3EK3

Overview

The TE Connectivity Corcom Filters 3EK3 is a single-phase EMI/RFI power line filter designed for chassis mounting. It features wire lead termination and supports a rated current of 3 A at voltages up to 250 VAC with a 50/60 Hz operating frequency. The component incorporates an inductance of 1.76 mH and maintains a leakage current of 360 uA. Certified by UL, it belongs to the K series within the Corcom product family.

Feature Summary

• Provides electromagnetic interference and radio frequency interference suppression for AC power lines
• Utilizes wire lead termination for direct circuit integration
• Designed for secure chassis or panel installation

Applications

• Industrial control systems requiring EMI filtering
• Medical equipment power supplies
• Commercial electronic devices

Procurement Notes

Verify the specific datasheet version and manufacturing origin before procurement. Confirm that the wire lead style matches the target assembly requirements. Ensure the chassis mounting hole dimensions align with the design enclosure. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this model for applications requiring a 3 A rating and 250 VAC operation. The low leakage current specification makes it suitable for sensitive environments. Consider the wire lead termination method during PCB or harness design. Verify that the physical dimensions fit the available chassis space.

Part Context

This component belongs to the TE Connectivity Corcom Filters K series, which covers ratings from 1 to 10 Amps. The 3EK3 variant specifically addresses single-phase filtering needs with wire leads. It serves as a standard solution for noise reduction in general-purpose electronic equipment.

Replacement Considerations

Part number alias 6609027-6 refers to the same component. Verify mechanical compatibility when substituting with other Corcom K series filters.
