AFBC-SK0402-102T

Overview

The AFBC-SK0402-102T is a ferrite bead from the Abracon AFBC-SK0402 series, designed for surface-mount technology in a 0402 (1005 metric) package. It exhibits an impedance of 1 kohm and supports a maximum DC current rating of 230 mA. The component features a maximum DC resistance of 900 milliohms. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Internal silver lithographic layers facilitate efficient signal transmission while maintaining low resistance characteristics.
• Monolithic inorganic material construction ensures structural integrity and reliability under various environmental conditions.
• Engineered for effective electromagnetic interference suppression at high frequencies to protect sensitive circuitry.

Applications

• High-frequency EMI suppression in compact electronic devices
• Signal integrity protection in mobile communication modules
• Power line filtering in space-constrained PCB designs

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration as per manufacturer standards. Confirm RoHS compliance status through official documentation before integration. Ensure the 0402 footprint matches the target PCB layout dimensions precisely. Cross-reference the 1 kohm impedance value with application frequency requirements to validate performance suitability.

Selection Notes

Select this component when space constraints require a 0402 form factor alongside significant high-frequency noise attenuation. The 230 mA current rating suits moderate power applications where thermal management is critical. Compare against standard AFBC-Q variants if higher current handling or different impedance profiles are required for the specific circuit topology.

Part Context

This part belongs to the AFBC-SK0402 series, which utilizes silver lithography for enhanced conductivity compared to traditional nickel barriers. The series targets consumer electronics and automotive applications requiring robust EMI filtering in minimal board space. It complements Abracon's broader ferrite bead portfolio by offering specialized high-performance characteristics in a standard industry footprint.

Replacement Considerations

Direct substitutes include other 0402 ferrite beads with 1 kohm impedance and similar current ratings. Verify that alternative components maintain compatible DC resistance and operating temperature ranges. Check for pin-out compatibility and solderability specifications to ensure seamless integration without redesigning the existing PCB layout.
