Overview
The TE Connectivity Passive Product 2176742-7 is a ferrite chip bead from the BMC-Q series, designed for power line noise suppression. It features a 0402 (1005 metric) surface mount package with an impedance of 120 ohms at 100 MHz and a tolerance of ±25%. The component supports a maximum DC current of 450 mA and has a maximum DC resistance of 250 milliohms. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Provides effective high-frequency noise attenuation on power lines through ferrite material properties.
- Designed for compact surface-mount integration in space-constrained electronic assemblies.
- Engineered to handle specific DC current loads while maintaining signal integrity.
Applications
- Power supply input filtering
- DC-DC converter output stages
- General-purpose EMI suppression in portable devices
Procurement Notes
Verify the exact part number suffix and manufacturing date code upon order confirmation. Ensure that the specified impedance and current ratings align with your circuit design requirements before finalizing procurement. Confirm RoHS compliance status with the supplier if required by your regulatory framework.
Selection Notes
Select this component when a low-profile 0402 footprint is required for power rail filtering. Consider the 450 mA current rating to ensure it exceeds the peak operating current of the protected circuit. Evaluate the 120 ohm impedance at 100 MHz against the target noise frequency spectrum to confirm adequate attenuation performance.
Part Context
This component belongs to the Sigma Inductors family under TE Connectivity's passive product portfolio. It is specifically categorized as a ferrite bead intended for electromagnetic interference suppression in modern electronics. The BMC-Q series designation indicates its specific construction and performance characteristics tailored for consumer and industrial applications.
Replacement Considerations
MLG0603P0N7CT000 by TDK is listed as a similar alternative for related Sigma Inductors parts, though direct substitution requires verification of impedance and current specs.
