MZA1210D680C

Overview

The TDK MZA1210D680C is a surface-mount ferrite bead array designed for general signal line applications. It features a dual-line configuration within a compact 0504 (1210 metric) package, measuring 1.25 mm in length, 1.00 mm in width, and 0.60 mm in height. The component provides an impedance of 68 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 50 mA and exhibits a maximum DC resistance of 500 mOhms. The device operates reliably across a temperature range from -55°C to +125°C.

Feature Summary

• Dual-line ferrite bead array structure for multi-signal noise suppression
• Compact 0504 surface-mount footprint for high-density PCB layouts
• High-temperature stability suitable for demanding operational environments

Applications

• General signal line filtering
• Data bus protection
• High-speed interface noise suppression

Procurement Notes

Verify the current manufacturing status before procurement as this specific part number is listed as obsolete by major distributors. Confirm availability through authorized channels or check for valid replacement alternatives. Ensure that any substitute components meet the original electrical specifications, including impedance, current rating, and physical dimensions, to maintain circuit integrity and compliance.

Selection Notes

Select this component when space-constrained designs require dual-channel noise attenuation on signal lines. The 68 Ohm impedance value targets specific frequency ranges around 100 MHz. Verify that the 50 mA current rating exceeds the peak operating current of the protected lines. The wide temperature range ensures functionality in harsh industrial or automotive conditions where standard commercial parts might fail.

Part Context

This component belongs to the TDK MZA series of chip bead arrays. These devices are engineered for suppressing electromagnetic interference in digital circuits. The 1210 metric package size balances performance with board space efficiency. The series is widely used in consumer electronics and industrial equipment requiring reliable signal integrity management.

Replacement Considerations

Public sources indicate this product is no longer manufactured. Users should consult official TDK documentation for confirmed substitute part numbers. Do not assume generic equivalents match the specific impedance curve or thermal characteristics without verifying datasheet alignment.
