3EHQ8

Overview

The TE Connectivity Corcom 3EHQ8 is a single-phase EMC/EMI line filter rated for 3 A at 250 VAC and 50/60 Hz. It features a two-stage design with IEC 320-C14 input termination and wire lead outputs. The unit supports chassis mounting via a flange and exhibits a leakage current of 5 uA. Certified by UL, CSA, and VDE, it operates within a temperature range of -10°C to 40°C.

Feature Summary

• Two-stage filtering architecture for enhanced noise suppression
• Low leakage current design suitable for sensitive applications
• IEC 320-C14 input interface with wire lead output configuration

Applications

• Medical power supplies requiring low leakage current
• Industrial equipment needing EMI/RFI suppression
• Chassis-mounted electronic systems

Procurement Notes

Verify the specific suffix (e.g., M) against official datasheets to confirm terminal type and mounting variations. Ensure compliance requirements such as UL, CSA, or VDE match the target application's regulatory standards. Confirm input/output configurations align with system integration needs before procurement.

Selection Notes

Select this component for applications requiring certified single-phase filtration with minimal leakage. The 3 A rating and 250 VAC specification define its electrical limits. Consider the bulkhead/chassis mounting style and wire lead outputs when designing enclosure layouts and wiring harnesses.

Part Context

This component belongs to the TE Connectivity Corcom HQ series, designed for single-phase power line filtering. It serves as an electromagnetic interference suppression device for AC power inputs in regulated environments.

Replacement Considerations

Check for equivalent ratings in the same series. Verify that substitute parts maintain identical voltage, current, and certification profiles.
