MAF1005GAD262AT000

Chip Ferrite Bead Overview

The MAF1005GAD262AT000 is a shielded ferrite bead noise suppression filter from the TDK MAF-G series, designed for audio line applications. It features a 0402 (1005 metric) SMD/SMT package with dimensions of 1 mm length, 0.5 mm width, and 0.55 mm height. The component exhibits an impedance of 400 Ohms at 100 MHz and supports a maximum DC current of 300 mA. Its maximum DC resistance is 1.2 Ohms. The device operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Utilizes proprietary low-distortion ferrite material to ensure high audio quality while suppressing cellular band noise between 600 MHz and 2.7 GHz.

Chip Ferrite Bead Applications

• Audio line noise suppression
• Cellular band suppression

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value against official datasheets, as sources vary between 350 Ohms and 400 Ohms at 100 MHz. Confirm the package type is 0402 and check RoHS compliance details. Ensure the selected variant matches the required current rating of 300 mA for the target circuit design.

Chip Ferrite Bead Selection Notes

Select this component for circuits requiring compact noise filtering in audio paths. The low DC resistance minimizes signal loss, while the shielded construction prevents magnetic interference. Verify that the 300 mA current rating exceeds the maximum expected load current in the application.

Chip Ferrite Bead Part Context

This part belongs to the TDK MAF-G series of noise suppression filters. The series was expanded with new products featuring lower DC resistance and higher rated currents up to 1.25 A. These components are engineered to suppress high-frequency noise in sensitive audio lines without degrading signal integrity.

Chip Ferrite Bead Replacement Considerations

Check for other MAF1005GAD variants with different impedance values if the 400 Ohm specification does not match the design requirements. Ensure any substitute maintains the 0402 footprint and compatible thermal characteristics.
