RCY6A-18

Overview

The RCY6A-18 is a three-phase (Wye) EMC/EMI line filter module manufactured by R-K Electronics, Inc. It is designed for general-purpose applications requiring protection against electromagnetic interference in AC power systems. The unit operates at a rated voltage of 600VAC and supports frequencies of 50 to 60Hz. It features wire leads for connection and is built to withstand operating temperatures ranging from -40°C to 85°C.

Feature Summary

• Provides three-phase EMC/EMI noise suppression for Wye configurations
• Rated for 600VAC operation at standard industrial frequencies
• Constructed with wire leads for direct integration into power circuits

Applications

• General-purpose industrial power line filtering
• Electromagnetic interference suppression in three-phase systems
• Protection of sensitive equipment from line noise

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as RCY6A-30 or RCY6A-72 exist within the same family but differ in capacitance and resistance values. Confirm that the Wye configuration matches your system requirements. Ensure the 600VAC rating aligns with your operational voltage levels. Check for RoHS compliance status if required by your procurement standards. Always cross-reference the datasheet for exact physical dimensions and mounting specifications before finalizing purchase orders.

Selection Notes

Select this component only if your application requires a three-phase Wye configuration filter. Ensure the system voltage does not exceed 600VAC. Consider the operating temperature range of -40°C to 85°C for environmental compatibility. Verify that wire lead termination is suitable for your assembly process compared to surface mount alternatives like the RCY6A-72R.

Part Context

This part belongs to the RCY6A series of power line filter modules from R-K Electronics. The series includes various models differentiated by internal component values, such as the RCY6A-30 which specifies 220 ohms and 0.47 microfarads. The RCY6A-18 serves as a specific variant within this lineup, distinct from transient voltage filters like the RCY6A-18V.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Variants within the RCY6A series, such as RCY6A-30 or RCY6A-72, share similar form factors but may have different electrical characteristics. Do not assume interchangeability without verifying specific circuit requirements against the target component's datasheet.
