RP135-1-4.7-QD

Overview

The RP135-1-4.7-QD is a single-stage, one-phase power line filter from the Astrodyne TDI RP135 series. It features a maximum current rating of 1 A and a voltage rating of 250 VAC. The unit includes a capacitance value of 4.7 nF (4700 pF) and operates at frequencies of 50 Hz or 60 Hz. Designed for surface mount installation, it utilizes threaded terminal connections. The component complies with UL, CSA, and EN safety standards.

Feature Summary

• Single-stage EMI filtering architecture
• Surface mount chassis mounting style
• Threaded terminal connection interface

Applications

• Medical equipment power supplies
• Industrial control systems
• Test and measurement instruments

Procurement Notes

Verify the specific datasheet version to confirm exact leakage current values and insertion loss curves, as these parameters can vary by manufacturing batch. Ensure the selected variant matches the required mounting hole pattern and terminal thread specifications for your chassis design. Cross-reference the compliance certificates (UL, CSA, EN) with local regulatory requirements before finalizing procurement.

Selection Notes

Select this model when a compact, surface-mount solution is required for low-current applications up to 1 A. The 4.7 nF capacitance provides standard attenuation for common-mode noise. Verify that the threaded terminals are compatible with available wiring harnesses. Consider thermal derating if operating near the maximum temperature limits defined in the official datasheet.

Part Context

This component belongs to the RP135 family of high-performance single-stage filters. The series offers various current ratings and capacitance options to suit different power levels. The RP135-1-4.7-QD specifically targets low-power applications requiring robust EMI suppression in a small footprint.

Replacement Considerations

Direct substitutes include other RP135 series variants with similar current and capacitance ratings, such as RP135-2-4.7-QD or RP135-0.5-4.7-QD, provided the current rating meets or exceeds system requirements. Ensure mechanical compatibility and electrical specifications match before substitution.
