MMZ2012S181AT000

Overview

The TDK MMZ2012S181AT000 is a single-line ferrite bead in the MMZ series, designed for signal line filtering. It features an impedance of 180 Ohms at 100 MHz and supports a maximum current rating of 600 mA. The component has a maximum DC resistance (DCR) of 150 mOhm. It utilizes a 0805 (2012 Metric) surface-mount package with dimensions of 2.00 mm length, 1.25 mm width, and 0.85 mm height. The device operates within a temperature range of -55°C to 125°C and holds AEC-Q200 qualification.

Feature Summary

• Provides electromagnetic interference suppression for high-speed signal lines through frequency-dependent impedance characteristics.
• Engineered for automotive applications with AEC-Q200 reliability certification.
• Utilizes a compact 0805 surface-mount footprint to facilitate automated assembly and space-constrained designs.

Applications

• High-speed data interface noise suppression
• Automotive electronic circuit protection
• Signal integrity enhancement in digital systems

Procurement Notes

Verify the specific suffix 'TD25' versus 'T000' as packaging or lot codes may differ. Confirm end-of-life status via official PCN documents before finalizing design-in decisions. Ensure compatibility with reflow soldering profiles specified in the manufacturer's datasheet. Validate that the 600mA current rating meets the peak operational requirements of the target circuit without exceeding thermal limits.

Selection Notes

Select this component when a 180 Ohm impedance at 100 MHz is required for EMI filtering on single-ended signals. The 0805 package size offers a balance between current handling capability and board space efficiency. Consider the 150 mOhm DCR impact on voltage drop if the operating current approaches the 600 mA maximum rating. Ensure the application environment remains within the -55°C to 125°C operating temperature range for optimal performance.
