Procurement Notes

Verify the specific suffix number against official Electrocube documentation to confirm exact R-C values and voltage ratings. Ensure the ordering part number matches the required impedance and capacitance specifications for your circuit design. Confirm package type and lead configuration align with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a fixed 47 Ohm resistor and 0.5 microfarad capacitor combination is required for low-pass filtering applications. Consider the physical dimensions and thermal operating range to ensure compatibility with the target enclosure and ambient conditions. Validate that the 250 VAC rating meets the system's electrical safety standards.

Part Context

This component belongs to the Electrocube RG1784 series of PC mount single-phase RC networks. The series offers various configurations with different resistance and capacitance values to suit diverse filtering needs. These components are engineered for reliability in industrial settings where compact size and effective noise reduction are critical.

Replacement Considerations

Cross-reference with other Electrocube RG1784 variants such as RG1784-1 or RG1784-5 if different R-C values are acceptable. Verify that substitute parts maintain identical voltage ratings and physical dimensions to ensure direct fitment without redesigning the PCB layout.
