DSS1NB32A103Q93A

Overview

The Murata DSS1NB32A103Q93A is a three-terminal feedthrough capacitor belonging to the DSS series. It features a capacitance of 0.01 µF with a tolerance of ±30%. The component is rated for a maximum DC voltage of 100 V and supports a continuous current of 6 A. Designed for through-hole radial mounting, it operates within a temperature range of -40°C to +85°C. This device functions as an EMI filter, providing low-pass noise suppression for electronic circuits.

Feature Summary

• Integrates a built-in bead structure to enhance high-frequency attenuation performance
• Utilizes a three-terminal design to minimize parasitic inductance for effective filtering
• Constructed for robust through-hole installation on printed circuit boards

Applications

• General-purpose electromagnetic interference (EMI) noise suppression
• Low-pass filtering in power supply input stages
• Signal integrity protection in sensitive electronic assemblies

Procurement Notes

Verify the specific suffix Q93A against official Murata documentation to confirm packaging and compliance details. Confirm availability status as distributors may list this part as Not Recommended for New Designs (NRND). Ensure the selected variant matches the required capacitance tolerance and current rating for the target application before finalizing procurement orders.

Selection Notes

Select this component when a compact, high-current EMI filter is required for through-hole applications. The 6 A rating suits moderate power lines, while the 100 V DC rating defines the voltage boundary. Compare against the broader DSS1NB3 series if different capacitance values or termination styles are needed. Validate that the thermal operating range meets the environmental constraints of the final assembly.

Part Context

This component is part of the Murata EMIFIL DSS series, which specializes in three-terminal feedthrough capacitors. These devices are engineered to provide superior high-frequency noise suppression compared to standard two-terminal capacitors by minimizing lead inductance. The series is widely recognized for its reliability in industrial and consumer electronics requiring strict EMI control.

Replacement Considerations

Public sources indicate this specific part number is Not Recommended for New Designs (NRND). Engineers should consult the official Murata datasheet for the current recommended alternative within the DSS1NB3 series or equivalent three-terminal feedthrough capacitors from other manufacturers that match the electrical specifications.
