MMZ2012S301AT000

Overview

The MMZ2012S301AT000 is a single-line ferrite bead in an 0805 (2012 Metric) surface-mount package. It provides 300 Ohms impedance at 100 MHz with a maximum DC resistance of 200mOhm and a current rating of 600mA. The component operates within a temperature range of -55°C to +85°C, offering noise reduction for general signal lines.

Feature Summary

• Provides effective noise suppression for high-frequency interference on signal traces
• Designed for surface-mount assembly using standard reflow soldering processes
• Utilizes specific ferrite materials to target various frequency characteristics

Applications

• Noise reduction solutions for general signal lines
• Power supply circuits requiring EMI filtering
• Battery charger input/output stages

Procurement Notes

Verify the complete part number including suffixes against official TDK documentation to ensure correct material selection and impedance profile. Confirm that the 0805 package dimensions align with the PCB footprint design. Ensure the selected variant meets the required operating temperature range and current handling capabilities for the specific application environment.

Selection Notes

Select this component when a 300 Ohm impedance at 100 MHz is required for signal integrity. The 600mA current rating suits low-power signal lines rather than high-current power rails. Consider the 200mOhm DCR impact on voltage drop if used in sensitive bias networks. Evaluate thermal performance under continuous load conditions.

Part Context

This ferrite bead belongs to TDK's MMZ series, which offers multiple material options for different frequency attenuation profiles. The 0805 package size balances component density with thermal dissipation capabilities. It serves as a passive filter element to suppress electromagnetic interference without introducing significant signal distortion in the passband.

Replacement Considerations

Substitute only with components sharing identical 300 Ohm @ 100 MHz impedance, 600mA rating, and 0805 footprint. Verify equivalent DC resistance and temperature coefficients to maintain circuit performance.
