1-2176744-3

Overview

The TE Connectivity Passive Product component 1-2176744-3 is a single-line power line ferrite bead designed for surface mount applications. It features an 0805 (2012 metric) package with dimensions of 2.0mm length, 1.25mm width, and 1.0mm height. The device provides an impedance of 80 Ohms at 100 MHz and supports a maximum current rating of 2.5A. Its DC resistance is specified at a maximum of 25 milliohms.

Feature Summary

• Provides high-current noise suppression capabilities suitable for power line filtering applications
• Utilizes a compact 0805 surface mount footprint to facilitate automated assembly processes
• Delivers stable impedance characteristics at 100 MHz to effectively attenuate high-frequency electromagnetic interference

Applications

• Power supply output filtering in portable electronic devices
• Noise suppression on data lines within automotive infotainment systems
• EMI mitigation in industrial control board power distribution networks

Procurement Notes

Verify the specific impedance tolerance and current derating curves against your thermal design requirements before finalizing procurement. Confirm that the 0805 package dimensions align with your PCB land pattern specifications. Ensure compliance with RoHS directives if operating in regulated markets. Cross-reference the manufacturer's latest datasheet for any updates regarding material composition or environmental certifications prior to ordering.

Selection Notes

Select this component when a low DC resistance is critical to minimize voltage drop across high-current paths while maintaining effective high-frequency noise attenuation. The 80 Ohm impedance value targets common switching frequency ranges found in modern power converters. Consider the 2.5A current rating to ensure adequate margin for peak load conditions without saturation. The 0805 size offers a balance between current handling capacity and space constraints compared to smaller packages.

Part Context

This ferrite bead belongs to the Sigma Inductors passive product portfolio from TE Connectivity. It is engineered specifically for power line filtering where high current carrying capability is required alongside significant impedance generation. The component addresses EMI/RFI challenges in dense electronic assemblies by providing a targeted frequency-dependent resistive loss mechanism.

Replacement Considerations

Direct substitutes must match the 80 Ohm @ 100 MHz impedance, 2.5A current rating, and 0805 package outline. Verify that alternative components maintain similar DC resistance levels to prevent excessive power loss. Check for equivalent temperature stability and saturation characteristics to ensure circuit performance parity.
