DSS1NB32A271Q55B

Overview

The Murata DSS1NB32A271Q55B is a three-terminal feedthrough capacitor with a capacitance of 270 pF and a DC voltage rating of 100 V. It features a radial through-hole mounting style and a tolerance of ±10%. The component supports a maximum current of 6 A and operates within a temperature range of -40°C to +85°C. It belongs to the DSS1 series and utilizes a Q55B package configuration.

Feature Summary

• Provides effective EMI/RFI suppression via a T-type LC filter structure
• Integrates a built-in bead for enhanced high-frequency noise attenuation
• Offers low impedance path for common-mode noise reduction

Applications

• Power supply input filtering
• Signal line noise suppression in electronic equipment
• EMI mitigation in industrial control systems

Procurement Notes

Verify the specific suffix Q55B against official Murata documentation to confirm package dimensions and terminal configuration. Ensure the selected variant matches the required 6 A current rating and 100 V DC withstand voltage for the target circuit design. Cross-reference the lead time and availability status directly with authorized distributors or the manufacturer, as stock levels fluctuate.

Selection Notes

Select this component when a compact, three-terminal feedthrough solution is required for high-frequency noise filtering in through-hole assemblies. The 270 pF value suits applications needing precise capacitance with tight tolerance. Consider the 6 A current handling capability and the operating temperature range to ensure compatibility with the thermal environment of the final assembly.

Part Context

This part belongs to the Murata EMIFIL DSS1 series of feedthrough capacitors. These components are designed for use in environments requiring robust electromagnetic interference suppression. The series offers various capacitance values and package options to suit different power and signal line requirements.

Replacement Considerations

Check for direct substitutes within the DSS1 series with identical electrical parameters. Verify mechanical fit and terminal alignment before replacing. Consult Murata's official obsolescence notices for discontinuation status.
