MH4532-131Y

Overview

The Bourns MH4532-131Y is a high current chip ferrite bead from the MH series, designed for surface mount applications. It features an impedance of 130 Ohms with a tolerance of 25% at a test frequency of 100 MHz. The component supports a maximum DC current of 3 A and has a maximum DC resistance of 40 mOhms. Housed in an 1812 (4532 metric) package measuring 4.5 mm x 3.2 mm x 1.5 mm, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• High resistance to heat and humidity
• Resistance to mechanical shock and pressure
• Accurate dimensions for surface mount technology

Applications

• Electromagnetic interference (EMI) reduction in electronic circuits
• High current signal line filtering
• Power supply noise suppression

Procurement Notes

Verify the specific datasheet version for the MH4532-131Y to confirm RoHS compliance details and exact packaging options such as cut tape or reel quantities. Ensure that the 3 A current rating aligns with your circuit's thermal management capabilities, as self-heating may affect performance near the upper limit. Cross-reference the 130 Ohm impedance specification against your target noise frequency spectrum to validate effectiveness.

Selection Notes

Select this component when a 1812 footprint is required for high current handling up to 3 A. The 130 Ohm impedance value is suitable for suppressing noise in the hundreds of megahertz range. Consider the low DC resistance of 40 mOhms to minimize voltage drop in power lines. The wide operating temperature range ensures reliability in harsh environments where thermal stability is critical for EMI suppression performance.

Part Context

This part belongs to the Bourns MH Series of high current chip ferrite beads. These components are engineered to provide effective common mode noise suppression while maintaining structural integrity under mechanical stress. The series is characterized by its ability to handle significant DC currents without saturation, making it distinct from lower-current ferrite alternatives in similar form factors.

Replacement Considerations

Check for other parts in the MH series with compatible impedance and current ratings. Verify that any substitute maintains the 1812 package dimensions and meets the same thermal and humidity resistance specifications.
