Procurement Notes

Verify the specific suffix against official Murata documentation to confirm pinout and electrical characteristics. Ensure the selected variant matches the required current rating and package dimensions for the target PCB layout. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and lead times.

Selection Notes

Select this component for applications requiring robust EMI suppression in compact spaces. The 5th-order design offers steep attenuation characteristics suitable for sensitive high-speed data lines. Consider the 10A current rating and 50V voltage limit when designing power or signal paths. Verify thermal management requirements given the operating temperature range.

Part Context

This component belongs to the Murata EMIFIL BNX series, which specializes in EMI network filters. These filters are engineered to suppress electromagnetic interference in electronic circuits. The BNX series is known for supporting high currents while maintaining a small footprint, making it suitable for modern portable and industrial electronics.

Replacement Considerations

Check for direct substitutes such as the BNX022-01L or BNX022-01D from Murata. Verify that alternative parts match the 50V rating, 10A current capacity, and SMD package dimensions. Ensure the replacement maintains the 5th-order low-pass characteristic and frequency response up to 1GHz.
