RP187-1-4.7-QD

Overview

The RP187-1-4.7-QD is a single-phase, dual-stage power line filter from the Astrodyne TDI RP187 series. It features an IEC C14 inlet and is rated for 1 A current at 250 VAC. The unit incorporates 4.7 nF capacitance and utilizes quick-connect (QD) tab terminals for circuit attachment. Designed for chassis mounting, it operates within a temperature range of -25°C to +100°C at 50/60 Hz frequencies.

Feature Summary

• Dual-stage filtering architecture for enhanced EMI/EMI suppression
• Integrated IEC C14 power inlet connector
• Quick-connect terminal configuration for rapid assembly

Applications

• General purpose electronic equipment
• Medical devices requiring certified filtration
• Industrial control systems

Procurement Notes

Verify compliance with specific regional safety standards such as CE, CSA, cURus, or ENEC based on the target market requirements. Confirm that the chassis mounting dimensions and terminal spacing align with the mechanical design constraints of the host enclosure before finalizing procurement.

Selection Notes

Select this model when a compact, dual-stage solution is required for low-current applications up to 1 A. Ensure the operating environment stays within the specified -25°C to +100°C thermal limits. Verify that the quick-connect tab style matches the available mating connectors in the system design.

Part Context

This component belongs to the RP187 series of high-performance IEC inlet filters. The series offers various current ratings including 1A, 3A, 6A, 10A, and 20A options. The suffix QD indicates the use of quick-connect tabs, while other variants may offer wire leads.

Replacement Considerations

Cross-reference with other RP187 series models if different current ratings are needed. Verify that substitute parts maintain the same dual-stage topology and IEC C14 inlet form factor to ensure mechanical compatibility.
