RP115-20-4.7-QD

Overview

The Astrodyne TDI RP115-20-4.7-QD is a single-phase, single-stage power line filter designed for chassis mounting. It features a rated voltage of 250 VAC and a current rating of 20 A at operating frequencies of 50 Hz and 60 Hz. The unit utilizes quick connect tab terminals for electrical termination and incorporates a capacitance value of 4.7 nF (4700 pF). With a leakage current specification of approximately 730 µA to 800 µA, it complies with EN60939 standards and holds UL and CSA certifications. Physical dimensions are 75 mm in length, 50 mm in width, and 30 mm in height.

Feature Summary

• Compact single-stage design for efficient EMI/EMI suppression
• Chassis mount construction for secure installation
• Quick connect terminal interface for simplified wiring

Applications

• Industrial equipment power conditioning
• General purpose electronic systems requiring EMC compliance
• Single-phase AC power input filtering

Procurement Notes

Verify the specific suffix 'QD' corresponds to the quick connect terminal configuration required for your assembly. Confirm that the 20 A current rating and 250 VAC voltage limits align with your system's operational parameters. Ensure chassis mounting provisions match the physical footprint of 75 x 50 x 30 mm. Check for updated certification marks such as UL and CSA on the latest datasheet versions before finalizing procurement.

Selection Notes

Select this component when a compact, single-phase filter is needed for 20 A applications. The 4.7 nF capacitance provides standard attenuation for general EMI environments. Consider the quick connect termination if panel space or soldering constraints exist. Verify that the 730 µA leakage current is acceptable for your safety ground requirements compared to lower-leakage alternatives.

Part Context

This model belongs to the Astrodyne TDI RP115 series, which focuses on compact power line filters. The series offers various current ratings and terminal options. The RP115-20-4.7-QD specifically addresses high-current single-phase needs within a small form factor, distinguishing itself from larger chassis mounts or different terminal styles like stud or wire leads found in other series variants.

Replacement Considerations

Direct substitutes include other RP115 series models with matching 20 A ratings and quick connect terminals, such as RP115-20-4.7-S if stud terminals are adaptable. Cross-reference with RP115-20-4.7-W for wire lead alternatives if termination methods differ. Ensure any replacement maintains the 4.7 nF capacitance and 250 VAC rating.
