DSS1NB32A332Q91A

Overview

The Murata DSS1NB32A332Q91A is a three-terminal feed-through capacitor from the DSS series, designed for EMI/RFI suppression. It features a capacitance of 3300 pF (3.3 nF) with a tolerance of ±10%. The component supports a DC voltage rating of 100 V and handles a maximum current of 6 A. Operating temperatures range from -40°C to +85°C. Physical dimensions are 8.5 mm length, 7.5 mm height, and 3.5 mm width, utilizing radial leads for through-hole mounting.

Feature Summary

• Three-terminal feed-through architecture provides low inductance for effective high-frequency noise attenuation.
• Compact lead-type design enables mounting on standard 2.54 mm pitch layouts.
• High current handling capability suitable for power line filtering applications.

Applications

• EMI suppression in automotive electronic control units
• Noise filtering in industrial power supply circuits
• Signal integrity protection in sensitive measurement equipment

Procurement Notes

Verify the specific suffix Q91A against official Murata documentation to confirm packaging and terminal specifications. Ensure the operating environment remains within the -40°C to +85°C thermal limits. Confirm that the 6 A current rating aligns with the circuit requirements. Check for end-of-life status or alternative recommendations if sourcing for new designs.

Selection Notes

Select this component when low parasitic inductance is critical for EMI performance. The three-terminal design offers superior shielding compared to standard two-terminal capacitors. Ensure the PCB layout allows for proper grounding of the outer terminal to maximize filtering effectiveness. Verify space constraints fit the 8.5 x 7.5 x 3.5 mm footprint.

Part Context

This part belongs to the Murata DSS series of compact, high-performance lead-type three-terminal capacitors. The series is engineered for applications requiring efficient EMI/RFI suppression in limited spaces. These components utilize feed-through technology to provide attenuation across a broad frequency spectrum, making them suitable for both power and signal lines.

Replacement Considerations

Consult official Murata documentation for direct substitutes. Cross-reference electrical parameters such as capacitance, voltage rating, and current handling before considering alternatives from other manufacturers.
