RG1986-1

Overview

The Electrocube RG1986-1 is a single-phase RC network component designed for low-pass filtering applications. It features a capacitance of 0.5 microfarads with a tolerance of ±10% and an equivalent series resistance of 22 ohms at 10%. The device is rated for 250VAC or 600VDC continuous operation, with a maximum pulse peak voltage of 900VDC. Power dissipation is rated at 1/2 watt. The unit operates within a temperature range of -40°C to +80°C and utilizes radial leads.

Feature Summary

• Single-phase RC network configuration for low-pass filtering
• High pulse voltage withstand capability up to 900VDC
• Radial leaded construction for through-hole mounting

Applications

• Industrial automation control circuits
• Low-pass noise filtering in power supplies
• EMI/RFI suppression networks

Procurement Notes

Verify the specific suffix designation when ordering, as variations such as RG1986-1 may exist alongside other ratings like RG1986-8. Confirm that the required resistance value matches the 22-ohm specification, as some sources indicate different values for similar part numbers. Ensure the application voltage does not exceed the 600VDC limit. Check lead length requirements against the standard 3-inch specification provided by distributors.

Selection Notes

Select this component when a fixed 0.5 microfarad capacitance with integrated 22-ohm resistance is required for single-phase AC or DC line filtering. It is suitable for environments requiring operation between -40°C and +80°C. Consider the physical dimensions of 1.250 inches in length when designing PCB layouts or panel mounts. Verify compatibility with the target circuit's impedance characteristics before integration.

Part Context

The RG1986 series consists of resistor-capacitor networks manufactured by Electrocube, now part of AAR Electronics. These components are typically used in industrial settings for signal conditioning and power line filtering. The RG1986-1 specifically denotes the variant with 0.5 microfarad capacitance and 22-ohm resistance, distinguishing it from other series members with different electrical values.

Replacement Considerations

Cross-reference with RG1986-8 if a 220-ohm resistance value is acceptable instead of 22 ohms. Verify that any substitute maintains the 0.5 microfarad capacitance and 600VDC rating. Ensure the replacement supports the same radial package style and operating temperature range.
