Overview
The ACMS321611A190 is a single-line ferrite bead from the Max Echo ACMS series, designed for power line EMI 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 provides an impedance of 19 Ohms at 100 MHz and supports a rated current of 3A. Its maximum DC resistance is 30 milliohms. It operates within a temperature range of -55°C to 125°C.
Feature Summary
- Provides electromagnetic interference suppression on power lines through high-frequency impedance characteristics.
- Utilizes multilayer ferrite chip technology for compact surface-mount integration.
- Engineered for high-current applications with a 3A rated current capacity.
Applications
- Power line filtering in electronic circuits
- EMI suppression for high-current signal paths
- Noise reduction in portable devices
Procurement Notes
Verify the specific suffix '1A' or equivalent against the datasheet to confirm the 3A rating and 19 Ohm impedance, as series variants may differ. Confirm RoHS3 compliance and MSL level 1 status during sourcing. Ensure the supplier provides official documentation matching the Max Echo ACMS series specifications to avoid substitution errors with similar impedance values.
Selection Notes
Select this component when a low DC resistance of 30 milliohms is required alongside a 3A current handling capability. The 19 Ohm impedance at 100 MHz makes it suitable for suppressing noise in power rails where minimal voltage drop is critical. The 1206 package allows for standard SMT assembly processes.
Part Context
This part belongs to the Max Echo ACMS series of multilayer ferrite chip beads. These components are specifically engineered for EMI suppression in power lines. The series offers various impedance and current ratings within the 1206 footprint, allowing designers to tailor noise filtering performance without changing the board layout.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility carefully if considering alternatives from other manufacturers, as impedance curves and saturation currents may vary significantly.
