LFB250150-000

Overview

The LFB250150-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products, designed for electromagnetic interference (EMI) suppression on cables. It features an inner diameter of 15.00 mm and an outer diameter of 25.00 mm with a length of 13.00 mm. The component provides an impedance of 26 Ohms at 5 MHz for a single turn configuration. This passive filter element is intended to be clamped around conductors to attenuate high-frequency noise.

Feature Summary

• Solid construction allows for easy installation onto existing cable assemblies without cutting wires.
• Provides effective common-mode noise attenuation for power and signal lines.
• Free-hanging design facilitates integration into various enclosure or chassis mounting scenarios.

Applications

• Suppression of EMI on AC/DC power cords
• Noise filtering on data communication cables
• Attenuation of radio frequency interference in industrial equipment

Procurement Notes

Verify the specific impedance requirement against the application's noise spectrum, as this component is rated at 26 Ohms at 5 MHz. Confirm that the cable diameter falls within the 15.00 mm inner diameter specification to ensure proper fit. Check for RoHS compliance status if required by your manufacturing standards, as older Laird inventory may vary. Ensure the physical dimensions match your available space constraints.

Selection Notes

Select this part when a non-invasive, snap-on solution is preferred over soldered beads. The 15 mm bore size accommodates thicker cables typical of mains power or heavy-duty industrial connections. Consider the 26 Ohm impedance value relative to the target noise frequencies; higher frequencies may require different material compositions or multi-turn configurations to achieve sufficient attenuation levels for your specific EMC requirements.

Part Context

This ferrite core belongs to Laird-Signal Integrity Products' range of passive EMI suppression components. Unlike surface-mount or through-hole beads, these cores are installed post-assembly. They complement other filtering solutions by providing targeted noise reduction on outgoing or incoming cables, helping systems meet regulatory emissions standards without altering internal circuit board layouts.

Replacement Considerations

Direct substitutes include other solid ferrite cores with similar 15 mm inner diameters and comparable impedance characteristics at relevant frequencies. Verify that any replacement maintains the same physical envelope and material properties to ensure equivalent noise suppression performance.

FAQ

What is the impedance of the LFB250150-000 at 5 MHz?

The impedance is 26 Ohms when one turn of cable passes through the core.

Can multiple turns of cable be used with this core?

Yes, wrapping the cable multiple times increases the effective impedance proportionally, though the base rating is specified for a single turn.

What is the maximum cable diameter this core can accommodate?

The inner diameter is 15.00 mm, so it fits cables with a diameter up to this limit.
