RG1986-8

Overview

The Electrocube RG1986-8 is a single-phase RC EMI/RFI filter network designed for through-hole mounting. It features a capacitance of 0.5 microfarads with a tolerance of ±10 percent and an equivalent series resistance of 220 ohms. The component is rated for 600 volts DC and 250 volts AC, with a maximum peak pulse voltage of 900 volts. Power dissipation is specified at 0.5 watts. It utilizes MTW wire leads, typically 6 inches in length with #18AWG gauge, allowing for free-hanging installation.

Feature Summary

• First-order low-pass filtering configuration for EMI suppression
• Compact design enabling easy free-hanging mounting across coils and contacts
• High voltage rating suitable for industrial power applications

Applications

• Suppression across motor coils
• Protection for contactor contacts
• General purpose EMI filtering in industrial automation

Procurement Notes

Verify the specific suffix (e.g., -8, -8-6) to confirm lead length and exact package dimensions, as these vary within the RG1986 family. Ensure the operating environment temperature falls within the -40°C to 80°C range. Confirm that the circuit voltage does not exceed the 600V DC or 250V AC ratings to prevent dielectric failure.

Selection Notes

Select this component when a robust, high-voltage RC snubber is required for inductive load protection. The 220-ohm resistor value provides effective damping for specific transient profiles. Consider the physical size and lead length requirements for free-hanging installation versus board-mounted alternatives. Verify compatibility with the target switching frequency and voltage spikes.

Part Context

This part belongs to the Electrocube RG Series of single-phase RC networks. These components are widely used in industrial control circuits to mitigate electromagnetic interference generated by switching inductive loads. The series offers various resistance and capacitance combinations tailored to different voltage and current ratings.

Replacement Considerations

Direct substitutes must match the 0.5µF capacitance, 220Ω resistance, and 600V DC rating. Check lead length and insulation type (MTW) for mechanical fit. Generic RC networks may lack the specific pulse voltage handling capability of 900V peak.
