FCB-0805-181P

Chip Ferrite Bead Overview

The FCB-0805-181P is a single-channel power line ferrite bead manufactured by Signal Transformer. It features an SMD/SMT termination style within a 0805 (2012 metric) package. The component provides an impedance of 180 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 2.5 A and has a maximum DC resistance of 50 mOhms. The device operates within a temperature range up to +125 C.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies
• Designed for surface mount integration into printed circuit boards
• Capable of handling significant direct current loads without saturation

Chip Ferrite Bead Applications

• Power line filtering in electronic circuits
• Noise suppression on data or power traces
• EMI reduction in compact consumer electronics

Chip Ferrite Bead Procurement Notes

Verify the manufacturer designation as Signal Transformer, distinct from Bel Signal Transformer entities found in broader searches. Confirm the impedance value of 180 Ohms at 100 MHz matches design requirements. Ensure the 0805 footprint and 2.5 A current rating are compatible with the target PCB layout and thermal management strategy before ordering.

Chip Ferrite Bead Selection Notes

Select this component when a low-profile surface mount solution is required for noise attenuation on lines carrying up to 2.5 A. The 180 Ohm impedance at 100 MHz targets common high-frequency interference. Compare the 50 mOhms DC resistance against voltage drop constraints in the specific application circuit to ensure efficient power transmission.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the FCB series of chip inductors and beads designed for signal integrity and power line conditioning. The 0805 case size offers a balance between current handling capability and board space efficiency. It serves as a passive component to attenuate high-frequency noise while maintaining low insertion loss for the desired signal bandwidth.

Chip Ferrite Bead Replacement Considerations

Direct substitutes must match the 0805 footprint, 180 Ohms impedance at 100 MHz, and 2.5 A current rating. Verify that alternative manufacturers provide equivalent DC resistance and operating temperature limits to ensure functional parity in the existing assembly.
