MZA3216D121C

Overview

The MZA3216D121C is a surface-mount ferrite bead array manufactured by TDK Corporation. It features a 1206 (3216 metric) package with four independent signal lines. The component provides an impedance of 120 Ohms at 100 MHz and has a maximum DC resistance of 450 milliohms per line. It supports a rated current of 200 mA and operates within a temperature range of -55°C to 125°C.

Feature Summary

• Four-channel signal line filtering configuration
• High impedance performance at 100 MHz
• Compact 1206 surface-mount footprint

Applications

• General signal line noise suppression
• Data bus protection in electronic circuits
• EMI reduction for high-speed digital signals

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may vary. Confirm that the 1206 package dimensions align with your PCB layout constraints. Ensure the 200mA current rating meets the operational requirements of your target circuit to prevent saturation or overheating during normal use.

Selection Notes

Select this component for applications requiring multi-line EMI suppression in space-constrained designs. The 120-ohm impedance at 100 MHz makes it suitable for general-purpose signal integrity improvement. Consider the 450-milliohm DC resistance impact on voltage drop if low-power signals are involved.

Part Context

This part belongs to TDK's MZA series of chip beads designed for general signal lines. It utilizes a monolithic ceramic structure to provide effective common-mode and differential-mode noise attenuation. The 1206 package allows for automated placement in standard SMT assembly processes.
