28A0392-0A0

Overview

The 28A0392-0A0 is a hinged cable ferrite core manufactured by Laird-Signal Integrity Products. It provides electromagnetic interference suppression with an impedance of 170 Ohms at 100 MHz. The component features a circular design suitable for free-hanging installation on cables. Key physical dimensions include an inner diameter of 4.88 mm, an outer width and height of 13.72 mm, and a length of 30.56 mm. It operates within a temperature range of -40°C to 125°C and complies with RoHS3 standards.

Feature Summary

• Hinged snap-on design allows for easy installation around existing cables without disconnection
• Provides targeted high-frequency noise attenuation in the EMI spectrum
• Circular geometry accommodates various cable diameters within specified limits

Applications

• Suppression of common-mode noise on power supply cables
• EMI filtering for data transmission lines
• Noise reduction in automotive wiring harnesses

Procurement Notes

Verify the specific inner diameter requirement against the target cable size to ensure a secure fit. Confirm that the application environment stays within the -40°C to 125°C operating temperature range. Check for RoHS3 compliance if required by regional regulations. Ensure the impedance characteristic at 100 MHz meets the specific noise frequency profile of the circuit being filtered.

Selection Notes

Select this component when a non-invasive solution for cable noise suppression is required. The hinged mechanism distinguishes it from split-core or solid ferrites, offering convenience for retrofits. Consider the 170 Ohm impedance value relative to the noise frequencies present. Evaluate the physical space constraints against the 30.56 mm length and 13.72 mm cross-section dimensions.

Part Context

This part belongs to the 28A series of cable ferrites from Laird-Signal Integrity Products. These components are designed for broadband EMI suppression. The '28' designation typically refers to the specific ferrite material composition optimized for certain frequency ranges. This series complements other Laird filtering solutions like chip beads and inductors for comprehensive signal integrity management.

Replacement Considerations

Direct substitutes may include other hinged ferrites with similar impedance and inner diameter specifications. Verify compatibility with any alternative part number regarding mechanical fit and electrical performance characteristics.
