RP225-4-1-QD

Overview

The RP225-4-1-QD is a single-phase, two-stage power line filter from the Astrodyne TDI RP225 series. It features a 4A current rating and a 250 VAC voltage rating for operation at 50 Hz or 60 Hz frequencies. The unit utilizes quick connect terminals for electrical termination and supports chassis mounting. Key specifications include a capacitance of 1 nF and a leakage current range of 0 A to 1.8 mA. The component complies with UL, CSA, and EN standards.

Feature Summary

• Dual-stage filtering architecture designed for high-performance electromagnetic interference suppression
• Quick connect terminal configuration facilitates rapid electrical integration
• Chassis mount design ensures secure mechanical installation in equipment enclosures

Applications

• Medical equipment power conditioning
• Industrial control systems
• Test and measurement instrumentation

Procurement Notes

Verify that the specific part number matches the required current and voltage ratings for your application. Confirm compliance requirements such as UL, CSA, or EN certifications are necessary for your region. Ensure the chassis mounting style and quick connect terminals align with your system's mechanical and electrical interface constraints before finalizing procurement.

Selection Notes

Select this model when a compact, single-phase solution is needed for low-current applications requiring dual-stage attenuation. The 4A rating suits sensitive electronics where leakage current must be minimized. Verify that the 250 VAC rating is sufficient for the local mains supply. Consider the physical dimensions and chassis mounting requirements during the mechanical design phase to ensure proper fit within the enclosure.

Part Context

This component belongs to the RP225 series of power line filters manufactured by Astrodyne TDI. The series offers various current ratings and capacitance values to suit different EMI suppression needs. The RP225 models are characterized by their dual-stage construction and robust chassis-mount designs, providing reliable performance in demanding environments compared to standard single-stage alternatives.

Replacement Considerations

Direct substitutes within the same series include RP225-6-3.3-QD and RP225-12-3.3-QD, which offer higher current capacities but may differ in physical size and capacitance. Ensure any replacement maintains the required 4A minimum rating and compatible terminal type.
