ILB1206ER122V

Chip Ferrite Bead Overview

The ILB1206ER122V is a multilayer ferrite bead from the Vishay Dale ILB series, designed for surface-mount applications in the 1206 (3216 metric) package. It exhibits an impedance of 1.2 kOhms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 200 mA and maintains a maximum DC resistance of 400 mOhms. It operates within a temperature range of -55°C to +125°C and measures 3.2 mm in length, 1.6 mm in width, and 1.1 mm in height.

Chip Ferrite Bead Feature Summary

• Multilayer construction provides compact noise suppression in small form factors
• High impedance characteristics effectively attenuate high-frequency electromagnetic interference
• Robust thermal stability ensures reliable performance across wide industrial temperature ranges

Chip Ferrite Bead Applications

• High-speed data line filtering
• Power supply output decoupling
• Clock signal noise suppression

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value and tolerance against design requirements before ordering. Confirm that the maximum DC current rating of 200 mA aligns with the circuit's operational load to prevent saturation. Ensure the 1206 footprint matches the PCB layout constraints. Check RoHS compliance status if required by project specifications.

Chip Ferrite Bead Selection Notes

Select this component when high attenuation is needed at 100 MHz for signals carrying low DC currents. Compare the 400 mOhms DC resistance against voltage drop limits in the application. Consider the 25% tolerance for impedance variation margins. Evaluate alternative impedances if the 1.2 kOhm value exceeds necessary filtering requirements.

Chip Ferrite Bead Part Context

This part belongs to the Vishay Dale ILB-1206 series of ferrite chip beads. The series offers various impedance values within the standard 1206 SMD package. These components are engineered for general-purpose EMI suppression in portable electronics and communication devices where space is limited.

Chip Ferrite Bead Replacement Considerations

Consult official Vishay documentation for direct cross-references. Verify that any substitute part matches the 1206 package dimensions, 1.2 kOhm impedance at 100 MHz, and 200 mA current rating.
