RP2180-3-.47-QD

Overview

The Astrodyne TDI RP2180-3-.47-QD is an ultra-compact, single-stage AC power line filter designed for 1-phase applications. It features a rated voltage of 250 VAC and a current rating of 3 A. The unit incorporates a capacitance value of 0.47 nF (470 pF) and exhibits a leakage current of 80 uA. Designed for chassis mounting with tab connectors, it operates at standard frequencies of 50 Hz and 60 Hz. The component measures 48 mm in length and 58.5 mm in height.

Feature Summary

• Ultra-compact physical design optimized for space-constrained installations
• Single-stage filtering architecture providing essential EMI suppression
• Low leakage current specification suitable for sensitive equipment safety requirements

Applications

• Medical electronic devices requiring low leakage current
• Compact industrial control systems
• Information technology hardware with limited internal volume

Procurement Notes

Verify the specific suffix QD against official manufacturer documentation to confirm terminal type and compliance certifications. Ensure the operating environment temperature remains within the specified limits defined in the datasheet. Confirm that the 3 A current rating aligns with the system's maximum load requirements to prevent thermal issues during continuous operation.

Selection Notes

Select this component when space constraints are critical and single-stage attenuation is sufficient for the application's noise profile. Compare the 0.47 nF capacitance value against regulatory leakage current limits for the target market. Evaluate the tab connector style against available PCB or wire termination options to ensure mechanical compatibility without requiring additional adapters.

Part Context

This model belongs to the RP2180 series, which focuses on ultra-compact form factors for single-phase AC filtering. Unlike higher-current variants in the RP100 or RP120 series, this part prioritizes minimal footprint over high amperage capacity. It serves as a specialized solution for low-power applications where standard filters would exceed available enclosure dimensions.

Replacement Considerations

Direct substitutes include other Astrodyne TDI models within the RP2180 series with matching current and capacitance ratings. Verify that any alternative maintains the same tab connector configuration and chassis mount dimensions to avoid redesigning the mounting structure or wiring harness.
