RG1781-1

Overview

The Electrocube RG1781-1 is a single-phase RC EMI/RFI filter network designed for printed circuit board mounting. It features a capacitance of 1.0 µF with ±10% tolerance and a resistance of 33 Ohms. The component supports a rated voltage of 125V and withstands a peak pulse voltage of 300V. Physical dimensions include a length of 1.00 inches, width of 0.50 inches, and height of 0.75 inches. Lead wires are specified as #20 AWG tinned solid wire.

Feature Summary

• Single-phase RC low-pass filter configuration for noise suppression
• Compact radial package design facilitating side-by-side PCB mounting
• High surge capability with 300V peak pulse voltage rating

Applications

• Electromagnetic interference filtering in single-phase AC circuits
• Radio frequency interference suppression in electronic equipment
• Power line noise reduction for sensitive control systems

Procurement Notes

Verify the specific suffix or variant against the official Electrocube datasheet to ensure compatibility with your circuit requirements. Confirm that the 33 Ohm resistance and 1.0 µF capacitance values match your design specifications. Check lead wire gauge and length availability if custom termination is required. Ensure the 125V rated voltage meets your system's operating conditions.

Selection Notes

Select this component when a compact, single-stage RC filter is needed for single-phase applications. The 33 Ohm resistor value provides specific impedance characteristics suitable for general EMI suppression. Consider the physical footprint of 1.00 x 0.50 x 0.75 inches for board space constraints. The high peak pulse rating makes it suitable for environments with transient voltage spikes.

Part Context

The RG1781 series represents Electrocube's range of PC mount RC networks. These components are engineered for efficient noise filtration in power and signal lines. The RG1781-1 specifically denotes the variant with 33 Ohm resistance and 1.0 µF capacitance within this product family.

Replacement Considerations

Cross-reference with other RG1781 variants such as RG1781-2 or RG1781-6 if different resistance or capacitance values are required. Verify that substitute components maintain the same radial package dimensions and lead wire specifications for mechanical compatibility.
