3ET1

Overview

The TE Connectivity Corcom Filters 3ET1 is a single-phase EMC/EMI line filter rated for 3 A at 250 VAC, 50/60 Hz. It features a single-stage configuration with quick connect terminals measuring 0.250 inches on both input and output sides. The unit utilizes a flanged mounting style suitable for panel installation. This component is designed to suppress electromagnetic interference in power lines within commercial applications.

Feature Summary

• Single-stage EMI/RFI filtering capability
• Flanged chassis or panel mount design
• Quick connect terminal interface

Applications

• Commercial electronic equipment power entry
• General purpose EMC suppression
• Industrial control systems

Procurement Notes

Verify the exact datasheet version for the 3ET1 part number as public records primarily detail the 3EHQ1 variant within this series. Confirm terminal pitch and mounting hole dimensions against your enclosure specifications. Ensure the single-stage attenuation meets your specific EMI requirements before finalizing procurement.

Selection Notes

Select this model when a compact, single-stage solution is sufficient for low-current applications up to 3 A. The flanged design simplifies mechanical integration compared to chassis-mount variants. Verify that the quick-connect terminals match the wire gauge and connector type used in the downstream circuitry.

Part Context

This component belongs to the TE Connectivity Corcom Filters HQ series, which specializes in single-phase power line filters. The series offers various current ratings and configurations, with the 3ET1 representing a specific 3 A flanged option. It complements other Corcom products like the IH and SRB series for broader system filtering needs.

Replacement Considerations

Public documentation lists the FN2080B-3-06 from TE Connectivity Schaffner as a confirmed substitute for related 3 A models in this category. Verify electrical and mechanical compatibility before substitution.
