DSS1ZB32A223Q91A

Overview

The DSS1ZB32A223Q91A is a lead-type, three-terminal feed-through capacitor from the Murata DSS1 series. It features a capacitance of 0.022 µF with a ±10% tolerance and a rated DC voltage of 100 V. Designed for through-hole mounting, it supports a maximum current of 6 A and operates within a temperature range of -40°C to +85°C. The component utilizes a radial termination style and is housed in a Q55B package with dimensions of 8.5 mm length, 7.5 mm height, and 3.5 mm depth.

Feature Summary

• Three-terminal LC filter topology for effective EMI suppression
• Compact lead-type design suitable for 2.54 mm pitch mounting
• High current handling capability up to 6 A

Applications

• Automotive lighting systems
• Vehicle security and anti-theft devices
• On-board display units

Procurement Notes

Verify the specific ordering suffix carefully, as variations such as Q91A or Q55B may indicate different packaging formats like ammo packs. Confirm the status of the part number, as some listings indicate it is not recommended for new designs. Ensure compatibility with existing PCB layouts due to the specific radial lead configuration and physical dimensions provided in the datasheet.

Selection Notes

Select this component when low ESL performance is required for noise measurement or power decoupling in high-speed equipment. The three-terminal structure offers superior high-frequency characteristics compared to standard two-terminal capacitors. Consider the 100 V DC rating and 6 A current limit to ensure adequate headroom for the target circuit's electrical requirements.

Part Context

This component belongs to the DSS1 series, which comprises compact, high-performance lead-type capacitors. The series is engineered for applications requiring efficient electromagnetic interference filtering in space-constrained environments. Murata Electronics manufactures these components to meet stringent automotive and industrial standards for reliability and signal integrity.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify mechanical fit and electrical specifications against alternative DSS1 series variants if direct substitution is necessary.
