DSS1NB32A330Q91A

Overview

The Murata DSS1NB32A330Q91A is a third-order LC T-type EMI low-pass filter designed for single-channel noise suppression. It features a capacitance value of 33pF and supports a maximum current of 6 A with a rated voltage of 100 V DC. The component utilizes radial three-lead through-hole mounting, measuring 8.5 mm in length, 3.5 mm in width, and 7.5 mm in height. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Third-order LC T-type architecture for enhanced high-frequency noise attenuation
• Single-channel design optimized for targeted signal line filtering
• Robust construction supporting continuous currents up to 6 A

Applications

• High-speed digital interface noise suppression
• Power supply line EMI filtering
• Signal integrity enhancement in sensitive electronic circuits

Procurement Notes

Verify the specific capacitance value of 33pF against circuit requirements, as this differs from other variants in the DSS1NB3 series which may offer higher capacitance values. Confirm that the 6 A current rating and 100 V DC voltage rating align with the operational parameters of the target application to ensure reliable performance under load conditions.

Selection Notes

Select this component when a compact, third-order low-pass filter is required for single-channel applications. The radial three-lead package facilitates easy through-hole integration into PCB layouts where space constraints allow for the specified dimensions. Ensure the operating environment remains within the -40°C to +85°C temperature range for optimal functionality.
