MH4516-102Y

Overview

The MH4516-102Y is a high current chip ferrite bead manufactured by Bourns Inc. It features an SMD/SMT end type and utilizes the 1806 (4516 metric) package with dimensions of 4.5 mm length, 1.6 mm width, and 1.6 mm height. The component provides an impedance of 1000 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 1.5 A and has a maximum DC resistance of 150 mOhms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Designed for high current applications in power and signal line filtering
• Utilizes surface mount technology for automated assembly integration
• Constructed within a compact 1806 metric footprint

Applications

• Power supply output filtering
• Signal line noise suppression
• High current circuit protection

Procurement Notes

Verify the specific impedance value against the datasheet, as the model suffix '102' typically denotes 1000 Ohms, while some distributor listings may incorrectly reference other values like 60 Ohms associated with different series variants. Confirm the package dimensions and current rating match the design requirements before ordering. Ensure compliance with RoHS standards if required by the application specifications.

Selection Notes

Select this component when high current handling capability is required alongside significant impedance at 100 MHz. The low DC resistance minimizes voltage drop in power lines. Verify that the 1.5 A current rating meets the peak load requirements of the target circuit. Consider the thermal performance within the specified temperature range during operation.

Part Context

This part belongs to the MH series of high current chip ferrite beads from Bourns. These components are engineered to suppress electromagnetic interference in circuits carrying substantial direct current. The series offers various impedance options within the same physical footprint to accommodate different filtering needs without altering the board layout.

Replacement Considerations

Consult official Bourns documentation for verified substitute part numbers within the MH series or equivalent high-current ferrite bead families. Cross-referencing requires matching impedance, current rating, and package dimensions.
