3VSK3

Overview

The TE Connectivity Corcom Filters 3VSK3 is a high-performance single-phase EMI/RFI line filter designed for switch-mode power supply (SMPS) emission control. It operates at AC 120V or 250V with a 3A current rating. The unit features a two-stage configuration and chassis mount installation. Termination is achieved via quick connect terminals sized 0.187 inches (4.7mm). Certified by CSA, UR, and VDE, it supports 50/60Hz frequencies.

Feature Summary

• High-performance RFI filtering specifically engineered for SMPS emission control
• Two-stage circuit configuration for enhanced noise suppression
• Chassis mount design with quick connect termination style

Applications

• Switch-mode power supply (SMPS) systems
• Electronic equipment requiring EMI/RFI noise reduction
• Industrial control panels

Procurement Notes

Verify the specific voltage rating (120VAC vs 250VAC) and current capacity against your system requirements before procurement. Confirm that the chassis mounting dimensions and quick connect terminal spacing match your enclosure layout. Ensure compliance with local safety certifications such as UL or CSA is required for your target market.

Selection Notes

Select this component when high attenuation is needed for switch-mode power supplies. Compare the two-stage performance against single-stage alternatives if space permits. Verify the operating temperature range and leakage current specifications to ensure compatibility with sensitive downstream electronics and safety standards.

Part Context

This part belongs to the K Series of Corcom filters, which are characterized by high performance in radio frequency interference suppression. It serves as a critical component for meeting electromagnetic compatibility (EMC) regulations in electronic devices powered by switch-mode supplies.

Replacement Considerations

Consult official TE Connectivity substitution guides for verified equivalents. Generic cross-references may not match the specific two-stage topology or insertion loss characteristics required for SMPS applications.
