1-2176748-9

Overview

The 1-2176748-9 is a ferrite chip bead manufactured by TE Connectivity Passive Product. It belongs to the Sigma Inductors product line and is designed for data line filtering applications. The component features an 0805 surface mount package with dimensions of 2.0 mm in length, 1.25 mm in width, and 1.0 mm in height. It provides an impedance of 300 Ohms at a frequency of 100 MHz. The device supports a maximum DC current rating of 1 Ampere and has a maximum DC resistance of 250 milliohms.

Feature Summary

• Provides high impedance attenuation for noise suppression on data lines
• Utilizes a compact 0805 surface mount footprint for space-constrained designs
• Engineered to handle high DC current loads without saturation

Applications

• Data line filtering
• Power supply noise suppression
• High-speed signal integrity protection

Procurement Notes

Verify the specific impedance tolerance and DC current ratings against the official datasheet before integration. Confirm that the 0805 package dimensions align with the PCB land pattern requirements. Ensure the operating temperature range meets the environmental specifications of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when designing circuits requiring significant noise attenuation on data lines within an 0805 form factor. The 300 Ohm impedance at 100 MHz makes it suitable for suppressing interference in mid-frequency ranges. Consider the 1A current rating to ensure the component does not saturate under peak load conditions. Evaluate the low DC resistance to minimize voltage drop across the filter in power-sensitive applications.

Part Context

This ferrite bead is part of the Sigma Inductors passive product portfolio from TE Connectivity. It is categorized as a data line filter component. The 0805 package size offers a balance between performance and board space efficiency. It is intended for use in electronic systems where signal integrity must be maintained against electromagnetic interference.
