Overview
The TDK MMZ1608S181ATD25 is a ferrite chip bead designed for signal line applications within the MMZ Auto series. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 180 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 200 mOhms. Operating temperatures range from -55°C to +125°C. The part holds AEC-Q200 qualification for automotive reliability.
Feature Summary
- AEC-Q200 qualified for automotive electronic applications
- Designed specifically for signal line noise suppression
- Compact 0603 surface-mount form factor
Applications
- Automotive signal circuit noise filtering
- High-frequency interference suppression in compact electronics
- Signal integrity protection in automotive modules
Procurement Notes
Verify the complete part number including suffix TD25 to ensure correct packaging configuration. Confirm AEC-Q200 certification status if automotive compliance is required. Check RoHS documentation for environmental compliance details. Ensure the 180 Ohm impedance rating matches the target frequency requirements of the specific signal line application.
Selection Notes
Select this component when a 0603 footprint is required for signal lines rather than power rails. The 500 mA current rating suits low-current signal paths. Verify that the 180 Ohm impedance at 100 MHz aligns with the noise spectrum to be suppressed. Consider the -55°C to +125°C temperature range for harsh environment suitability.
Part Context
This component belongs to the TDK MMZ Auto series, which focuses on ferrite beads certified for automotive use. The MMZ1608S181ATD25 shares the standard 0603 mechanical outline with other variants in the series but differs in impedance and current handling characteristics based on its specific material composition and design parameters.
Replacement Considerations
Substitute parts must match the 0603 footprint, 180 Ohm impedance at 100 MHz, and 500 mA current rating. Automotive applications require equivalent AEC-Q200 qualification. Verify DC resistance and temperature range compatibility before integration.
