MZAS1005G121-R80TF

Overview

The MZAS1005G121-R80TF is a surface-mount ferrite bead designed for data line filtering applications. It features a single-function configuration with two terminals housed in an EIA STD 0402 package measuring 1 mm in length, 0.5 mm in width, and 0.5 mm in height. The component has a maximum DC resistance of 0.4 Ω and an output impedance of 120 Ω at the specified frequency. It supports a rated current of 0.7 A to 0.8 A and operates within a temperature range of -55 °C to 125 °C.

Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics in compact form factors
• Designed for surface-mount assembly on printed circuit boards
• Constructed for reliable operation across extended industrial temperature ranges

Applications

• Data line noise filtering in electronic circuits
• Signal integrity protection in communication modules
• Power supply decoupling in consumer electronics

Procurement Notes

Verify the specific impedance value and current rating against the official Sunlord datasheet before procurement. Confirm that the 0402 package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check RoHS compliance status if required by your manufacturing standards. Validate the supplier's authorization to guarantee component authenticity.

Selection Notes

Select this component when space constraints require a 0402 footprint for signal filtering. Consider the 0.4 Ω DC resistance limit to minimize voltage drop in low-power lines. Evaluate the 120 Ω impedance profile against the target noise frequencies. Ensure the rated current capacity exceeds the peak operational current of the protected circuit to prevent saturation or overheating.
