Overview
The DSS1ZB32A470Q91A is a feedthrough capacitor from the Murata EMIFIL DSS series. It features a capacitance of 47 pF with a DC voltage rating of 100 V and a tolerance of ±20%. Designed for radial through-hole mounting, it operates within a temperature range of -25°C to +85°C. The component has a current rating of 7 A and utilizes a Q55B package style.
Feature Summary
- Three-terminal construction integrating a built-in bead for enhanced high-frequency noise suppression
- Radial lead configuration optimized for panel or chassis mounting applications
- High current handling capability suitable for power line filtering requirements
Applications
- Electromagnetic interference (EMI) filtering in electronic equipment
- Power supply input/output noise suppression
- Signal line protection against radio frequency interference
Procurement Notes
Verify the specific suffix Q91A to confirm the exact package dimensions and termination style required for your design. Confirm availability status as distribution channels may vary. Ensure the operating temperature range meets your environmental specifications before finalizing procurement decisions.
Selection Notes
Select this component when a compact three-terminal filter is needed for radial mounting. Compare the 47 pF value against circuit impedance requirements. Verify that the 100 V DC rating exceeds the maximum circuit voltage. Check mechanical constraints against the Q55B package dimensions.
Part Context
This part belongs to the Murata DSS series of disc-type feedthrough capacitors. These components are engineered for robust EMI/RFI suppression in industrial and automotive environments. The series offers various capacitance values and voltage ratings to suit different filtering needs.
Replacement Considerations
Consult official Murata documentation for direct cross-references. Evaluate alternative DSS series variants with similar capacitance and voltage ratings if this specific part number is unavailable.
