Overview
The ACML-0402-221-T is a multilayer ferrite chip bead manufactured by Abracon LLC. It features an impedance of 220 ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current rating of 150 mA and has a maximum DC resistance of 450 milliohms. It operates within a temperature range of -55°C to +125°C. The device utilizes SMD/SMT termination and is housed in a 0402 (1005 metric) package measuring 1 mm in length, 0.5 mm in width, and 0.5 mm in height.
Feature Summary
- Multilayer ferrite construction for compact surface-mount integration
- High impedance performance at 100 MHz for effective noise suppression
- Wide operating temperature range suitable for diverse environmental conditions
Applications
- Power supply line filtering
- Data line noise suppression
- General-purpose EMI/RFI attenuation in portable devices
Procurement Notes
Verify the specific impedance value and current rating against the official Abracon datasheet prior to implementation. Confirm that the 0402 package dimensions align with the target PCB footprint. Ensure the selected component meets RoHS compliance requirements if mandated by the end-product specifications. Cross-reference the manufacturer part number to avoid confusion with similar series variants.
Selection Notes
Select this component when a low-profile ferrite bead is required for high-frequency noise reduction in space-constrained designs. The 150 mA current rating makes it suitable for low-power signal lines or auxiliary power rails. Consider the 450 milliohm DC resistance impact on voltage drop for sensitive circuits. The wide temperature range ensures reliability across various operational environments without derating concerns.
Part Context
This component belongs to the ACML series of multilayer ferrite chip beads from Abracon. These components are designed to suppress electromagnetic interference in high-speed digital and RF circuits. The 0402 form factor allows for dense board layouts common in modern consumer electronics and communication equipment.
Replacement Considerations
Direct substitutes include other 0402 ferrite beads with 220 ohms impedance at 100 MHz and comparable current ratings. Verify pin compatibility and thermal characteristics before swapping manufacturers.
