ACML-0603U-181-T

Overview

The ACML-0603U-181-T is a multilayer ferrite chip bead manufactured by Abracon LLC, designed for surface-mount technology applications. It features a 0603 (1608 metric) package with dimensions of 1.6 mm in length and 0.8 mm in width. The component provides an impedance of 180 ohms at a frequency of 100 MHz. It supports a maximum DC current rating of 150 mA and exhibits a maximum DC resistance of 50 milliohms. The device operates within a temperature range from -55°C to +125°C and has a tolerance of 25%.

Feature Summary

• Multilayer construction utilizing ferrite core material for effective high-frequency noise suppression
• Surface-mount design compatible with standard PCB assembly processes
• Single-channel configuration for unidirectional signal line filtering

Applications

• High-speed data line filtering in portable electronic devices
• Power supply noise attenuation in compact circuit boards
• EMI suppression in RF signal paths

Procurement Notes

Verify the specific suffix 'U' against the official Abracon datasheet to confirm it denotes the correct impedance value and package variant, as suffixes can indicate manufacturing revisions or specific parameter tolerances. Ensure the ordering part number matches the required 180 ohm specification at 100 MHz. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and any recent product change notifications that may affect electrical characteristics or physical dimensions.

Selection Notes

Select this component when a low-profile 0603 footprint is required for space-constrained designs. The 150 mA current rating suits moderate power lines, while the 50 milliohm DC resistance minimizes voltage drop. Consider the 180 ohm impedance profile for target noise frequencies around 100 MHz. Evaluate thermal management requirements given the wide operating temperature range up to 125°C.

Part Context

This component belongs to the ACML series of multilayer ferrite beads from Abracon. The series offers various impedance values and package sizes to address different EMI suppression needs. The 0603 form factor balances size efficiency with adequate current handling capabilities compared to smaller packages like 0402.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative ferrite beads based on matching impedance curves, current ratings, and package dimensions before substitution.
