MAF1005FRQ102AT000

Chip Ferrite Bead Overview

The MAF1005FRQ102AT000 is a ferrite bead from the TDK MAF-G series, designed for noise suppression in cellular band applications. It features a 0402 (1005 metric) SMD package with dimensions of 1.0 mm length, 0.5 mm width, and 0.55 mm height. The component offers an impedance of 200 Ohms at 900 MHz, a maximum DC current rating of 240 mA, and a maximum DC resistance of 1.65 Ohms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Optimized for cellular band suppression
• Compact 0402 surface mount footprint
• High current handling capability

Chip Ferrite Bead Applications

• Cellular communication circuits
• Audio line noise suppression
• General EMC filtering

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'Q' against official TDK documentation to confirm material composition and tape/reel specifications. Ensure the selected variant matches the required 240 mA current rating and 1.65 Ohm DCR limits for your design. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0402 footprint for high-frequency noise attenuation. The 240 mA rating suits moderate current paths where 200 Ohms impedance at 900 MHz is sufficient for cellular interference reduction. Compare against the MAF1005GAD series if higher current tolerance or different impedance characteristics are needed.

Chip Ferrite Bead Part Context

This part belongs to the TDK MAF-G series of noise suppression filters. The series includes variants like the MAF1005GAD152AT000, which shares the same 0402 package but differs in electrical parameters such as DC resistance and current rating. The MAF1005FR series represents a newer generation focused on compact audio and cellular applications.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other MAF1005 series parts from TDK with matching 0402 footprints. Verify impedance curves and current ratings carefully, as values vary significantly between suffixes like GAD and FRQ.
