of 1.85 mm, and an overall length of 6 mm. The unit utilizes a free-hanging mounting type, allowing for flexible installation on wires without requiring additional hardware or PCB footprint constraints.

Feature Summary

• Solid construction design for consistent magnetic properties
• Integrated form factor suitable for direct wire application
• Free-hanging mounting capability for versatile integration

Applications

• Suppression of electromagnetic interference in round cable assemblies
• Noise filtering in high-frequency signal lines operating around 100 MHz
• EMI reduction in compact electronic device wiring harnesses

Procurement Notes

Verify the manufacturer designation as API Delevan Inc. when sourcing this component. Confirm that the part number corresponds to the specific impedance value of 89 Ohms at 100 MHz. Ensure the physical dimensions match the required clearance for your assembly, specifically the 4.6 mm outer diameter and 1.85 mm inner diameter. Check for any specific handling requirements associated with ceramic or ferrite materials during installation.

Selection Notes

Select this component when a solid, non-split ferrite core is required for round cables. The 1.85 mm inner diameter dictates the maximum cable size it can accommodate. Choose this part if the application demands an impedance of approximately 89 Ohms at 100 MHz. Consider the 6 mm length and 4.6 mm diameter to ensure adequate space within the enclosure for heat dissipation and mechanical clearance.

Part Context

This ferrite core belongs to the CF1 series from API Delevan, which focuses on passive components for EMI suppression. The model number encodes key physical attributes: 4.6 likely refers to the outer diameter in millimeters, 1.85 to the inner diameter, and 6 to the length. These cores are commonly used in consumer electronics and industrial equipment to mitigate conducted emissions without altering the circuit board layout.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. When seeking alternatives, ensure the replacement matches the 89 Ohm impedance at 100 MHz, maintains the 1.85 mm inner diameter for cable fit, and adheres to the 4.6 mm outer diameter constraint.
