DSS1ZB32A221Q91A

Overview

The DSS1ZB32A221Q91A is a feed-through capacitor from the Murata EMIFIL DSS series. It features a capacitance of 220 pF and a rated voltage of 100 V DC. The component supports a maximum current of 6 A and operates within a temperature range of -40°C to +85°C. It utilizes a radial three-lead through-hole mounting style with Q55B package dimensions of 8.5 mm length, 7.5 mm height, and 3.5 mm width. The device functions as a third-order low-pass LC(T) filter for EMI suppression.

Feature Summary

• Provides effective electromagnetic interference suppression using a feed-through architecture
• Supports high continuous current handling capabilities for power line applications
• Offers robust thermal stability across a wide industrial operating temperature range

Applications

• General purpose EMI filtering in electronic circuits
• Power supply input stages requiring noise attenuation

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before initiating any new product development projects. Confirm availability constraints as distribution may be limited or discontinued in specific regions. Ensure that the radial lead configuration matches the target PCB footprint requirements. Validate compliance with relevant environmental directives such as RoHS standards prior to final procurement authorization.

Selection Notes

Select this component when a third-order low-pass LC(T) filter topology is required for single-channel EMI reduction. The 100 V DC rating and 6 A current capacity define the electrical boundaries for suitable circuit integration. Consider the physical dimensions and through-hole mounting method against available board space and assembly processes. Compare alternative capacitance values within the DSS series if different filtering characteristics are needed.
