RP187-3-1-QD

Overview

The RP187-3-1-QD is a single-phase EMC/EMI power line filter module from the Astrodyne TDI RP187 series. It features a dual-stage design for high-performance noise attenuation. The unit is rated for 250VAC input voltage and supports a continuous current of 3A at 50/60Hz frequencies. It utilizes an IEC 320-C14 inlet interface with quick-connect tab terminations. The chassis-mountable housing measures approximately 77.5mm in length, 50mm in width, and 22.4mm in height. Leakage current specifications are typically listed as 90uA or 180uA depending on configuration.

Feature Summary

• Dual-stage filtering architecture for enhanced EMI/EMI suppression
• IEC 320-C14 inlet compatibility for standard power cord attachment
• Quick-connect tab termination style for rapid circuit integration
• Chassis mount design suitable for panel installation

Applications

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

Procurement Notes

Verify exact leakage current requirements (90uA vs 180uA) against specific safety standards before ordering. Confirm that the quick-connect tab dimensions match the mating connector on the target PCB or terminal block. Ensure the chassis mounting holes align with the enclosure design. Check RoHS compliance status if restricted substances are prohibited in the final assembly.

Selection Notes

Select this model when a compact, dual-stage solution is required for 3A applications. The IEC inlet simplifies cable management compared to wire leads. Consider the physical dimensions (77.5 x 50 x 22.4 mm) during mechanical layout planning. Ensure the operating environment temperature range falls within the component's specified limits for reliable long-term performance.

Part Context

This component belongs to the RP187 series of power line filters manufactured by Astrodyne TDI. The series offers various current ratings and termination options. The RP187-3-1-QD specifically denotes the 3A variant with quick-connect tabs. Other variants in the series may differ in current capacity, voltage rating, or mounting style.

Replacement Considerations

Direct substitutes include other RP187 series models with matching current and voltage ratings but different termination styles. Cross-reference with equivalent dual-stage filters from other manufacturers ensuring identical IEC inlet and chassis mount dimensions. Verify electrical parameters such as capacitance values and attenuation curves match the original design requirements.
