2176745-2

Overview

The TE Connectivity 2176745-2 is a high-current multilayer ferrite chip bead in the BMC-Q automotive grade series. It features a 1204 (3216 metric) surface-mount package with dimensions of 3.2 mm length, 1.6 mm width, and 0.9 mm height. The component provides an impedance of 5 ohms at 100 MHz and supports a maximum DC current of 800 mA. It has a maximum DC resistance of 40 mOhms and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Automotive-grade construction designed for reliability in demanding environments
• Multilayer high-current architecture suitable for power line filtering applications
• Compact 1204 surface-mount footprint for space-constrained PCB layouts

Applications

• Power line noise suppression in automotive electronic systems
• High-current signal integrity management in vehicle control units
• Electromagnetic interference filtering in automotive power distribution networks

Procurement Notes

Verify the specific impedance tolerance and DC current rating against the official datasheet before integration. Confirm that the 1204 package dimensions match the target PCB land pattern. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a low-impedance path is required for high-frequency noise while maintaining high current handling capability. The 5-ohm impedance at 100 MHz offers minimal impact on DC power delivery. The 800 mA rating ensures stability under heavy load conditions typical in automotive power circuits. Consider the 1204 size for balancing performance and board space.
