MZA3216R102A

Overview

The MZA3216R102A is a signal line ferrite bead manufactured by TDK Corporation. It features a 1 kOhm impedance rating at 100 MHz and supports a maximum current of 150 mA with a DC resistance of 600 mOhm. The component utilizes a 1206 (3216 Metric) surface mount package configuration, specifically designed as an array with 8 PC pads. This device is classified under the filter category for noise suppression applications.

Feature Summary

• Provides effective signal line noise filtering through high impedance characteristics at target frequencies
• Utilizes a compact surface mount array footprint to facilitate dense circuit board layouts
• Designed for direct integration into power or data lines requiring common-mode or differential noise attenuation

Applications

• Signal line noise suppression in electronic circuits
• EMI/RFI filtering for high-speed digital interfaces
• Power line conditioning for sensitive components

Procurement Notes

Verify the specific datasheet version and impedance curve prior to procurement, as ferrite characteristics can vary significantly with frequency and temperature. Confirm that the 150 mA current rating aligns with the peak operational requirements of the target circuit to prevent saturation. Ensure the 8-pad array footprint matches the PCB land pattern exactly, as standard 1206 footprints differ from this specific array configuration.

Selection Notes

Select this component when a 1 kOhm impedance at 100 MHz is required for noise attenuation. The 150 mA current handling capability limits its use to low-current signal paths rather than main power rails. The 8-pad array design necessitates specific PCB layout considerations compared to standard two-terminal beads. Evaluate thermal dissipation needs given the 600 mOhm DC resistance under load conditions.

Part Context

This part belongs to TDK's ferrite bead and core chip product line, categorized under filters. It serves as a passive component for electromagnetic interference suppression. The 1206 metric size indicates a standard industrial footprint, while the array designation distinguishes it from single-element beads. It is part of the broader family of surface-mount magnetic components used for signal integrity management.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative ferrite beads based on identical impedance curves, current ratings, and physical footprint dimensions before substitution.
