FN354-12-05

Overview

The Schaffner FN354-12-05 is a single-phase EMC/EMI power line filter designed for chassis mounting. It supports a rated current of 12 A and operates at AC voltages of 115 VAC or 230 VAC. The component provides two-stage filtering to suppress electromagnetic interference across the DC to 60 Hz frequency range. It utilizes fast-on terminal connections for circuit integration and functions within an operating temperature range of -25°C to +100°C.

Feature Summary

• Two-stage attenuation architecture for enhanced noise suppression
• Fast-on terminal style for simplified wiring integration
• Chassis mount configuration for secure panel installation

Applications

• Industrial control systems
• Power supply units
• General electronic equipment requiring EMI reduction

Procurement Notes

Verify the specific datasheet version and certification status (CSA, ENEC, UR) prior to procurement. Confirm that the fast-on terminal dimensions match the mating connector specifications in your design. Ensure the chassis mounting hole pattern aligns with your enclosure requirements. Check for any recent product change notices regarding packaging or material composition updates.

Selection Notes

Select this model when a single-phase, two-stage solution is required for 12 A applications. Ensure the operating environment stays within the specified -25°C to +100°C temperature range. Verify that the fast-on terminals are compatible with your harness connectors. Consider the physical dimensions for chassis cutout planning during the initial design phase.

Part Context

This component belongs to the FN354 series of single-phase power line filters from Schaffner. The series is engineered for general-purpose EMI suppression in industrial and commercial environments. It complements other single-phase models in the lineup by offering standardized attenuation characteristics for common mode and differential mode noise.

Replacement Considerations

Consult official Schaffner documentation for direct replacements. Cross-referencing requires matching voltage, current, and attenuation curves. Generic substitutes may not meet the same certification standards.
