Overview
The ACML-0402-301-T is a multilayer ferrite chip bead from the Abracon ACML series, designed for surface-mount technology in a compact 0402 (1005 metric) package measuring 1.0 mm x 0.5 mm x 0.5 mm. It provides an impedance of 300 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 650 mOhms. It operates reliably within a temperature range of -55°C to +125°C.
Feature Summary
- Multilayer construction enables high-density mounting in space-constrained designs
- Provides effective electromagnetic interference suppression through controlled impedance characteristics
- Capable of handling specified DC bias currents without saturation
Applications
- High-speed data line filtering
- Power supply noise attenuation
- Clock signal integrity management
Procurement Notes
Verify the specific impedance value and DC current rating against the official Abracon datasheet prior to integration. Confirm that the 0402 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series variants.
Selection Notes
Select this component when a low-current application requires significant attenuation at 100 MHz within a minimal footprint. The 100 mA current rating limits suitability for high-power rails. Compare the 650 mOhm DC resistance impact on voltage drop against circuit requirements. Consider the ACML-H series if higher current capacity is necessary for the same package size.
Part Context
This component belongs to the Abracon ACML family of passive ferrite beads. These parts are engineered for general-purpose EMI suppression in consumer electronics and telecommunications equipment. The ACML series offers various impedance values and current ratings across standard SMD packages to support diverse filtering needs.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative manufacturers by matching impedance, current rating, and physical dimensions.
