RG1780-8

Overview

The Electrocube RG1780-8 is a single-phase RC EMI filter designed for through-hole mounting. It features a capacitance of 0.5 µF, a resistance of 220 Ohms, and a voltage rating of 200 VDC (125 VAC). The component operates within a temperature range of -40°C to 80°C. Its physical dimensions are 1.000" L x 0.380" W x 0.660" H. This first-order low-pass network provides effective suppression of electromagnetic interference in electronic circuits.

Feature Summary

• Integrates resistor and capacitor into a compact radial case for space-efficient side-by-side PCB mounting
• Provides first-order low-pass filtering to attenuate high-frequency noise
• Designed for reliable operation across a wide industrial temperature range

Applications

• Electromagnetic interference suppression in electronic equipment
• Power supply input filtering for single-phase AC/DC conversion
• Industrial control panel noise reduction

Procurement Notes

Verify the specific suffix or variant against official Electrocube documentation to ensure compatibility with your circuit requirements. Confirm that the 220 Ohm resistance and 0.5 µF capacitance values match your design specifications. Check the voltage ratings (200 VDC/125 VAC) against your system's operating conditions. Ensure the through-hole radial package fits your printed circuit board layout constraints before ordering.

Selection Notes

Select this component when a fixed-value RC network is required for single-channel EMI filtering. It is suitable for applications needing a compact solution for first-order attenuation. Consider the thermal limits (-40°C to 80°C) and power dissipation capabilities relative to your environment. Verify that the through-hole mounting style aligns with your assembly process and board design.

Part Context
