HFA100035-0A2

Overview

The HFA100035-0A2 is a split ferrite core manufactured by Laird-Signal Integrity Products, designed for EMI suppression on cables. It features a snap-on hinged design for easy installation without disconnecting wires. The component has an inner diameter of 3.50mm (0.138 inches) and outer dimensions of 11.50mm x 11.50mm (0.453" W x 0.512" H). It provides an impedance of 172 Ohms at 300MHz using HF material. The total length is 25.2mm. It complies with RoHS standards.

Feature Summary

• Snap-on hinged design allows installation on existing cables without disconnection
• Utilizes high-frequency (HF) ferrite material for effective noise suppression
• Free-hanging configuration suitable for various cable diameters

Applications

• EMI/RFI noise reduction in electronic equipment cabling
• Signal integrity enhancement for high-speed data lines
• Compliance support for electromagnetic interference regulations

Procurement Notes

Verify the specific impedance value and frequency rating against your application requirements, as datasheets may list variations such as 172 Ohms at 300MHz or 192 Ohms at 500MHz depending on the exact revision. Confirm the RoHS compliance status and ensure the split-core mechanism is compatible with your cable assembly process. Check for any specific packaging quantities required by your supply chain.

Selection Notes

Select this component when a non-intrusive installation method is required for cable shielding. The 3.50mm inner diameter accommodates standard cable sizes within that range. Ensure the operating environment does not exceed the thermal limits of the HF material. Compare impedance characteristics at your target noise frequency to confirm effectiveness over solid cores if space permits.

Part Context

This part belongs to the HFA series of split ferrite cores from Laird-Signal Integrity Products. These components are engineered for signal integrity applications where rapid deployment on terminated cables is necessary. The series offers various impedance ratings and physical sizes to match different cable gauges and frequency profiles.

Replacement Considerations

Direct substitutes must match the 3.50mm inner diameter and snap-on mechanical design. Verify that alternative parts provide equivalent impedance at 300MHz or higher frequencies. Ensure the replacement also meets RoHS requirements if applicable to your manufacturing standards.
