DSS1ZB32A121Q91A

Overview

The Murata DSS1ZB32A121Q91A is a feed-through capacitor belonging to the EMIFIL DSS series. It features a capacitance of 120 pF with a ±10% tolerance and a rated DC voltage of 100 V. Designed for through-hole mounting, it utilizes a radial three-lead configuration within a Q55B package measuring 8.5 mm in length, 7.5 mm in height, and 3.5 mm in depth. The component supports a maximum current of 6 A and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Provides effective electromagnetic interference suppression using LC(T) filter topology.
• Offers robust mechanical stability through a rigid metal case construction suitable for high-current applications.
• Ensures low impedance grounding via the central pin design inherent to feed-through capacitor architecture.

Applications

• Power supply input filtering
• High-frequency noise suppression in electronic circuits
• EMI mitigation in industrial control systems

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before initiating procurement. Confirm availability constraints as distribution channels may restrict sales in specific regions. Ensure that existing inventory sources are authorized to prevent counterfeit risks during replacement sourcing.

Selection Notes

Select this component when a compact, high-current feed-through solution is required for EMI filtering. The 100 V rating and 6 A current capacity define its operational limits. Verify that the physical dimensions fit the target PCB layout and that the 120 pF capacitance aligns with the specific frequency attenuation requirements.

Part Context

This part belongs to the Murata EMIFIL DSS series of feed-through capacitors. These components are engineered for high-performance EMI suppression in environments requiring reliable thermal and electrical stability. The series is characterized by its metal case construction and through-hole mounting style, distinguishing it from surface-mount alternatives.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative sourcing should prioritize verified distributors or equivalent Murata series components with matching electrical and mechanical specifications.
