MH3261-700Y

Overview

The MH3261-700Y is a high-current ferrite chip bead from the Bourns MH series, designed for surface-mount applications in a 1206 (3216 metric) package. It provides an impedance of 70 ohms with a 25% tolerance at a test frequency of 100 MHz. The component supports a maximum DC current rating of 4 amperes and features a maximum DC resistance of 30 milliohms. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• High current capability suitable for power delivery lines
• Low DC resistance minimizes power loss and heat generation
• Compact 1206 footprint enables dense circuit board layouts

Applications

• Power supply filtering
• Battery charger circuits
• Portable electronic devices
• Energy-efficient systems

Procurement Notes

Verify the lifecycle status before procurement as this specific part number may be obsolete or discontinued. Confirm that the 1206 package dimensions and electrical parameters align with the design requirements. Ensure compatibility with standard SMD/SMT assembly processes. Check for valid RoHS compliance documentation if required by the target market regulations.

Selection Notes

Select this component when a low impedance value of 70 ohms is required for EMI suppression on high-current lines. The 4A current rating makes it suitable for main power rails where lower resistance is critical. Compare against the MG series if higher impedance is needed, or the MU series for different current characteristics. Ensure the operating temperature range meets the environmental conditions of the final application.

Part Context

This component belongs to the Bourns MH series of high-current chip ferrite beads. The series is characterized by its ability to handle significant DC currents while providing effective noise filtration. The MH3261-700Y specifically targets applications requiring low insertion loss and robust performance in compact form factors.
