40U1261-080

Overview

The 40U1261-080 is a solid ferrite core manufactured by Laird-Signal Integrity Products, designed for automotive applications. It features a cylindrical shape with an inner diameter of 2.00mm and an outer diameter of 4.00mm. The component measures 10.00mm in length and provides an impedance of 121 Ohms at 100MHz. Constructed from material grade 28, it is suitable for free-hanging installation on cables to suppress electromagnetic interference.

Feature Summary

• Solid construction for durable cable mounting
• Optimized for automotive bus line filtering
• Cylindrical geometry for uniform magnetic flux

Applications

• Automotive bus line EMI suppression
• Cable shielding for electronic modules
• Signal integrity enhancement in vehicle wiring

Procurement Notes

Verify the specific material grade and impedance tolerance against the official datasheet before integration. Confirm that the physical dimensions match the cable diameter requirements of the target assembly. Ensure compliance with relevant automotive standards if applicable to the end-use environment.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable installations. The fixed inner diameter dictates the maximum cable size it can accommodate. Consider the operating frequency range where the 121 Ohm impedance provides effective noise attenuation.

Part Context

This part belongs to the cable ferrite category within Laird's signal integrity portfolio. It serves as a passive component to mitigate high-frequency noise on conductors without requiring active circuitry. Its design focuses on mechanical stability and consistent electromagnetic performance in harsh environments.

Replacement Considerations

No public substitute part numbers are confirmed for this specific model.
