3VS1

Overview

The TE Connectivity Corcom Filters 3VS1 is a single-phase EMC/EMI line filter designed for chassis or panel mounting. It features a two-stage configuration with quick-connect terminals rated for 0.187-inch (4.7mm) spade connectors. The component supports AC voltages of 120V and 250V at 50/60Hz frequencies, handling a continuous current of 3A. It includes integrated fuse holders for dual fuses, though fuses are not included. The unit is certified by CSA, UL, and VDE agencies.

Feature Summary

• Two-stage EMI/RFI filtering architecture for enhanced noise attenuation
• Integrated dual fuse holder capability for circuit protection
• Quick-connect terminal interface for simplified wiring
• Flange mount installation style for secure chassis integration

Applications

• Industrial automation equipment
• Medical diagnostic devices
• Commercial electronic systems requiring EMI suppression

Procurement Notes

Verify the specific voltage rating requirement against the application's operational range, as the component supports both 120VAC and 250VAC configurations. Confirm that the mounting surface accommodates the flange-style installation geometry. Ensure that the selected fuse specifications match the internal holder requirements, noting that fuses are supplied separately. Cross-reference certification marks such as UL, CSA, and VDE to ensure compliance with regional regulatory standards for the intended market deployment.

Selection Notes

Select this model when a compact, two-stage solution is required for single-phase power entry applications. The 3A current rating suits low-power commercial and medical electronics. The flange mount design offers stability compared to snap-in variants. Verify that the quick-connect terminal size matches the system's wiring harness. Consider the integrated fuse holder feature if upstream protection is needed within the power entry module itself.
