Overview
The Murata DSS1NB32A680Q91A is a third-order LC T-type EMI filter designed for through-hole mounting. It features a capacitance value of 68pF and a rated voltage of 100V DC. The component supports a maximum current of 6 A and operates within a temperature range of -40°C to +85°C. Its physical dimensions are 8.50mm in length, 3.50mm in width, and 7.50mm in height. This radial three-lead device belongs to the EMIFIL DSS1 series.
Feature Summary
- Third-order LC T-type architecture for effective high-frequency noise suppression
- Compact radial three-lead design suitable for through-hole PCB mounting
- Rated for 100V DC with 6A current handling capability
Applications
- General-purpose EMI/RFI filtering in electronic circuits
- Signal integrity improvement in low-capacitance applications
- Power line noise reduction in compact electronic assemblies
Procurement Notes
Verify the specific capacitance value against project requirements, as datasheet variations exist for this series. Confirm availability status, as some distributors list this part as Not Recommended for New Designs (NRND). Ensure the through-hole radial package fits the target PCB layout constraints before finalizing procurement decisions.
Selection Notes
Select this component when a third-order low-pass filter response is required for signals with low capacitance sensitivity. The 68pF value distinguishes it from higher capacitance variants in the DSS1NB3 series. Consider the 6A current rating and 100V DC voltage limit to ensure compatibility with the circuit's electrical operating conditions and thermal environment.
Part Context
This component is part of the Murata EMIFIL DSS1 series, which offers compact lead-type three-terminal capacitors. The series is engineered for high-performance EMI suppression in space-constrained applications. The DSS1NB3 variant specifically utilizes an LC T-type topology to provide superior attenuation characteristics compared to standard single-capacitor feedthrough designs.
Replacement Considerations
Check for direct substitutes within the DSS1NB3 series with different capacitance values if 68pF is unavailable. Verify that any replacement maintains the same radial three-lead package and 100V DC rating to ensure mechanical and electrical compatibility.
