• Test and measurement instrument protection

Procurement Notes

Verify that the specific part number matches the required current rating of 4 A and capacitance of 2.2 nF. Confirm compliance requirements such as UL, CSA, or EN certifications are necessary for the target market. Ensure the chassis mounting style and quick connect termination type align with the system design specifications before procurement.

Selection Notes

Select this model when a compact, single-phase solution is needed for moderate current applications up to 4 A. The dual-stage design offers superior performance compared to single-stage alternatives. Verify that the physical dimensions and mounting hardware fit the available chassis space. Ensure the operating voltage does not exceed the 250 VAC rating.

Part Context

This component belongs to the RP225 series of high-performance power line filters. The series includes various ratings for current and capacitance, distinguished by numerical codes in the model name. The RP225 series is engineered for demanding environments requiring reliable electromagnetic interference reduction in AC power lines.

Replacement Considerations

Direct substitutes within the same series include models with identical mounting styles but different current or capacitance ratings, such as RP225-3-2.2-QD or RP225-6-2.2-QD. Cross-series replacements require verification of physical footprint and electrical characteristics against the original design constraints.
