DSS1NB32A151Q91A

Overview

The Murata DSS1NB32A151Q91A is a three-terminal feedthrough capacitor belonging to the EMIFIL DSS1 series. It features a capacitance of 150 pF with a tolerance of ±10% and a rated DC voltage of 100V. Designed for through-hole mounting, this radial component utilizes an LC (T-type) third-order low-pass filter topology. It supports a maximum current rating of 6 A and operates within a temperature range of -40°C to +85°C. The physical dimensions are 8.50 mm in length, 3.50 mm in width, and 7.50 mm in height.

Feature Summary

• Provides effective electromagnetic interference suppression using a third-order LC T-type low-pass filter architecture.
• Features a robust three-terminal design that ensures low parasitic inductance for high-frequency noise attenuation.
• Capable of handling continuous currents up to 6 A while maintaining stable performance across a wide industrial temperature range.

Applications

• General-purpose EMI/RFI filtering in electronic circuits
• Power supply input stages requiring noise reduction
• Signal lines needing high-frequency interference suppression

Procurement Notes

Verify the specific suffix Q91A against official Murata documentation to confirm packaging details and compliance status. Ensure the selected variant matches the required capacitance value of 150 pF and voltage rating. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a compact, high-current feedthrough capacitor is required for through-hole assembly. The 150 pF value suits applications targeting higher frequency noise attenuation compared to larger capacitance variants. Consider the 6 A current rating and 100 V DC voltage limit to ensure compatibility with the circuit's electrical requirements and thermal environment.
