40U1630-080

Overview

The 40U1630-080 is a solid ferrite core designed for cable suppression, manufactured by Laird-Signal Integrity Products. It provides an impedance of 47 Ohms at 5 MHz. The component features an inner diameter of 29.40 mm and an outer diameter of 41.40 mm. Its physical length measures 11.50 mm. This free-hanging core is constructed from material grade 28 and is intended for use in automotive applications, specifically for suppressing unintended signals on wires.

Feature Summary

• Solid construction for robust signal suppression
• Designed for automotive bus applications
• Free-hanging installation style

Applications

• Automotive bus signal filtering
• Cable EMI suppression
• Wire noise reduction

Procurement Notes

Verify the specific material grade and impedance characteristics against the official datasheet to ensure compatibility with target frequency ranges. Confirm that the physical dimensions match the available space in the assembly. Check for any specific automotive qualification requirements mandated by the end-use application before finalizing procurement decisions.

Selection Notes

Select this component when a high-current, large-diameter ferrite solution is required for automotive bus lines. The 47 Ohm impedance at 5 MHz targets lower frequency noise profiles typical in vehicle networks. Ensure the cable bundle fits within the 29.40 mm inner diameter without excessive strain on the core structure during installation.

Part Context

This part belongs to the cable ferrite category within Laird-Signal Integrity Products' portfolio. It serves as a passive electromagnetic interference filter for bulk cables rather than surface-mount circuit components. The design focuses on clamping around existing wiring harnesses to attenuate common-mode noise.
