BNX005-11

Overview

The Murata Electronics BNX005-11 is a through-hole LC EMI suppression block designed for data line protection. It features a 5th-order low-pass configuration with two channels and four leads. The component supports a rated voltage of 50V and handles up to 15A current. It provides an attenuation value of 40dB within the frequency range of 1MHz to 1GHz. The physical dimensions are 12.00mm in length, 11.00mm in width, and 13.00mm in height. Operating temperatures range from -40°C to 85°C.

Feature Summary

• Provides high insertion loss across wide frequency ranges from 1MHz to 1GHz
• Effective suppression of impulse noise on data lines
• Two-channel design for simultaneous signal path filtering

Applications

• Data lines for mobile devices
• Digital AV equipment
• PC peripheral equipment
• Displays

Procurement Notes

Verify the specific ordering suffix and packaging type against official Murata documentation before procurement. Confirm that the through-hole package style matches the target PCB layout requirements. Ensure the 15A current rating and 50V voltage specifications align with the circuit design parameters. Check for any RoHS compliance declarations required by the end product regulations.

Selection Notes

Select this component when high attenuation is required for data lines in noisy environments. The 5th-order LC topology offers steep roll-off characteristics suitable for suppressing broadband interference. Consider the through-hole mounting requirement and the physical footprint constraints during the design phase. Verify compatibility with the operating temperature range of the final assembly environment.

Part Context

This part belongs to the EMIFIL® BNX series of EMI suppression blocks manufactured by Murata Electronics. These components are engineered specifically for protecting sensitive electronic circuits from electromagnetic interference. The BNX series utilizes LC filter technology to provide robust noise reduction while maintaining signal integrity in high-current applications.

Replacement Considerations

Consult official Murata documentation for confirmed substitute part numbers. Do not assume cross-compatibility with other EMI filter series without verifying electrical parameters and physical dimensions.
