3ESK7

Overview

The TE Connectivity Corcom Filters 3ESK7 is a single-phase EMC/EMI line filter module designed for commercial applications. It features an IEC 320-C14 input connector and utilizes .250-inch (6.35mm) faston terminals for output connections. The component is rated for 3 amperes at 250VAC and operates within the standard 50/60Hz frequency range. It employs a single-stage filtering configuration to attenuate conducted noise, ensuring compliance with electromagnetic interference standards for connected equipment.

Feature Summary

• Integrates an IEC 320-C14 power entry receptacle for standardized input connectivity
• Provides single-stage EMI/RFI attenuation for conducted noise reduction
• Utilizes quick-connect terminal style for simplified circuit integration

Applications

• Commercial electronic equipment requiring EMI suppression
• Industrial control systems needing conducted noise mitigation
• Medical devices adhering to strict electromagnetic compatibility standards

Procurement Notes

Verify that the required current rating of 3A aligns with the system design specifications. Confirm that the .250-inch faston terminal pitch matches the mating connector on the PCB or harness. Ensure the panel mounting requirements are compatible with the flanged installation type specified for this series.

Selection Notes

Select this model when a single-stage filter solution is sufficient for the application's noise environment. Consider the 3A current capacity and 250VAC voltage rating against the load requirements. Evaluate the physical dimensions and flanged mounting style against available chassis space compared to other Corcom series options.
