Overview
The ACML-0402HC-301-T is a multilayer ferrite chip bead from the Abracon ACML-HC series, designed for surface-mount technology in the 0402 (1005 metric) package. It provides an impedance of 300 Ohms at a test frequency of 100 MHz with a maximum DC current rating of 1 A. The component features a maximum DC resistance of 300 mOhms and a tolerance of ±25%. It operates within a temperature range of -55°C to +125°C and has physical dimensions of 1.0 mm in length, 0.5 mm in width, and 0.5 mm in height.
Feature Summary
- High current handling capability up to 1 A for power line noise suppression
- Compact 0402 footprint suitable for space-constrained PCB layouts
- Multilayer construction for stable high-frequency attenuation characteristics
Applications
- Noise filtering on high-current power supply rails
- EMI suppression in portable electronic devices
- Signal integrity enhancement in compact consumer electronics
Procurement Notes
Verify that the specific part number matches the required impedance and current ratings for your design. Confirm the packaging format, such as tape and reel or cut tape, aligns with your assembly equipment capabilities. Ensure the manufacturer is Abracon LLC to guarantee compliance with the specified electrical parameters and quality standards.
Selection Notes
Select this component when a 0402 package size is required alongside a high current rating of 1 A. The 300 Ohm impedance at 100 MHz makes it suitable for broadband noise suppression. Consider the low DC resistance of 300 mOhms to minimize voltage drop and power loss in the circuit path compared to higher resistance alternatives.
Part Context
This component belongs to the ACML-HC series, which distinguishes itself through enhanced current handling capabilities compared to standard ferrite beads. The HC designation indicates optimized materials for applications requiring robust performance under higher load currents while maintaining effective electromagnetic interference suppression in small form factors.
Replacement Considerations
Direct substitutes include other 0402 ferrite beads with similar 300 Ohm impedance and 1 A current ratings. Verify that alternative parts match the 300 mOhm maximum DC resistance and operate within the same -55°C to +125°C temperature range to ensure equivalent thermal and electrical performance.
