RG1986-2

Overview

The Electrocube RG1986-2 is a single-phase RC snubber network designed for surge suppression and EMI/RFI filtering. It features a capacitance of 0.5 microfarads with a tolerance of ±10 percent, paired with a resistance of 33 ohms. The component is rated for an operating voltage of 600 volts DC and 250 volts AC, with a maximum peak pulse voltage of 900 volts. Power dissipation is rated at 0.5 watts. The unit utilizes radial leads for mounting.

Feature Summary

• Single-phase RC network configuration for transient suppression
• Compact design suitable for free-hanging installation across coils or contacts
• Radial leaded construction for easy integration into electrical circuits

Applications

• Surge suppression in single-phase electrical systems
• EMI and RFI filtering for low-pass signal conditioning
• Protection of contactors and relays from voltage transients

Procurement Notes

Verify the specific suffix code against official Electrocube documentation to confirm exact electrical tolerances and lead lengths. Ensure the selected variant matches the required voltage rating of 600V DC and 250V AC for your application. Cross-reference datasheets to confirm physical dimensions and thermal characteristics before finalizing procurement decisions.

Selection Notes

Select this component when a robust single-phase RC snubber is required for inductive load protection. The 33-ohm resistor and 0.5-microfarad capacitor combination offers specific damping characteristics suitable for standard industrial control voltages. Consider the 0.5-watt power rating and temperature range limits during circuit design to ensure reliable operation under continuous duty cycles.

Part Context

The RG1986 series represents Electrocube's line of MTW-leaded single-phase RC networks. These components are engineered for compact mounting directly across switching elements. The RG1986-2 specifically denotes the 33-ohm resistance variant within this family, distinguishing it from other models like the RG1986-8 which features different resistance values.

Replacement Considerations

Direct substitutes include the RG1986-1 and RG1986-3, though these possess different resistance values (47 ohms and 68 ohms respectively). Verify that any replacement maintains the 0.5 microfarad capacitance and 600V DC rating to ensure equivalent circuit performance without altering the time constant significantly.
