Overview
The RCS1B-20 is a single-phase EMI/EMC line filter module manufactured by R-K Electronics, Inc. It is designed for surface mount applications and operates at a nominal voltage of 120VAC with a frequency range of 50 to 60Hz. The component features wire leads for connection and includes internal filtering elements specified as 0.47 microfarads capacitance and 22 ohms resistance. The unit utilizes a transient voltage filtering mechanism to suppress electrical noise in power lines.
Feature Summary
- Provides electromagnetic interference (EMI) and radio frequency interference (RFI) suppression for single-phase AC power circuits.
- Designed for surface mount installation to facilitate integration into compact electronic assemblies.
- Incorporates transient voltage filtering capabilities to protect downstream components from electrical noise.
Applications
- Single-phase AC power line filtering in industrial control systems
- Electromagnetic compatibility enhancement for sensitive electronic equipment
- Transient voltage suppression in automation control components
Procurement Notes
Verify the specific ordering suffix and lead time requirements directly with authorized distributors or the manufacturer before placing orders. Confirm that the surface mount package type and wire lead configuration match your PCB design constraints. Ensure compliance with local safety standards for EMI filters used in 120VAC environments. Request updated datasheets to confirm current manufacturing status and availability.
Selection Notes
Select this component when single-phase EMI suppression is required for 120VAC applications. Consider the surface mount form factor if space constraints preclude through-hole mounting. Evaluate the 0.47 microfarad capacitance value against system noise profiles. Verify that the 22 ohm resistance specification aligns with circuit impedance requirements. Compare against other RCS1B series variants for different voltage or capacitance needs.
Part Context
R-K Electronics, Inc. manufactures electronic automation control components, including voltage relays and transient filters. The RCS1B series represents their line of single-phase EMI/EMC filters. These products are typically utilized in electrical controls and industrial automation sectors where noise reduction is critical for reliable operation of sensitive instrumentation and control devices.
Replacement Considerations
Check for direct substitutes within the RCS1B series, such as the RCS1B-7, which shares similar specifications but may differ in lead length or packaging details. Verify pinout compatibility and mounting dimensions before substituting. Consult official documentation to ensure equivalent electrical performance characteristics are maintained in any replacement scenario.
