DSS1NB31H473Q91A

Overview

The Murata DSS1NB31H473Q91A is a third-order LC (T-Type) EMI filter designed for through-hole mounting. It features a capacitance of 0.047µF and supports a maximum current of 6 A with a rated voltage of 50 V. The component utilizes a radial package with three leads, measuring 8.50 mm in length, 3.50 mm in width, and 7.50 mm in height. It operates within a temperature range of -40°C to 85°C and complies with RoHS3 standards.

Feature Summary

• Provides third-order low-pass filtering characteristics using an LC T-type topology.
• Designed for high-current applications with a 6 A rating.
• Utilizes a compact radial three-lead through-hole package.

Applications

• General-purpose EMI suppression
• Power line filtering
• Electronic equipment noise reduction

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, such as cut tape or tape and reel options. Confirm that the 50 V rating and 6 A current capacity align with the target circuit requirements. Check for end-of-life notifications or product change notices regarding manufacturing location or packaging updates before finalizing procurement plans.

Selection Notes

Select this component when a third-order attenuation profile is required for single-channel EMI suppression. Ensure the operating environment stays within the specified -40°C to 85°C temperature range. Verify that the physical dimensions fit the available board space and that the through-hole mounting method is compatible with the assembly process.

Part Context

This part belongs to the Murata EMIFIL® DSS1 series, which focuses on LC filters for electromagnetic interference suppression. The DSS1NB31H473Q91A specifically represents a variant within this family characterized by its 0.047µF capacitance and radial leaded construction, distinguishing it from other series members with different ratings or packages.

Replacement Considerations

Consult official Murata documentation for verified substitute part numbers. Cross-referencing requires matching the LC T-type topology, third-order specification, 0.047µF capacitance, 6 A current rating, and 50 V voltage rating to ensure functional equivalence.
