ABBK00321611121Y00

Overview

The ABBK00321611121Y00 is a shielded surface-mount ferrite bead from Pulse Electronics, designed for single-line noise suppression in electronic circuits. It features a 1206 (3216 metric) package with an impedance of 120 ohms at 100 MHz and a maximum DC resistance of 200 milliohms. The component supports a maximum DC current of 500 mA and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated magnetic shielding reduces electromagnetic interference coupling between adjacent circuit traces.
• High-frequency attenuation characteristics provide effective noise suppression for signal lines.
• Robust construction ensures stable performance across wide industrial temperature variations.

Applications

• Noise filtering on high-speed digital data interfaces
• Power line decoupling in compact mobile devices
• Signal integrity enhancement in automotive electronics

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to integration. Confirm that the selected package footprint matches the PCB layout requirements. Ensure the operating environment remains within the specified thermal limits to maintain component reliability and electrical performance standards.

Selection Notes

Select this component when space-constrained designs require shielded ferrite beads for EMI reduction. The 1206 form factor balances size and current handling capabilities. Evaluate the 500 mA current rating against peak load conditions to prevent saturation. Consider the shielded design for dense layouts where crosstalk mitigation is critical for system stability.

Part Context

This part belongs to the ABBK series of shielded ferrite beads manufactured by Pulse Electronics. The series targets applications requiring reliable noise suppression in limited board real estate. The standardized 1206 dimensions facilitate automated assembly processes common in modern consumer and industrial electronics manufacturing workflows.

Replacement Considerations

Cross-reference alternative shielded ferrite beads with identical 1206 footprints and comparable 120-ohm impedance ratings. Verify that substitute components meet or exceed the 500 mA current handling and -55°C to +125°C temperature specifications to ensure functional equivalence.
