3EK1

Overview

The TE Connectivity Corcom Filters 3EK1 is a single-phase EMC/RFI power line filter designed for chassis mounting. It features a quick-connect termination style with 0.187-inch (4.7mm) faston terminals. The component is rated for 3A current and 250VAC voltage, operating at 50Hz or 60Hz frequencies. It includes a built-in fuse holder but does not contain a fuse. The unit complies with UL, CSA, and VDE safety standards.

Feature Summary

• Single-stage EMI/RFI filtering capability
• Integrated fuse holder for circuit protection
• Chassis mount installation design

Applications

• General purpose electronic equipment
• High impedance load applications
• Industrial control systems

Procurement Notes

Verify the specific datasheet version and compliance certificates before procurement. Confirm that the required fuse type is sourced separately as the component does not include an internal fuse. Ensure chassis mounting dimensions align with the enclosure design to guarantee proper fit and electrical isolation.

Selection Notes

Select this model when single-stage attenuation is sufficient for the application's noise profile. The 3A rating suits low-power devices, while the 250VAC rating supports standard global mains voltages. Consider the chassis mount form factor if panel penetration is preferred over PCB integration.

Part Context

This component belongs to the TE Connectivity Corcom Filters series, specializing in power line filtration solutions. The 3EK1 variant represents a compact, general-purpose filter module intended for direct connection to AC power inputs in various electronic assemblies requiring basic electromagnetic interference suppression.

Replacement Considerations

Consult official TE Connectivity documentation for verified substitute part numbers. Cross-reference technical specifications such as current rating, voltage limits, and physical dimensions to ensure functional equivalence during replacement scenarios.
