ACML-0805-121-T

Overview

The Abracon ACML-0805-121-T is a surface-mount ferrite bead from the ACML-0805 series, designed for electromagnetic interference suppression. It features an impedance of 120 ohms at 100 MHz and supports a maximum DC current rating of 800 mA. The component has a maximum DC resistance of 150 milliohms and operates within a temperature range of -55°C to +125°C. Housed in a standard 0805 (2012 metric) package with dimensions of 2.0 mm length, 1.25 mm width, and 0.85 mm height, it provides reliable noise filtering for compact electronic designs.

Feature Summary

• Provides effective high-frequency noise attenuation through ferrite material properties
• Supports continuous DC currents up to 800 mA without saturation
• Offers low DC resistance to minimize signal loss in power lines
• Compatible with standard surface mount assembly processes

Applications

• Portable communication devices
• Automotive electrical systems
• Audio equipment signal conditioning
• Video processing circuits

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the manufacturer's latest datasheet before finalizing design specifications. Confirm that the 0805 package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your environmental conditions. Check for RoHS compliance documentation if required by your regulatory standards. Validate the supplier's authenticity to avoid counterfeit components.

Selection Notes

Select this component when a 120 ohm impedance at 100 MHz is required for EMI suppression in space-constrained applications. The 800 mA current rating makes it suitable for moderate power line filtering. Consider the 0805 package size relative to available board real estate. Compare the 150 milliohm DC resistance against other options to ensure minimal voltage drop. Evaluate thermal performance within the specified -55°C to +125°C range for your specific environment.

Part Context

This part belongs to Abracon's ACML-0805 series of chip ferrite beads. The series offers various impedance and current ratings within the 0805 footprint. These components are engineered for general-purpose noise suppression in consumer electronics and industrial equipment. The standardized dimensions facilitate automated placement and consistent soldering results across production runs.

Replacement Considerations

Cross-reference with other 0805 ferrite beads offering 120 ohms at 100 MHz and similar current ratings. Verify package compatibility and impedance tolerance matches. Ensure thermal characteristics align with existing design constraints.
