LF1206E152R-10

Chip Ferrite Bead Overview

The LF1206E152R-10 is a single-line ferrite chip bead from the Laird-Signal Integrity Products series, designed for electromagnetic interference (EMI) filtering in power and signal lines. It features a 1206 (3216 metric) surface-mount package with dimensions of 3.20mm length, 1.60mm width, and a maximum height of 1.10mm. The component provides an impedance of 946 Ohms at a test frequency of 100 MHz. It supports a maximum DC current rating of 300mA and has a maximum DC resistance (DCR) of 500 milliohms. The device operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high impedance attenuation for EMI suppression in high-frequency circuits
• Monolithic construction ensures reliability in power and signal line applications
• Surface-mount design facilitates automated assembly on standard PCBs

Chip Ferrite Bead Applications

• Power supply line filtering
• Signal line noise suppression
• High-frequency circuit EMI mitigation

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value against official datasheets, as distributor listings may vary between 915 Ohms and 946 Ohms for this part number. Confirm RoHS3 compliance status and ensure the 1206 package footprint matches the target PCB layout. Check for any obsolescence notices or lifecycle changes directly from Laird-Signal Integrity Products before finalizing procurement plans.

Chip Ferrite Bead Selection Notes

Select this component when a 1206 footprint is required for filtering power or signal lines with moderate current demands up to 300mA. The 946 Ohm impedance at 100 MHz makes it suitable for suppressing noise in the upper VHF range. Ensure the application environment stays within the -40°C to +125°C operating temperature range and that the low DCR of 500 milliohms meets voltage drop requirements.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the LF series from Laird-Signal Integrity Products, which specializes in signal integrity solutions. The 1206 case size offers a balance between current handling capability and physical space constraints compared to smaller packages like 0603. It is distinct from higher-current HI series beads and lower-current HZ series variants, positioning it for general-purpose EMI filtering in consumer and industrial electronics.

Chip Ferrite Bead Replacement Considerations

Direct substitutes should be verified via Laird's part number guide. Cross-references must match the 1206 package, 300mA current rating, and ~946 Ohm impedance at 100 MHz. Generic equivalents may differ in saturation characteristics or thermal performance.
