Overview
The Abracon ACML-0402-310-T is a multilayer ferrite chip bead designed for surface-mount applications. It provides an impedance of 31 Ohms at a test frequency of 100 MHz. The component supports a maximum DC current of 300 mA and features a maximum DC resistance of 200 mOhms. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1 mm in length, 0.5 mm in width, and 0.5 mm in height, conforming to the standard 0402 (1005 metric) package size.
Feature Summary
- Multilayer construction for compact high-frequency noise suppression
- Surface-mount termination compatible with automated assembly
- Stable performance across extended industrial temperature ranges
Applications
- High-frequency noise filtering in portable electronic devices
- Electromagnetic interference suppression in mobile communication circuits
- Signal integrity protection in space-constrained PCB layouts
Procurement Notes
Verify the specific manufacturer part number against official Abracon documentation to ensure accuracy. Confirm that the required impedance value and current rating align with the circuit design specifications. Check for RoHS compliance status if environmental regulations apply to the final product assembly process.
Selection Notes
Select this component when a low-profile 0402 footprint is required for EMI filtering. Ensure the operating current does not exceed the 300 mA limit to prevent saturation. Verify that the 31 Ohm impedance at 100 MHz matches the target noise frequency spectrum for effective attenuation in the application circuit.
Part Context
This component belongs to the Abracon ACML series of ferrite chip beads. The series offers various impedance values and current ratings within standardized SMD packages. These components are engineered to suppress electromagnetic interference in digital and RF circuits while maintaining a small form factor suitable for modern miniaturized electronics.
Replacement Considerations
Consult official Abracon substitution guides or distributor cross-reference tools for verified equivalent parts. Ensure any replacement maintains identical impedance characteristics, current handling capabilities, and physical dimensions to fit existing board layouts without modification.
