MH3225-300Y

Overview

The MH3225-300Y is a surface-mount ferrite bead from the Bourns MH series, designed for high-current applications. It features a 1210 (3225 metric) package with dimensions of 3.2 mm length, 2.5 mm width, and 1.5 mm height. The component provides an impedance of 30 ohms at 100 MHz with a tolerance of 25%. It supports a maximum DC current of 1 A and has a maximum DC resistance of 200 milliohms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• High current handling capability suitable for power line filtering
• Compact 1210 surface mount footprint for space-constrained designs
• Wide operating temperature range ensuring reliability in harsh environments

Applications

• Power supply input and output filtering
• Voltage regulation circuit noise suppression
• Battery charger signal line protection

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's latest datasheet to confirm compliance details and packaging options. Ensure the selected reel quantity matches production requirements. Confirm RoHS status and lead-free certification directly with the supplier or official documentation before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring effective high-frequency noise attenuation alongside moderate current carrying capacity. The 30-ohm impedance value targets specific EMI suppression needs. Evaluate the 200-milliohm DC resistance impact on voltage drop within the target power rail. Consider the 1210 package size relative to available PCB real estate and thermal management constraints.

Part Context
