RP120-40-4.7-S

Overview

The Astrodyne TDI RP120-40-4.7-S is a single-phase, single-stage power line filter designed for electromagnetic interference suppression. It features a 40 A current rating and a 250 VAC voltage rating, operating at 50 Hz or 60 Hz frequencies. The unit utilizes a threaded post (M4) termination style for secure chassis mounting. Key electrical specifications include a capacitance of 4.7 nF and a leakage current of 800 uA. The component complies with UL, CSA, and EN standards, ensuring safety and regulatory adherence for industrial applications.

Feature Summary

• Single-stage filtering architecture for effective EMI/EMI noise reduction
• Chassis mount design with M4 threaded post terminations
• Compliance with major international safety certifications

Applications

• Industrial machinery power input stages
• Medical equipment power supplies
• Commercial IT infrastructure systems

Procurement Notes

Verify the specific ordering suffix to confirm the exact termination type and certification package. Ensure the application environment temperature remains within the specified operational limits. Confirm that the mounting surface provides adequate grounding continuity for the chassis mount configuration. Cross-reference the datasheet for mechanical dimensions to ensure fit within the intended enclosure space.

Selection Notes

Select this model when a single-phase solution with a 40 A capacity is required. The 4.7 nF capacitance value indicates suitability for standard frequency noise attenuation. Consider the M4 termination requirement for installation planning. Evaluate if the single-stage topology meets the specific attenuation requirements of the target application compared to dual-stage alternatives.

Part Context

This component belongs to the RP120 series from Astrodyne TDI, which focuses on medium-high performance power line filtration. The series offers various current ratings and termination options to accommodate diverse chassis mounting needs. It serves as a critical interface component between the AC power source and sensitive electronic loads.

Replacement Considerations

Direct substitutes may include other models within the RP120 series with matching 40 A ratings. Verify compatibility by comparing voltage ratings, capacitance values, and physical mounting dimensions. Ensure any replacement maintains the same safety certifications required for the original system design.
