BNX003-11

Overview

The Murata BNX003-11 is a block-type EMI filter circuit designed for through-hole mounting. It features a voltage rating of 150 V and a current rating of 10 A. The component operates within a temperature range of -40°C to +85°C. It provides high insertion loss across wide frequency ranges from 1 MHz to 1 GHz, making it effective against impulse noise.

Feature Summary

• Incorporates through-type capacitors, monolithic chip capacitors, and beads within a single block structure
• Delivers high insertion loss in wide frequency ranges from 1 MHz to 1 GHz
• Effective suppression of impulse noise

Applications

• General electronic equipment requiring EMI/RFI filtering
• Power supply input stages
• Industrial control systems

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may be hosted by distributors. Confirm that the part number BNX003-11 corresponds to the 150V 10A through-hole specification. Ensure compatibility with existing PCB hole patterns and thermal requirements before finalizing procurement.

Selection Notes

Select this component when high current handling (10 A) and broad-spectrum noise suppression are required in a through-hole configuration. The block design integrates multiple passive elements, simplifying layout compared to discrete components. Verify that the 150 V rating exceeds the maximum circuit voltage under all operating conditions.

Part Context

This component belongs to the Murata BNX series of block-type EMIFIL filters. These circuits combine various internal technologies to provide robust electromagnetic interference protection. The series is characterized by its ability to handle significant current loads while maintaining compact physical dimensions relative to discrete solutions.

Replacement Considerations

Direct substitutes must match the 150 V, 10 A, and through-hole specifications. Verify that alternative parts offer comparable insertion loss characteristics between 1 MHz and 1 GHz. Ensure physical footprint compatibility with the original mounting holes.
