RP135-3-.47-QD

Overview

The Astrodyne TDI RP135-3-.47-QD is a single-phase power line filter designed for high-performance electromagnetic interference suppression. It features a rated current of 3 A and a capacitance value of 0.47 nF. The unit supports operation at standard frequencies of 50 Hz and 60 Hz with a voltage rating of 250 VAC. Physical dimensions are 44 mm in length, 44 mm in width, and 17 mm in height. It utilizes quick connect terminals and is intended for panel mount installation. The component operates within a temperature range of -25 °C to +40 °C.

Feature Summary

• Single-stage filtering architecture for effective noise attenuation
• Compact chassis or panel mounting form factor
• Quick connect terminal interface for simplified wiring

Applications

• Electronic equipment requiring EMI/RFI suppression
• Power supply input stages
• Industrial control systems

Procurement Notes

Verify the specific datasheet version for the RP135-3-.47-QD to confirm exact leakage current values and certification status (UL, CSA, EN) prior to integration. Ensure that the operating environment remains within the specified -25 °C to +40 °C temperature range to maintain performance integrity. Confirm mechanical fitment against the 44 x 44 x 17 mm housing dimensions during the design phase.

Selection Notes

Select this component when a low-capacitance single-phase filter is required for 3 A applications. The 0.47 nF capacitance value suggests suitability for scenarios where minimal leakage current is critical compared to higher capacitance alternatives like the 4.7 nF variants. Verify that the quick connect termination style aligns with the available PCB or wire harness connectors in the target assembly.

Part Context

This part belongs to the RP135 series of power line filters manufactured by Astrodyne TDI. The series offers various current ratings and capacitance options to address different filtering requirements. The RP135 designation indicates a specific performance tier within the manufacturer's portfolio, distinct from the RP120 or RP125 series which may feature different physical sizes or current capacities.

Replacement Considerations

Direct substitutes include other RP135 series variants such as RP135-3-2.2-QD or RP135-3-4.7-QD if higher capacitance is acceptable. For identical specifications, verify availability of the exact suffix -QD. Cross-series replacements like RP120 or RP125 require verification of mounting style and current rating compatibility.
