BNX026H01L

Overview

The Murata BNX026H01L is a surface-mount EMI suppression filter from the EMIFIL BNX series, rated for 50 VDC and 15 A. It features a second-order LC circuit topology with a 10 μF capacitance value. The component provides a minimum insertion loss of 35 dB across the 50 kHz to 1 GHz frequency range. Key electrical specifications include a maximum voltage drop of 45 mV and an insulation resistance of 10 MΩ. Designed for automotive electronics, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective electromagnetic interference and radio frequency interference suppression through low-pass filtering characteristics.
• Engineered for high-current applications with a robust 15 A rating and minimal voltage drop.
• Features a compact surface-mount design suitable for automated assembly processes.

Applications

• Automotive electronics systems
• Entertainment equipment
• Digital AV devices

Procurement Notes

Verify the specific suffix 'L' against official Murata documentation to confirm package and tape/reel specifications. Ensure the selected variant matches the required 50 VDC rating and 15 A current capacity for the target application. Cross-reference the datasheet for precise mechanical dimensions and soldering profile requirements before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high-current EMI filtering in automotive or digital AV environments. The 10 μF capacitance and second-order topology offer significant attenuation above 50 kHz. Consider the 12.1 mm x 9.1 mm footprint and 3.5 mm height constraints during PCB layout planning to ensure adequate clearance and thermal management.

Part Context

This part belongs to the Murata EMIFIL BNX series, which specializes in power line filters for automotive and industrial applications. The series is characterized by high current handling capabilities and compact surface-mount packaging. These filters are designed to meet stringent automotive reliability standards while providing efficient noise suppression for sensitive electronic loads.

Replacement Considerations

BNX025H01B is a verified substitute within the same series offering similar 15 A performance but rated for 25 VDC. Verify that the lower voltage rating of the alternative does not compromise system safety margins before implementation.
