Procurement Notes

Verify the specific suffix 'ZB' against official documentation, as standard listings often reference the 'NB3' variant. Confirm the lifecycle status, as this part may be marked as Not Recommended for New Designs (NRND). Ensure compatibility with existing panel cutouts and lead configurations before finalizing procurement plans.

Selection Notes

Select this component when a low-inductance, high-current feedthrough solution is required for EMI suppression. The radial three-lead design facilitates direct chassis or panel mounting. Consider the 100V rating and 6A current capacity to ensure adequate margins for the target power line application.

Part Context

This component is part of the Murata DSS1 family of feedthrough capacitors. These components are engineered for noise reduction in sensitive electronic circuits. The DSS1NB3 series specifically targets automotive comfort and infotainment applications requiring reliable EMI/RFI filtering.

Replacement Considerations
