MMZ1608D121CTAH0

Overview

The MMZ1608D121CTAH0 is a surface-mount ferrite chip bead from the TDK MMZ series, designed for signal line applications. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.6 mm height. The component provides an impedance of 120 Ohms at a test frequency of 100 MHz, with a tolerance of ±25%. It supports a maximum DC current of 400 mA and has a maximum DC resistance of 300 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Designed specifically for signal line noise suppression in electronic circuits.
• Complies with AEC-Q200 qualification standards for automotive reliability.
• Utilizes a compact 0603 surface-mount footprint for space-constrained designs.

Applications

• Signal line filtering in automotive electronics
• EMI suppression in consumer devices
• Noise reduction in industrial control systems

Procurement Notes

Verify the specific suffix CT against official TDK documentation to confirm packaging type and tape/reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the part number with the latest datasheet to confirm RoHS compliance and environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a 0603 footprint is required for signal integrity management. The 120 Ohm impedance at 100 MHz suits high-frequency noise attenuation. Verify that the 400 mA current rating exceeds the circuit's peak DC load to prevent saturation. Confirm compatibility with standard SMT reflow processes given the 0.6 mm height profile.

Part Context

This part belongs to the TDK MMZ Auto series, which focuses on ferrite beads qualified for automotive environments. The MMZ1608D121CTAH0 shares core electrical characteristics with other variants in the 1608 metric family, differing primarily in packaging and handling specifications. It serves as a passive component for electromagnetic interference mitigation.

Replacement Considerations

Publicly confirmed substitutes include MMZ1608D121BTD25 and MMZ1608D121CTDH5. These alternatives share identical electrical parameters such as 120 Ohm impedance and 400 mA rating. Verify package height differences, as some variants may have a 0.8 mm height instead of 0.6 mm, affecting board clearance requirements.
