MH4532-132Y

Overview

The Bourns MH4532-132Y is a high-current chip ferrite bead from the MH series, designed for surface-mount applications. It features an 1812 (4532 metric) package with dimensions of 4.5 mm length, 3.2 mm width, and 1.5 mm height. The component provides an impedance of 1.3 kOhms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 3 A and has a maximum DC resistance of 60 mOhms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• High current handling capability suitable for power line filtering
• Surface-mount design in a compact 1812 footprint
• Wide operating temperature range for diverse environmental conditions

Applications

• Power supply output filtering
• DC-DC converter noise suppression
• Signal line EMI reduction in high-current circuits

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's latest documentation to confirm packaging details and compliance status. Check for obsolescence notices as some sources indicate this part may be discontinued. Ensure the required impedance tolerance and current ratings align with the circuit design before ordering.

Selection Notes

Select this component when high current capacity is required alongside significant impedance at 100 MHz. The 1812 package offers a balance between current handling and board space. Compare the 60 mOhm DC resistance against voltage drop requirements in the application. Consider thermal performance within the specified -55°C to +125°C range.

Part Context

This ferrite bead belongs to Bourns' MH series, which focuses on high-current applications. The series utilizes specific ferrite materials optimized for power integrity. The MH4532 designation indicates the physical size and series family. These components are distinct from standard signal-line ferrites due to their ability to handle higher amperage without saturation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Consult the manufacturer's official replacement guide or datasheet for equivalent parts within the MH series or other high-current ferrite bead lines.
