RCY2A-30

Overview

The RCY2A-30 is a three-phase (Wye) transient voltage filter manufactured by R-K Electronics, Inc. It is designed for surface mount applications and operates at a voltage rating of 240VAC with a frequency range of 50 to 60Hz. The module incorporates a 0.47 microfarad capacitor and a 220 ohm, 7-watt resistor. It features two wire leads, each measuring 30 inches in length, facilitating connection within power line systems.

Feature Summary

• Provides transient voltage filtering for three-phase Wye configurations
• Designed for surface mount installation
• Integrates specific capacitive and resistive components for noise suppression

Applications

• Three-phase power line filtering
• EMC/EMI suppression in industrial equipment
• Transient voltage protection for sensitive electronics

Procurement Notes

Verify the exact datasheet version from R-K Electronics, Inc., as specifications may vary between RCY2A-30 and RCY2A-30V. Confirm lead length and mounting requirements match your design constraints. Ensure compatibility with 240VAC systems before procurement.

Selection Notes

Select this component when a surface-mount solution is required for three-phase Wye systems operating at 240VAC. The integrated 0.47µF capacitance and 220Ω resistance are fixed parameters; ensure these values align with your circuit's impedance and filtering needs without modification.

Part Context

This part belongs to the RCY series of transient filters from R-K Electronics, Inc. The series includes variants such as the RCY6A-30R for higher voltage applications. These modules are engineered for compact integration into power distribution units requiring reliable electromagnetic interference reduction.

Replacement Considerations

The RCY2A-30V is a related variant within the same product family. Verify if the 'V' suffix indicates a functional difference or merely packaging variation. No other direct substitutes are publicly confirmed.
