Overview
The Abracon ACML-0805-122-T is a single-channel ferrite chip bead designed for surface-mount technology. It operates within a temperature range of -55°C to +125°C and features an impedance of 1200 Ohms at 100 MHz. The component supports a maximum DC current of 200 mA with a tolerance of 25%. Its physical dimensions are 2 mm in length, 1.25 mm in width, and 0.85 mm in height. The maximum DC resistance is specified at 650 mOhms.
Feature Summary
- Provides high-frequency noise suppression through ferrite material properties
- Supports surface-mount assembly for automated PCB integration
- Operates reliably across extended industrial temperature ranges
Applications
- Office automation equipment signal line filtering
- Video equipment power distribution noise reduction
- Audio equipment interference mitigation
- Communication device EMI suppression
Procurement Notes
Verify the specific impedance value and current rating against circuit requirements before ordering. Confirm RoHS compliance status as indicated in official documentation. Ensure the 0805 package footprint matches the design layout. Check for any automotive qualification requirements if applicable to the end application.
Selection Notes
Select this component when high impedance at 100 MHz is required for noise attenuation. The 200 mA current rating suits low-power signal lines or auxiliary power rails. Consider the 650 mOhm DC resistance impact on voltage drop. The unshielded construction is suitable for general EMI control where magnetic shielding is not critical.
Part Context
This part belongs to the ACML series of ferrite chip beads from Abracon. It utilizes a monolithic ferrite structure to dissipate high-frequency energy as heat. The 0805 package provides a balance between current handling capability and board space efficiency compared to smaller footprints.
Replacement Considerations
Cross-reference with other 0805 ferrite beads offering 1200 Ohms impedance at 100 MHz and similar current ratings. Verify that substitute components match the physical dimensions and terminal configuration for direct replacement.
