• Single-channel low-pass filtering design

Applications

• General purpose EMI suppression
• Power line noise filtering
• Electronic equipment input stages

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Verification of availability should focus on surplus distributors or last-time buy options rather than standard production channels. Confirm exact suffix specifications against legacy documentation to ensure compatibility with existing designs.

Selection Notes

Select this part only if the specific 2200pF capacitance and 6 A rating align with system requirements. Due to its obsolete status, alternative components from the same series or newer generations must be evaluated for pinout and electrical equivalence before finalizing the design.

Part Context

Part of the EMIFIL DSS9 series, this filter provides robust electromagnetic interference suppression. It belongs to the broader category of passive LC filters manufactured by Murata Electronics, specifically engineered for through-hole mounting in industrial and commercial electronic assemblies requiring reliable noise reduction.

Replacement Considerations

DSS9NP32A222Q55B is a confirmed substitute within the same series offering identical electrical characteristics and form factor.
