RG1988-8

Overview

The Electrocube RG1988-8 is a single-phase RC EMI filter designed for first-order low-pass noise suppression. It integrates a 220 Ohm resistor and a 0.25 µF capacitor within a compact radial component. The unit supports operation at 600 VDC or 250 VAC, providing effective attenuation for electromagnetic interference in electrical circuits. Its construction utilizes MTW leads, facilitating straightforward installation across coils and contacts without requiring complex mounting hardware.

Feature Summary

• Single-phase RC network configuration for first-order low-pass filtering
• Compact design enabling free-hanging mounting across components
• Radial leaded construction for direct circuit integration

Applications

• Noise suppression across electrical coils
• Interference mitigation across contact points
• EMI reduction in single-phase AC/DC circuits

Procurement Notes

Verify the specific voltage rating (600VDC/250VAC) and capacitance tolerance against the official datasheet before procurement. Confirm that the radial lead style matches the target PCB or terminal block requirements. Ensure the application environment does not exceed the specified thermal limits for the internal resistor and capacitor materials.

Selection Notes

Select this component when a simple, cost-effective first-order low-pass filter is required for single-phase applications. The fixed 220 Ohm resistance and 0.25 µF capacitance are optimized for general EMI suppression rather than precise tuning. Consider alternative values if the circuit demands different cutoff frequencies or higher current handling capabilities.

Part Context

This part belongs to the Electrocube RG1988 series of MTW leaded single-phase RC networks. The series offers various resistance and capacitance combinations to suit different filtering needs. The RG1988-8 specifically provides a balanced impedance profile suitable for standard industrial and commercial electronic equipment requiring basic noise reduction.

Replacement Considerations

Direct substitutes include other RG1988 series variants with similar RC values, such as RG1988-7 or RG1988-9, though their specific resistance and capacitance ratings differ. Verify compatibility with any generic single-phase RC filters having identical 220 Ohm and 0.25 µF specifications.
