MMZ1608A182BTD25

Overview

The MMZ1608A182BTD25 is a single-line ferrite chip bead from the MMZ Auto series, manufactured by TDK Corporation. Designed for signal line applications, 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 1.8 kOhms at a test frequency of 100 MHz and supports a maximum DC current of 200 mA. It exhibits a maximum DC resistance of 800 mOhms with a 25% tolerance. Certified to AEC-Q200 standards, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Automotive-grade reliability certified under AEC-Q200 standards for robust performance in vehicle electronics.
• High impedance characteristics optimized for effective suppression of high-frequency noise on signal lines.
• Flexible soft terminals designed to enhance mechanical durability and prevent solder joint cracking during board flexing.

Applications

• Noise suppression in automotive electronic control units
• Signal line filtering in infotainment systems
• EMI reduction in automotive sensor interfaces

Procurement Notes

Verify the complete part number including suffixes to ensure correct impedance and tolerance specifications. Confirm AEC-Q200 certification status if automotive qualification is required. Check datasheet for specific thermal derating curves relative to ambient operating conditions. Ensure compatibility with standard reflow soldering profiles defined for 0603 packages.

Selection Notes

Select this component when high attenuation is required for signal integrity rather than power rail filtering due to its low current rating. Compare against the KMZ-HR series if higher current handling or different impedance profiles are needed. Consider the 0603 footprint constraints and verify that the 200 mA rating aligns with the target circuit's operational current limits.

Part Context

This ferrite bead belongs to the MMZ Auto series, specifically engineered for automotive environments. It complements other components in the MMZ1608 family, offering standardized 0603 dimensions for easy integration into compact PCB layouts. The series focuses on providing reliable EMI suppression solutions tailored for the stringent requirements of modern vehicle electronics.

Replacement Considerations

Equivalent parts include MMZ1608A121BTD25 for lower impedance needs or MMZ1608YHR600BTD25 for higher current capacity. Verify that substitute components maintain the same 0603 footprint and AEC-Q200 certification to ensure direct interchangeability without redesigning the layout.
