CA25B1642

Overview

The CA25B1642 is a hinged ferrite clamp-on core manufactured by Leader Tech Inc. It features a split design for easy installation around existing cables without disconnection. The component is constructed from high-permeability ferrite material to suppress electromagnetic interference (EMI) and radio frequency interference (RFI). It has an inner diameter of 7.60 mm, accommodating specific cable sizes. The unit provides an impedance characteristic of 290 Ohms at its rated frequency, serving as a passive noise suppression device for signal and power lines.

Feature Summary

• Hinged split-core design allows for rapid installation on terminated cables
• High permeability ferrite composition for effective EMI/RFI attenuation
• Compact cylindrical geometry suitable for constrained wiring environments

Applications

• Suppression of common-mode noise on data communication cables
• Noise reduction on power supply lines in electronic equipment
• Interference mitigation in automotive wiring harnesses

Procurement Notes

Verify the specific impedance value and frequency rating against the official Leader Tech datasheet before integration. Confirm that the 7.60 mm inner diameter matches the target cable outer diameter to ensure proper magnetic coupling. Check RoHS compliance status if required by your manufacturing standards. Ensure the hinged mechanism remains secure during operation to maintain shielding effectiveness.

Selection Notes

Select this component when retrofitting noise suppression onto existing cabling is necessary. The hinged form factor eliminates the need to disconnect wires during assembly. Compare the 290 Ohm impedance specification with the noise spectrum of the application to ensure adequate attenuation. Consider the physical size constraints relative to the cable bundle diameter.

Part Context

This part belongs to the Leader Tech ferrite clamp-on core family, designed for EMI suppression. It complements other snap-on and slide-on ferrites in the manufacturer's portfolio. The product line focuses on providing flexible shielding solutions for various cable diameters and interference frequencies across industrial and consumer electronics sectors.

Replacement Considerations

Consult the official Leader Tech substitution guide for direct equivalents. Verify that any alternative part matches the 7.60 mm inner diameter and 290 Ohm impedance characteristics. Ensure the replacement also features a hinged design if field installation is required.
