ILBB0402ER400V

Chip Ferrite Bead Overview

The ILBB0402ER400V is a multilayer ferrite chip bead manufactured by Vishay / Dale, designed for surface-mount technology in the 0402 (1005 metric) package. It exhibits an impedance of 40 Ohms with a tolerance of 25% at a test frequency of 100 MHz. The component supports a maximum DC current of 300 mA and maintains a maximum DC resistance of 1.00 ohm. It operates within a temperature range of -40°C to +125°C and features a nickel barrier coating to prevent silver migration.

Chip Ferrite Bead Feature Summary

• Multilayer construction provides electromagnetic interference suppression in compact designs
• Nickel barrier coating enhances reliability by eliminating silver migration
• Broad operating temperature range ensures performance in rugged environments

Chip Ferrite Bead Applications

• Telecommunications equipment
• Computer systems

Chip Ferrite Bead Procurement Notes

Verify the specific manufacturer designation, as the component is listed under both Vishay and Vishay / Dale. Confirm the package dimensions match the 0402 standard and validate the impedance tolerance against project requirements. Ensure the supplier documentation explicitly references the ILBB series specifications for accurate technical compliance.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0402 footprint for EMI filtering. The 40 Ohm impedance at 100 MHz suits moderate noise suppression needs. Verify that the 300 mA current rating aligns with the circuit's operational load to prevent saturation or excessive heating during continuous use.
