Its physical dimensions are specified as 0.138 inches in diameter by 0.350 inches in length, corresponding to 3.51mm x 8.89mm. The device is currently active and compliant with RoHS3 standards.

Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics at specific radio frequencies.
• Utilizes axial lead construction suitable for through-hole insertion into printed circuit boards.
• Engineered for reliable performance across extended industrial temperature environments.

Applications

• Suppression of conducted noise on signal lines
• Filtering high-frequency interference in power supply inputs
• EMI reduction in communication equipment cabling

Procurement Notes

Verify the exact impedance specification against the latest manufacturer datasheet, as sources indicate variations such as 98 Ohms at 100 MHz or 142 Ohms at 250 MHz. Confirm RoHS3 compliance status and ensure the axial package dimensions match your board layout requirements before finalizing orders.

Selection Notes

Select this component when axial mounting is required for effective high-frequency noise attenuation. Ensure the operating environment stays within the specified -55°C to +125°C range. Consider the physical size constraints relative to available PCB space and verify that the impedance profile matches the target noise frequency spectrum.

Part Context

This ferrite bead belongs to Fair-Rite's line of passive EMI/RFI suppressors. It utilizes specialized ferrite materials to absorb high-frequency energy, converting it into negligible heat.
