1-2176749-7

Overview

The TE Connectivity Passive Product component 1-2176749-7 is a single-line power line ferrite bead designed for surface mount applications. It utilizes a 1206 (3216 Metric) package format to provide compact footprint integration within electronic circuits. The device exhibits an impedance of 120 Ohms at a test frequency of 100 MHz, ensuring effective high-frequency noise attenuation. It supports a maximum current rating of 4 Amperes, allowing it to handle substantial power loads without saturation. This configuration makes it suitable for filtering applications in power supply lines where both high current capacity and specific impedance characteristics are required.

Feature Summary

• Single-line power line ferrite bead construction
• Surface mount design for automated assembly
• High current handling capability
• Defined impedance profile for noise suppression

Applications

• Power supply input filtering
• DC-DC converter output stages
• High-current signal line noise suppression

Procurement Notes

Verify the exact manufacturer part number against official TE Connectivity documentation before procurement. Confirm that the 1206 package dimensions and 120 Ohm impedance specifications match your circuit requirements. Ensure compatibility with your manufacturing process regarding surface mount technology standards. Check for any recent product change notices or lifecycle status updates directly from the manufacturer to avoid obsolescence risks during production.

Selection Notes

Select this component when a single-channel ferrite bead is needed for high-current power lines. The 1206 package offers a balance between current capacity and board space. The 120 Ohm impedance at 100 MHz targets specific noise frequencies common in switching power supplies. Ensure the 4A current rating exceeds the maximum operating current of the protected line to prevent performance degradation.
