LFB310190-000

Overview

The LFB310190-000 is a solid free-hanging ferrite core designed for EMI filtering. It features an inside diameter of 19.00 mm (0.748 inches) and an outside diameter of 31.00 mm (1.220 inches). The component has a length of 13.00 mm (0.512 inches). Impedance specifications vary by source, with official documentation citing 22 Ohms at 5 MHz and third-party listings indicating 33 Ohms.

Feature Summary

• Solid construction for durable cable wrapping
• Free-hanging design allows easy installation on existing cables
• Round core geometry supports uniform magnetic flux distribution

Applications

• Cable EMI suppression
• RF noise reduction in wiring harnesses
• Signal integrity enhancement for high-frequency lines

Procurement Notes

Verify impedance ratings against specific frequency requirements, as sources cite 22 Ohms at 5 MHz and 33 Ohms generally. Confirm physical dimensions match cable outer diameters. Check RoHS compliance status if required by project specifications. Ensure the free-hanging form factor suits the assembly constraints.

Selection Notes

Select this component when large cable diameters around 19 mm require shielding. Compare impedance values from different data sources to ensure adequate attenuation at target frequencies. Consider the solid core material properties for environmental stability. Evaluate space availability for the 31 mm outer diameter footprint.
