3FB3-MS

Overview

The TE Connectivity Corcom Filters 3FB3-MS is a single-phase EMC/EMI power line filter module rated for 3 A current and voltages of 120 VAC or 277 VAC at 50 Hz to 60 Hz. It features an inductance of 13.77 mH and utilizes chassis mount installation with Faston terminals. Designed for general-purpose applications, this component effectively suppresses electromagnetic interference in sensitive electronic circuits.

Feature Summary

• Provides effective suppression of electromagnetic interference (EMI) and radio frequency interference (RFI) for single-phase power lines
• Engineered specifically for use with lighting devices, fluorescent lamps, and related lighting ballasts
• Offers compact modular design suitable for integration into various electronic equipment enclosures

Applications

• Lighting devices and fixtures
• Fluorescent lamp systems
• Related lighting ballasts
• General-purpose electronic equipment requiring EMI suppression

Procurement Notes

Verify the specific voltage rating required for your application, as the 3FB3-MS supports both 120 VAC and 277 VAC. Confirm terminal type compatibility with your circuit board layout. Ensure the chassis mounting method aligns with your enclosure design. Check for RoHS compliance status if required by your manufacturing standards. Validate that the 3 A current rating meets your system's maximum load requirements.

Selection Notes

Select the 3FB3-MS when a single-phase solution is needed for lighting or general electronics. Consider its 13.77 mH inductance for adequate noise filtering. The Faston terminal style simplifies assembly compared to soldered options. Chassis mounting provides secure installation in metal enclosures. Evaluate space constraints as it is a modular unit designed for efficient footprint usage.

Part Context

This component belongs to the Corcom Filters series by TE Connectivity, specializing in power line conditioning. The 3FB3-MS variant focuses on single-phase applications, distinguishing itself from three-phase counterparts. It serves as a critical element in maintaining signal integrity within power supplies for lighting and control systems.

Replacement Considerations

Consult official TE Connectivity documentation for verified substitute part numbers. Cross-reference specifications such as current rating, inductance, and terminal type before substitution. Generic equivalents may not match the precise performance characteristics required for certified installations.
