ILHB1206ER501V

Chip Ferrite Bead Overview

The ILHB1206ER501V is a multilayer ferrite bead from the Vishay Dale ILHB series, designed for surface mount applications in the 1206 (3216 metric) package. It provides an impedance of 500 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 2.5 A and features a maximum DC resistance of 60 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 up to 1.30 mm in height.

Chip Ferrite Bead Feature Summary

• Magnetically self-shielded construction minimizes electromagnetic interference coupling between adjacent circuits.
• Multilayer chip technology enables high reliability and suitability for automated surface mount assembly processes.
• High current handling capability allows effective noise suppression in power supply lines without significant saturation.

Chip Ferrite Bead Applications

• Power supply output filtering for digital logic circuits
• Noise suppression on data bus lines in high-speed interfaces
• EMI reduction in automotive electronic control units

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'ER' against the manufacturer's latest datasheet to confirm impedance tolerance and material composition. Ensure the ordering quantity aligns with standard reel sizes, typically 3000 units per reel, or cut tape availability if partial quantities are required. Confirm RoHS compliance status for the specific production batch prior to integration into regulated assemblies.

Chip Ferrite Bead Selection Notes

Select this component when a 500 Ohm impedance at 100 MHz is required for EMI suppression in space-constrained designs. The 1206 footprint offers a balance between current capacity and board area. Compare the 60 mOhm DCR against circuit voltage drop requirements. Consider the self-shielded feature if components are placed in close proximity to sensitive signal traces.

Chip Ferrite Bead Part Context

This part belongs to the ILHB series of high-current multilayer ferrite beads manufactured by Vishay Dale. The series is characterized by its ability to handle currents up to 6 A in larger packages while maintaining low DC resistance. The ILHB1206ER501V specifically targets applications requiring moderate current handling with significant high-frequency attenuation in a standard SMD form factor.

Chip Ferrite Bead Replacement Considerations

Würth Elektronik part number 742792116 is identified as a parameter-equivalent substitute. Verify that the alternative component matches the 500 Ohm impedance at 100 MHz, 2.5 A current rating, and 1206 package dimensions before implementation.
