BNX002-11

Overview

The Murata BNX002-11 is a block-type EMI filter designed for noise suppression in electronic circuits. It operates with a rated voltage of 50V DC and supports a maximum current of 10A. The component provides high insertion loss, reaching up to 40dB within the 1MHz to 1GHz frequency range. It features a five-stage low-pass filtering architecture integrating through-hole capacitors, monolithic capacitors, and ferrite beads. The unit measures approximately 12mm x 11mm x 13mm and utilizes a radial leaded installation method.

Feature Summary

• Integrates through-hole capacitors, monolithic capacitors, and ferrite beads into a single block structure
• Provides effective suppression for impulse noise including electrostatic discharge (ESD) and spike noise
• Delivers high insertion loss across wide frequency ranges from 1MHz to 1GHz
• Constructed without connecting wires to ensure high reliability

Applications

• Display equipment such as PDP and LCD TVs
• Digital AV equipment and entertainment devices
• PC peripherals and industrial equipment
• DC power circuit noise suppression

Procurement Notes

Verify the specific suffix against official Murata documentation to confirm exact physical dimensions and terminal configurations. Ensure the selected variant matches the required operating temperature range and current ratings for the target application environment.

Selection Notes

Select this component for applications requiring robust EMI/RFI suppression in DC power lines. Consider the 10A current rating and 50V voltage limit when designing power stages. The block type form factor is suitable for through-hole mounting where space allows for larger footprint components compared to surface mount alternatives.

Part Context

This part belongs to the Murata BNX series of block-type EMIFIL filters. These components are engineered to address electromagnetic interference issues by combining multiple passive elements. The series is widely used in consumer electronics and industrial systems to maintain signal integrity and comply with EMC standards.

Replacement Considerations

Consult official Murata substitution guides for verified equivalents. Cross-referencing with other BNX series variants may be necessary if dimensional constraints or specific impedance characteristics differ from the original design requirements.
