HFA259131-0A2

Overview

The HFA259131-0A2 is a hinged, free-hanging ferrite cable core manufactured by Laird-Signal Integrity Products. It provides effective electromagnetic interference (EMI) suppression for cables. The component features an inside diameter of 13 mm and exhibits an impedance of 250 ohms at 300 MHz. It operates within a temperature range of -40°C to 125°C.

Feature Summary

• Hinged snap-on design allows for easy installation on existing cables without disconnection.
• Provides effective EMI suppression for high-frequency noise reduction.
• Free-hanging construction suitable for various cable diameters up to the specified limit.

Applications

• Suppression of electromagnetic interference in data communication cables
• Noise filtering for power supply lines in electronic equipment
• EMI mitigation in automotive wiring harnesses

Procurement Notes

Verify the specific impedance requirements against application frequency spectra. Confirm that the cable diameter fits within the 13 mm internal dimension. Check for RoHS compliance status if required by project specifications. Ensure the hinged mechanism integrity is maintained during handling and installation.

Selection Notes

Select this component when a non-invasive solution for cable noise suppression is required. The hinged design facilitates retrofitting onto assembled cables. Consider the 250 ohm impedance at 300 MHz to ensure compatibility with the target noise frequencies. Verify thermal stability requirements against the -40°C to 125°C operating range.

Part Context

This part belongs to the HFA series of cable ferrites from Laird-Signal Integrity Products. These cores are designed for general-purpose EMI suppression. The hinged variant offers convenience over solid cores for field applications. It complements other Laird signal integrity products focused on noise control.

Replacement Considerations

Solid core alternatives like the 28B0157-100 require cable disconnection. Verify impedance curves match the original design intent. Ensure physical dimensions accommodate the target cable bundle size.
