ACML-0402-471-T

Overview

The ACML-0402-471-T is a multilayer ferrite chip bead from the Abracon ACML series, designed for surface-mount technology in a compact 0402 (1005 metric) package. It provides an impedance of 470 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 100 mA and exhibits a maximum DC resistance of 800 mOhms. It operates within a temperature range of -55°C to +125°C and features SMD/SMT termination types.

Feature Summary

• Multilayer construction for high-density circuit board integration
• Effective noise suppression capability at 100 MHz
• Compact 0402 footprint suitable for space-constrained designs

Applications

• High-speed data line filtering
• Power supply noise attenuation
• RF interference suppression in portable electronics

Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official Abracon documentation to ensure correct impedance and current ratings. Confirm RoHS compliance status and packaging options such as cut tape or reel availability through authorized distributors. Cross-reference datasheet specifications with design requirements before finalizing procurement orders.

Selection Notes

Select this component when a 470 Ohm impedance at 100 MHz is required for noise filtering in tight spaces. Ensure the circuit current does not exceed 100 mA to prevent saturation. Consider the 800 mOhm DC resistance impact on voltage drop. Verify thermal stability requirements align with the -55°C to +125°C operating range for the intended application environment.

Part Context

This ferrite bead belongs to the ACML series, which offers various impedance values in the standard 0402 package. It serves as a passive EMI suppression device, distinct from inductors by its resistive behavior at high frequencies. The series is engineered for consumer and industrial electronics requiring reliable noise reduction without significant size penalties.

Replacement Considerations

Consult official Abracon substitution guides for compatible alternatives. Verify that any substitute matches the 470 Ohm @ 100 MHz impedance, 100 mA current rating, and 0402 package dimensions. Ensure equivalent DC resistance and temperature characteristics are maintained for circuit performance consistency.
