MG2029-222Y

Overview

The MG2029-222Y is a high impedance ferrite chip bead manufactured by Bourns Inc. It features an SMD/SMT termination type and is housed in an 0805 (2012 metric) package with dimensions of 2 mm length, 1.2 mm width, and 0.9 mm height. The component provides an impedance of 2.2 kOhms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 2 A and has a maximum DC resistance of 100 mOhms. The operating temperature range spans from -55 C to +125 C.

Feature Summary

• High impedance performance for effective noise suppression
• Compact surface mount design suitable for space-constrained layouts
• Capable of handling high DC current loads

Applications

• Noise filtering in high-speed digital circuits
• EMI suppression in portable electronic devices
• Signal integrity enhancement in communication modules

Procurement Notes

Verify the specific suffix Y against the official Bourns datasheet to confirm exact impedance and tolerance specifications. Ensure the ordering quantity aligns with factory pack quantities or cut tape availability. Confirm RoHS3 compliance status if required by your manufacturing standards. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when high impedance attenuation is required at 100 MHz within an 0805 footprint. The 2 A current rating makes it suitable for power lines or high-current signal paths where noise reduction is critical. Compare its impedance profile against lower impedance variants in the MH/MG series to ensure adequate filtering without excessive signal loss.

Part Context

This part belongs to the Bourns MG series of high impedance ferrite beads. It shares the same physical 0805 package dimensions as other members like the MH2029 series but offers significantly higher impedance values. The series is designed for general-purpose EMI suppression in consumer and industrial electronics requiring compact noise control solutions.

Replacement Considerations

Direct substitutes include other 0805 ferrite beads with similar 2.2 kOhm impedance at 100 MHz. Verify that replacement parts match the 2 A current rating and 100 mOhms DCR limits. Check mechanical compatibility and thermal characteristics before integration.
