FCM 2012KF-121T08

Chip Ferrite Bead Overview

The FCM 2012KF-121T08 is a single-line EMI suppression filter manufactured by TAI-TECH Advanced Electronics Co., Ltd. It features an impedance of 120 Ohms at a test frequency of 100 MHz and a maximum DC resistance (RDC) of 200 milliohms. The component supports a rated current of 800 mA and utilizes the 0805 (2012 Metric) surface-mount package.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics at specific frequencies
• Designed for surface-mount integration within compact electronic assemblies
• Constructed as a multi-layer ferrite chip inductor for signal line protection

Chip Ferrite Bead Applications

• Signal line noise filtering in portable devices
• EMI suppression in consumer electronics circuits
• High-frequency noise attenuation in data transmission lines

Chip Ferrite Bead Procurement Notes

Verify the exact part number against manufacturer documentation to ensure compatibility with design specifications. Confirm that the 0805 package dimensions align with PCB footprint requirements. Check for RoHS compliance status if environmental regulations apply to the final product assembly. Ensure the rated current and impedance values meet the circuit's operational needs.

Chip Ferrite Bead Selection Notes

Select this component when a low-profile, single-line ferrite bead is required for high-frequency noise reduction. The 120 Ohm impedance at 100 MHz targets specific noise spectra. The 800 mA current rating suits moderate power applications. Consider the 200 mOhm DCR for minimal voltage drop in sensitive signal paths compared to higher-resistance alternatives.

Chip Ferrite Bead Part Context

This model belongs to the FCM series of EMI suppression filters from TAI-TECH. The series includes standard ferrite beads designed for general-purpose noise suppression. The FCM series complements the company's HCB and HFZ lines, which offer high-current or low-DCR variants for different power handling requirements.
