RCY6A-18V

Overview

The RCY6A-18V is a three-phase (Wye) EMC/EMI line filter module manufactured by R-K Electronics, Inc. It is designed for transient voltage suppression and noise filtering in industrial power systems. The unit supports an operating voltage of 600V AC at frequencies between 50 and 60Hz. Key electrical specifications include a capacitance value of 0.47 microfarads per phase and a configuration supporting three-phase or lower connections. The component utilizes wire leads for installation and operates within a temperature range of -40°C to 85°C.

Feature Summary

• Provides transient voltage filtering and EMI/EMC noise suppression for three-phase power lines
• Designed for surface mount or panel integration with wire lead termination
• Operates reliably in industrial environments across a wide temperature spectrum

Applications

• Industrial motor control circuits requiring noise reduction
• Power distribution systems needing transient voltage protection
• General purpose electronic equipment interfacing with AC mains

Procurement Notes

Verify the specific datasheet version from R-K Electronics, Inc. to confirm mechanical dimensions and terminal configurations. Ensure the application voltage does not exceed 600V AC. Confirm that the Wye configuration matches the system topology. Check for any ordering suffixes that may indicate different mounting styles or lead lengths. Validate compliance requirements against local regulatory standards before procurement.

Selection Notes

Select this model when three-phase transient suppression is required for systems up to 600V AC. The 0.47 microfarad capacitance rating suits general-purpose noise filtering applications. Consider the operating temperature range of -40°C to 85°C for environmental suitability. Compare with other RCY series variants if higher current ratings or different capacitance values are needed. Ensure the wire lead format fits the existing assembly constraints.

Part Context

This component belongs to the RCY Series of RC networks and filters produced by R-K Electronics, Inc., a manufacturer established in 1949 specializing in electrical automation control components. The series includes various models tailored for different voltage and capacitance requirements. The RCY6A-18V specifically addresses three-phase Wye configurations, distinguishing it from single-phase or Delta variant models within the same product family.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that any alternative part matches the 600V AC rating, three-phase Wye configuration, and 0.47 microfarad capacitance. Ensure physical compatibility regarding wire lead length and mounting style.
