LFB290190-000

Overview

The LFB290190-000 is a solid round ferrite cable core manufactured by Laird-Signal Integrity Products. It features an inner diameter of 19.05 mm and an outer diameter of 28.98 mm, with an external length of 15.21 mm. The component provides an impedance of 34 ohms at 500 MHz and 22 ohms at 5 MHz. It operates within a temperature range of -40°C to +125°C and utilizes LF material composition.

Feature Summary

• Solid round construction for direct cable sliding
• High impedance performance in the MHz frequency range
• Wide operating temperature tolerance

Applications

• EMI suppression on power cables
• Signal line noise filtering
• Cable assembly interference reduction

Procurement Notes

Verify the specific impedance requirement against application needs, as values vary by frequency (e.g., 34 ohms at 500 MHz versus 22 ohms at 5 MHz). Confirm that the 19.05 mm inner diameter accommodates the target cable bundle size. Ensure the operating environment stays within the specified -40°C to +125°C range for reliable performance.

Selection Notes

Select this part when a large bore ferrite core is required for thick cables or multi-conductor bundles. The solid design allows for easy installation without disassembly. Consider the physical dimensions carefully to ensure fitment within the available space. The LF material offers stable magnetic properties across the specified temperature range.
