MZA3216R121A

Overview

The TDK MZA3216R121A is a four-line ferrite bead array designed for signal line noise suppression in surface-mount applications. It features an impedance of 120 Ohms at 100 MHz and a maximum DC resistance of 180 milliohms per line. The component operates with a rated current of 250 mA and maintains a tolerance of ±25%. Housed in a standard 1206 (3216 Metric) package, it measures 3.2 mm in length, 1.6 mm in width, and has a maximum height of 1.00 mm.

Feature Summary

• Provides multi-channel noise attenuation for high-speed digital signals
• Compact surface-mount footprint suitable for dense PCB layouts
• Low DC resistance minimizes signal loss across data lines

Applications

• High-speed interface circuits requiring EMI suppression
• USB and other differential data bus protection
• General-purpose signal line filtering in consumer electronics

Procurement Notes

Verify the specific revision status before procurement as this part may be subject to product change notifications or end-of-life transitions. Confirm that the 1206 package dimensions and pinout align with the target PCB land pattern. Ensure the 250 mA current rating meets the operational requirements of the specific signal lines to prevent saturation or excessive heating during normal operation.

Selection Notes

Select this component when multiple signal lines require simultaneous noise suppression within a confined space. The four-line configuration offers a cost-effective alternative to discrete beads for parallel data buses. Consider the 120 Ohm impedance profile against the target frequency spectrum to ensure effective attenuation without compromising signal integrity for the specific application bandwidth.

Part Context

This ferrite bead array belongs to TDK's general-purpose noise suppression portfolio. It utilizes multilayer ceramic technology to provide consistent performance across varying environmental conditions. The 1206 form factor allows for automated placement, supporting high-volume manufacturing processes common in modern electronic assembly.
