BNX024H01B

Overview

The Murata Electronics BNX024H01B is a block-type LC EMI network filter array designed for surface-mount applications. It features a 5th-order low-pass circuit configuration with two channels, each providing a capacitance of 4.7 µF and rated for a continuous current of 20 A at a voltage rating of 50 V. The component utilizes a 4-SMD, no-lead package measuring 12.1 mm in length, 9.1 mm in width, and 3.5 mm in height. It offers an insertion loss of 35 dB within the frequency range of 100 kHz to 1 GHz. The device operates reliably between -55°C and +125°C and holds AEC-Q200 qualification.

Feature Summary

• High-current handling capability of 20 A per channel for robust power line filtering
• Compact block-type SMD construction suitable for space-constrained PCB layouts
• AEC-Q200 qualified for automotive reliability standards
• Wide operating temperature range from -55°C to +125°C

Applications

• Automotive power distribution units
• On-board charger (OBC) input filtering
• DC-DC converter output stages
• Electric vehicle traction inverter circuits

Procurement Notes

Verify the specific suffix against official Murata documentation to confirm exact electrical tolerances and packaging variations. Ensure the selected variant matches the required lead-free status and RoHS compliance for your assembly process. Cross-reference the AEC-Q200 certification details directly with the manufacturer's quality declarations to validate automotive suitability.

Selection Notes

Select this component when high current capacity and compact footprint are critical constraints. The 4.7 µF capacitance provides effective low-frequency noise attenuation. Consider the 3.5 mm height profile for board clearance requirements. Verify that the 20 A rating aligns with peak load conditions to prevent thermal degradation during operation.

Part Context

This part belongs to the Murata EMIFIL BNX series, which specializes in high-current EMI suppression filters. The series is engineered for demanding environments where standard filters fail due to saturation or size limitations. The BNX024H01B represents a specific configuration within this family, optimized for dual-channel power line protection in modern electronic systems.

Replacement Considerations

BNX024H01L is a documented alternative within the same series offering identical electrical characteristics but potentially different packaging options.
