3EXP

Overview

The TE Connectivity Corcom Filters 3EXP is a single-phase EMI/RFI line filter designed for through-hole mounting. It operates at a rated AC voltage of 250V and supports a current rating of 3A at 50/60Hz frequencies. The component features a single-stage configuration with a minimum inductance of 2.3mH. This filter is intended for general-purpose applications to suppress electromagnetic interference in power lines.

Feature Summary

• Single-phase EMI/RFI noise suppression
• Through-hole terminal connection style
• Single-stage filtering configuration

Applications

• General purpose power line filtering

Procurement Notes

Verify the specific datasheet version for the 3EXP part number, as manufacturer documentation may list it under broader series classifications like the HQ or S series depending on regional variants. Confirm that the through-hole mounting requirement aligns with your PCB design constraints before procurement. Ensure compliance with relevant safety certifications such as UL or CSA if required by your target market regulations.

Selection Notes

Select the 3EXP when a compact, single-stage solution is sufficient for low-current (3A) applications requiring through-hole integration. Compare its 2.3mH inductance against system noise profiles to ensure adequate attenuation. Consider alternative chassis-mount models if panel installation is preferred over PCB mounting.

Part Context

This component belongs to the TE Connectivity Corcom Filters portfolio, which specializes in electromagnetic compatibility solutions. The 3EXP represents a basic entry-level filter within their single-phase lineup, focusing on essential noise reduction for commercial and industrial equipment without complex multi-stage architectures.
