MMZ2012S301ATD25

Overview

The MMZ2012S301ATD25 is a single-line ferrite bead from the TDK MMZ series, designed for surface-mount applications in the 0805 (2012 Metric) package. It provides an impedance of 300 Ohms at 100 MHz with a maximum DC resistance of 200 mOhms and a rated current of 600 mA. The component operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive standards. Measuring 2.00mm x 1.25mm x 1.05mm, it is RoHS compliant and suitable for signal line noise suppression.

Feature Summary

• Provides effective electromagnetic interference suppression for high-frequency signal lines
• Automotive-grade reliability certified under AEC-Q200 standards
• Low DC resistance design minimizes power loss in signal paths

Applications

• Signal line noise filtering in automotive electronic control units
• EMI suppression in automotive multimedia and telematics systems
• Noise reduction in body control modules

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the part matches the specific MMZ2012S301ATD25 designation, as similar packages may have different impedance values. Check for recent Product Change Notifications regarding manufacturing allocations or obsolescence status before finalizing procurement plans.

Selection Notes

Select this component when a 300 Ohm impedance at 100 MHz is required for signal integrity. Ensure the circuit current does not exceed the 600 mA rating to prevent saturation. The 0805 footprint must be compatible with the PCB layout. Consider the AEC-Q200 qualification if the application involves automotive environments requiring robust thermal and electrical performance.

Part Context

This ferrite bead belongs to the MMZ series, which is specifically engineered for automotive electronics. The series offers various impedance options in standard metric footprints. The MMZ2012S301ATD25 represents the 300 Ohm variant within the 0805 size family, balancing noise suppression capabilities with low insertion loss for sensitive signal lines.

Replacement Considerations

Public confirmed substitute part numbers include MMZ1608S301ATD25 from TDK. Verify that the alternative maintains the required 300 Ohm impedance at 100 MHz and fits the available board space constraints.
