Overview
The ACMS321611A102 1A is a single-line multilayer ferrite chip bead manufactured by Max Echo, designed for power line noise suppression. It features a 1206 (3216 Metric) surface-mount package with dimensions of 3.20mm x 1.60mm and a maximum height of 1.10mm. The component exhibits an impedance of 1 kOhms at 100 MHz and supports a rated current of 1A. Its DC resistance (DCR) is maximized at 300 milliohms. It operates within a temperature range of -55°C to 125°C and complies with RoHS3 standards.
Feature Summary
- Multilayer construction provides high impedance characteristics primarily in the resistive part for effective noise attenuation.
- Single-line design specifically intended for power line EMI suppression applications.
- Surface-mount format allows for automated placement in compact electronic assemblies.
Applications
- Power line filtering in portable electronics
- EMI suppression in automotive electronic modules
- Noise reduction in industrial control systems
Procurement Notes
Verify the manufacturer designation as Max Echo and confirm the specific suffix '1A' corresponds to the 1A rated current and 300mOhm DCR specifications. Ensure the package matches the 1206 metric footprint. Check for RoHS3 compliance status if required by environmental regulations. Confirm lead times and packaging options such as tape and reel or cut tape directly from authorized distributors.
Selection Notes
Select this component when a 1kOhm impedance at 100MHz is required for single-line power filtering. The 1A current rating must accommodate the circuit's operational load without saturation. The 1206 package size should fit the available PCB real estate. Consider the -55°C to 125°C operating range for environmental suitability. Verify that the low DCR meets voltage drop constraints in the power path.
Part Context
This component belongs to the ACMS series of multilayer ferrite chip beads from Max Echo. These components are engineered to suppress electromagnetic interference in high-speed digital circuits and power lines. The series offers various impedance values and current ratings to suit different filtering requirements across consumer, industrial, and automotive sectors.
Replacement Considerations
Consult official substitution lists for equivalent impedance and current ratings. Verify package compatibility and thermal characteristics before replacing. Cross-reference datasheets for identical performance metrics.
