DSS1ZB32A472Q91A

Overview

The DSS1ZB32A472Q91A is a feedthrough capacitor from the Murata EMIFIL DSS series. It features a capacitance of 4700 pF (4.7 nF) with a tolerance of ±10%. The component has a DC voltage rating of 100 V and supports a maximum current of 6 A. It utilizes radial termination for through-hole mounting in a Q55B package. Physical dimensions are 8.5 mm length, 7.5 mm height, and 3.5 mm depth. The operating temperature range spans from -40°C to +85°C. The unit weighs 450 mg and is supplied in an Ammo Pack.

Feature Summary

• Provides EMI/RFI filtering via three-terminal feedthrough architecture
• Supports high current handling up to 6 A
• Enables compact through-hole mounting on standard 2.54 mm pitch

Applications

• High-frequency noise suppression in electronic circuits
• Power line filtering for sensitive equipment
• EMI mitigation in communication systems

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before initiating procurement. Confirm that the Ammo Pack packaging aligns with assembly requirements. Ensure the Q55B radial lead configuration matches the target PCB footprint. Validate RoHS compliance documentation against specific project standards prior to ordering.

Selection Notes

Select this component when a 4.7 nF capacitance value is required for high-current applications. The 100 V DC rating suits low-voltage power distribution networks. The through-hole format provides mechanical stability compared to surface-mount alternatives. Verify thermal limits against the maximum ambient temperature of the intended environment.
