MMZ1608R121CTAH0

Overview

The TDK MMZ1608R121CTAH0 is a surface-mount ferrite chip bead designed for signal line filtering. It features an impedance of 120 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 500 mA. The component has a maximum DC resistance of 250 mOhms with a tolerance of 25%. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1.6 mm in length, 0.8 mm in width, and 0.6 mm in height, conforming to the 0603 (1608 metric) package.

Feature Summary

• Provides electromagnetic interference suppression on signal lines through high-impedance characteristics at target frequencies.
• Supports continuous DC currents up to 500 mA while maintaining low DC resistance to minimize signal loss.
• Engineered for reliable operation across extended industrial temperature ranges from -55°C to +125°C.

Applications

• Signal line filtering in electronic circuits
• Electromagnetic interference suppression in compact devices

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before initiating new projects, as this indicates potential future discontinuation. Confirm RoHS compliance details via the official datasheet. Ensure the 0603 footprint matches the PCB layout requirements. Check for specific packaging options such as cut tape or reel availability if standard quantities are required.

Selection Notes

Select this component when a 120 Ohm impedance at 100 MHz is required for signal integrity. The 500 mA current rating suits moderate power applications. Compare against automotive-grade alternatives like the MMZ1608R121ATD25 if AEC-Q200 certification is mandatory. Verify that the 250 mOhms DC resistance meets the voltage drop constraints of the specific circuit design.

Part Context

This part belongs to the TDK MMZ series of ferrite beads, which are widely used for noise suppression in portable electronics and general-purpose circuits.
