Procurement Notes

Verify the specific ordering suffix to confirm terminal type and capacitance values, as variations exist within the series. Ensure the selected variant matches the required current and voltage ratings for the target application. Cross-reference the manufacturer datasheet for precise dimensional tolerances and compliance documentation before finalizing procurement specifications.

Selection Notes

Select this model when space constraints require a compact form factor alongside moderate current handling capabilities. The quick connect interface facilitates rapid assembly in controlled environments. Verify that the 20 A rating aligns with peak load requirements and that the 4.7 nF capacitance meets leakage current standards for the specific equipment class.

Part Context

This component belongs to the RP105 series of power line filters from Astrodyne TDI. The series offers various configurations tailored for different current and capacitance needs while maintaining a consistent compact footprint. The RP105 series is engineered for applications requiring reliable electromagnetic interference suppression in single-phase AC power circuits.

Replacement Considerations

Direct substitutes include the RP105-20-4.7-QD, which shares identical electrical ratings but uses quick disconnect terminals instead of wire leads. Other RP105 variants may serve as alternatives if current or capacitance adjustments are permissible within the system design parameters.
