BNX024H01L

Overview

The Murata BNX024H01L is a surface-mount LC EMI filter circuit from the EMIFIL BNX series. It features a low-pass topology with two channels and a fifth-order filtering structure. The component supports a rated voltage of 50V DC and handles a maximum current of 20A. It utilizes a 4-SMD, no-lead package measuring 12.10mm in length, 9.10mm in width, and 3.70mm in height. Key electrical parameters include a capacitance value of 4.7µF, an attenuation of 35dB within the 100kHz to 1GHz frequency range, and an operating temperature range of -55°C to +125°C.

Feature Summary

• Provides effective electromagnetic interference suppression through a fifth-order LC low-pass filter architecture designed for high-current applications.
• Features a compact surface-mount footprint with no leads, facilitating automated assembly and space-constrained board layouts.
• Engineered for automotive reliability, meeting AEC-Q200 qualification standards for durability under varying thermal conditions.

Applications

• Automotive electronics systems requiring robust EMI suppression
• High-current power distribution networks
• Digital audio/video equipment interfaces

Procurement Notes

Verify the specific suffix against official Murata documentation to confirm exact capacitance and current ratings, as variations exist within the BNX02xH01x family. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure packaging format matches production line capabilities, as options include tape and reel or cut tape. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability.

Selection Notes

Select this component when designing circuits that require high current handling capability alongside significant noise attenuation in the RF spectrum. The fifth-order design offers steep roll-off characteristics suitable for sensitive digital loads. Evaluate the physical dimensions against available PCB real estate, noting the 3.70mm height profile. Consider the thermal operating range if the application environment exceeds standard commercial limits.

Part Context

This component belongs to the Murata EMIFIL BNX series, which specializes in block-type EMI suppression filters for automotive and industrial markets. The series is characterized by its ability to handle high currents while maintaining small form factors. These filters are engineered to meet stringent automotive quality standards, ensuring long-term reliability in harsh operating environments compared to general-purpose consumer components.

Replacement Considerations

Consult official Murata substitution guides for verified alternatives. Generic equivalents may not match the specific fifth-order LC topology or AEC-Q200 automotive qualification required for this application.
