RP120-20-22-S

Overview

The Astrodyne TDI RP120-20-22-S is a medium-high performance single-stage power line filter designed for AC power applications. It supports a rated voltage of 250 VAC and handles a continuous current of 20 A at operating frequencies of 50 Hz or 60 Hz. The unit incorporates a capacitance value of 22 nF to provide effective electromagnetic interference suppression. It utilizes a stud termination style for secure electrical connections and features chassis mounting for stable installation within equipment enclosures.

Feature Summary

• Single-stage filtering architecture for efficient noise attenuation
• Chassis mount design with stud termination for robust integration
• Rated for 250 VAC and 20 A continuous operation

Applications

• Industrial machinery power conditioning
• Medical equipment EMI suppression
• Commercial IT infrastructure power protection

Procurement Notes

Verify the specific suffix against official datasheets, as variations exist (e.g., -W vs -S). Confirm that the stud termination matches your chassis hole pattern and torque requirements. Ensure the 20 A rating aligns with your system's peak load demands. Cross-reference the 22 nF capacitance value with your EMC compliance testing needs. Always validate RoHS status through the manufacturer's latest documentation before finalizing procurement.

Selection Notes

Select this component when a single-stage solution meets your attenuation requirements without the complexity of dual-stage designs. The 20 A rating suits moderate-power applications where space constraints favor compact chassis mounts. Verify that the 250 VAC rating is sufficient for your local mains supply. Consider the stud termination if quick-connect terminals are unsuitable for your vibration environment.

Part Context

This model belongs to the RP120 series, which offers medium-high performance filtering. It shares the series' focus on balancing size and attenuation. Unlike higher-current variants in the RP135 series, it targets lower amperage loads. The single-stage topology distinguishes it from the dual-stage RP220 series, offering a simpler circuit path for standard noise profiles.
