Overview
The ACML-0402-070-T is a multilayer ferrite chip bead from the Abracon ACML series, designed for surface-mount technology. It features a 0402 (1005 metric) package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 7 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 50 mOhms. The device operates within a temperature range of -55°C to +125°C and carries a tolerance of 25%.
Feature Summary
- Multilayer ferrite construction for effective high-frequency noise suppression
- Compact 0402 surface-mount footprint suitable for space-constrained designs
- High current handling capability of 500 mA for power line applications
Applications
- Noise filtering on DC power supply lines
- EMI suppression in portable electronic devices
- Signal integrity improvement in high-speed digital circuits
Procurement Notes
Verify the specific impedance value and current rating against the official Abracon datasheet prior to procurement. Confirm that the 0402 package dimensions align with the target PCB land pattern. 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 low impedance at 100 MHz is required alongside high current capacity. The 500 mA rating distinguishes it from lower-current variants in the same package size. Consider the 50 mOhm DC resistance for voltage drop calculations in sensitive power rails. The wide temperature range supports operation in harsh industrial or automotive environments.
Part Context
This part belongs to the Abracon ACML family of multilayer ferrite chip beads. These components are engineered to suppress electromagnetic interference in compact electronic systems. The 0402 form factor allows for dense circuit board layouts while maintaining effective noise attenuation characteristics across a broad frequency spectrum.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative ferrite beads by matching impedance curves, current ratings, and physical dimensions.
