LF1206A302R-10

Chip Ferrite Bead Overview

The LF1206A302R-10 is a single-line ferrite bead manufactured by Laird-Signal Integrity Products, designed for EMI filtering in power and signal lines. It features an impedance of 760 Ohms at 100 MHz and supports a maximum current rating of 100mA. The component has a maximum DC resistance (DCR) of 1.05 Ohms and operates within a temperature range of -40°C to 125°C. Housed in a standard 1206 (3216 Metric) surface-mount package with dimensions of 3.20mm x 1.60mm x 1.10mm, it complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression for high-frequency noise on single conductors
• Engineered for stable performance across a wide industrial temperature range
• Compact surface-mount footprint suitable for space-constrained circuit board layouts

Chip Ferrite Bead Applications

• Power line filtering for low-current digital circuits
• Signal line noise attenuation in communication interfaces
• EMI suppression in portable electronic devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix '10' against the manufacturer's official part number guide to confirm packaging and compliance status. Ensure the selected variant matches the required impedance tolerance and current handling capabilities for the target application. Cross-reference the datasheet for any recent updates regarding material composition or regulatory changes.

Chip Ferrite Bead Selection Notes

Select this component when a 760 Ohm impedance at 100 MHz is required for noise reduction. The 100mA current rating limits its use to low-power applications; higher current needs require alternative models. The 1.05 Ohm DCR must be evaluated against voltage drop constraints in the specific circuit design.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the LF series from Laird-Signal Integrity Products, which focuses on compact EMI solutions. It serves as a passive filter element to suppress high-frequency interference without introducing significant signal distortion. The 1206 package allows for automated assembly in standard SMT production lines.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include the LF1206C202R-10, which offers similar form factors but different electrical characteristics. Designers should verify that any replacement maintains the required impedance profile and current handling capacity to ensure circuit integrity.
