DSS1NB32A271Q91A

Overview

The Murata DSS1NB32A271Q91A is a feedthrough capacitor from the EMIFIL DSS1 series. It features a capacitance of 270 pF with a tolerance of ±10%. The rated DC voltage is 100 V, and it supports a maximum current of 6 A. Designed for through-hole radial installation, it operates within a temperature range of -40°C to +85°C. The component has an insulation resistance of 50 MOhms and utilizes a Q55B package.

Feature Summary

• Provides low-pass filtering for EMI/RFI suppression in power lines
• Supports high continuous current handling up to 6 A
• Offers robust thermal stability across extended industrial temperature ranges

Applications

• General purpose EMI filtering in electronic circuits
• Power supply input stages requiring noise reduction
• Embedded systems with sensitive microcontroller components

Procurement Notes

Verify the specific capacitance value against design requirements, as datasheet variations exist between 270 pF and other values in similar suffixes. Confirm the operating temperature range aligns with environmental conditions. Ensure the radial through-hole mounting style fits the PCB layout constraints. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a compact feedthrough capacitor is needed for high-current applications. The 100 V rating suits low-voltage DC power lines. Consider the physical dimensions of the Q55B package for board space limitations. Compare against other DSS1 series variants if different capacitance or voltage ratings are required for the specific circuit topology.

Part Context

This part belongs to Murata's EMIFIL DSS1 series of feedthrough capacitors. These components are designed to suppress electromagnetic interference in power distribution networks. The series offers various capacitance values and voltage ratings to suit different filtering needs while maintaining a consistent form factor for easy integration into existing designs.

Replacement Considerations

Check for direct substitutes within the DSS1 series with matching 270 pF capacitance and 100 V rating. Verify that any replacement maintains the 6 A current rating and radial termination style. Ensure the replacement component meets the same -40°C to +85°C operating temperature range.
