RP125-45-4.7-C

Overview

The RP125-45-4.7-C is a single-phase, single-stage power line filter from the Astrodyne TDI RP110 series. It features a chassis mount design with stud termination for secure installation. The unit is rated for 45 A current and 250 VAC voltage at 50/60 Hz operating frequencies. Key electrical specifications include a maximum leakage current of 400 uA and a capacitance value of 4.7 nF. Physical dimensions are 108 mm in length, 76 mm in width, and 64 mm in height, with an approximate weight of 1 kg. It complies with EN60939 standards.

Feature Summary

• Single-stage EMI/EMI filtering architecture designed for high-performance noise suppression
• Robust chassis mount construction utilizing stud termination for reliable grounding
• Low leakage current specification suitable for sensitive medical or safety-critical applications

Applications

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

Procurement Notes

Verify the specific suffix 'C' indicates terminal block configuration versus other variants like 'S' for studs. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure mechanical mounting holes align with chassis specifications. Validate thermal derating requirements if operating near maximum temperature limits.

Selection Notes

Select this model when a single-phase solution is required for currents up to 45 A. The low leakage current makes it appropriate where safety isolation is critical. Compare physical dimensions against available panel space. Consider the stud termination method for vibration-resistant environments compared to PCB mount alternatives.

Part Context

This component belongs to the RP110 series of power line filters manufactured by Astrodyne TDI. The series offers various current ratings and termination styles. The RP125 variant specifically addresses higher current demands within the single-phase segment. It serves as a passive electromagnetic interference mitigation device for AC power inputs.

Replacement Considerations

The RP125-45-4.7-S is a related variant within the same series featuring stud termination instead of terminal blocks. Verify that the termination style matches the existing wiring harness before substitution. Electrical ratings remain consistent between these suffixes.
