ACMS451616A851 RDC1

Overview

The ACMS451616A851 RDC1 is a multilayer high-current ferrite chip bead designed for power line EMI suppression. It features an impedance of 850 Ohms at 100 MHz and supports a current rating of 1.5A. The component utilizes an 1806 (4516 Metric) surface mount package with a maximum height of 1.60mm. Its direct current resistance is specified as 100mOhm, ensuring low insertion loss while effectively attenuating noise through its primarily resistive impedance characteristic.

Feature Summary

• Multilayer construction for high-current power line applications
• Primarily resistive impedance for effective noise attenuation
• Surface mount design in standard 1806 package

Applications

• Power line EMI suppression
• Automotive electronics noise filtering
• High-current circuit protection

Procurement Notes

Verify the specific suffix RDC1 against the manufacturer's official datasheet to confirm packaging details and tape-and-reel specifications. Ensure the 1.5A current rating aligns with your circuit's operational requirements. Cross-reference the 850 Ohm impedance value at 100 MHz with your signal integrity needs. Confirm the 1806 footprint compatibility with your PCB layout before finalizing procurement.

Selection Notes

Select this component when high current handling up to 1.5A is required alongside significant impedance at 100 MHz. The 1806 package offers a balance between current capacity and board space. Consider the low DC resistance of 100mOhm to minimize voltage drop in power paths. Evaluate the multilayer technology benefits for robustness in automotive or industrial environments compared to single-layer alternatives.

Part Context

This part belongs to Max Echo's ACMS series of multilayer ferrite chip beads. The series covers various impedance characteristics tailored for SMD applications. The ACMS451616 designation indicates the physical dimensions and series family, while the A851 specifies the impedance profile. This component type is distinct from standard inductors, focusing on broadband noise suppression rather than energy storage.

Replacement Considerations

Consult Max Echo's official substitution guide for equivalent parts within the ACMS series. Verify that any substitute maintains the 1806 footprint and 1.5A current rating. Ensure the replacement offers comparable impedance at 100 MHz and similar DC resistance to preserve circuit performance.
