MMZ2012Y202BT000

Overview

The MMZ2012Y202BT000 is a multi-layer signal line ferrite bead manufactured by TDK Corporation. It utilizes an 0805 (2012 Metric) surface-mount package with dimensions of 2.00mm length, 1.25mm width, and 0.85mm thickness. The component provides an impedance of 2 kOhms at a test frequency of 100 MHz with a tolerance of ±25%. It features a maximum DC resistance of 500 mOhm and supports a rated current of 400mA. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Multi-layer construction for compact signal line filtering
• High impedance characteristics at 100 MHz
• Surface-mount design compatible with standard SMD processes

Applications

• Signal line noise suppression in electronic circuits
• EMI reduction in high-speed digital interfaces
• Power integrity management in compact devices

Procurement Notes

Verify the current production status before procurement, as official sources indicate this specific part number may be scheduled for obsolescence or discontinuation by the manufacturer. Confirm availability through authorized distributors and ensure the datasheet version matches the required specifications. Check for recommended replacement models if active sourcing is necessary for long-term projects.

Selection Notes

Select this component when a 0805 footprint is required for signal line filtering with a target impedance of 2 kOhms at 100 MHz. Ensure the circuit current does not exceed 400mA to prevent saturation. Verify that the thermal environment remains within the -55°C to +125°C operating range. Consider alternative parts if higher current handling or different impedance profiles are needed.

Part Context

This ferrite bead belongs to TDK's MMZ series of multi-layer ceramic components designed for EMI suppression. The 0805 package size offers a balance between performance and board space efficiency. It is commonly used in consumer electronics and industrial equipment where compact noise filtering solutions are required for sensitive signal lines.

Replacement Considerations

Official sources indicate this model is scheduled for obsolescence. Consult TDK documentation for recommended substitute part numbers that maintain equivalent electrical characteristics and package dimensions.
