FN5040-4.5-82

Overview

The Schaffner FN5040-4.5-82 is a single-phase power line filter module designed for chassis mounting. It operates at a rated current of 4.5 A and supports AC voltages up to 250 VAC. The component features a two-stage filtering configuration with an inductance of 13 mH and a capacitance of 2.2 µF, optimized for sine wave applications. It functions within a frequency range of DC to 400 Hz and withstands operating temperatures from -25°C to +100°C.

Feature Summary

• Provides high attenuation performance through a dual-stage filtering architecture.
• Engineered specifically for sine wave signal integrity and noise suppression.
• Designed for secure chassis mounting to ensure stable mechanical installation.

Applications

• Industrial control systems requiring EMI/RFI suppression
• Medical equipment power input stages
• General-purpose electronic devices needing chassis-mounted filtering

Procurement Notes

Verify the specific suffix code against official datasheets to confirm exact electrical ratings and terminal configurations. Ensure compatibility with existing chassis cutouts and mounting hardware. Confirm RoHS compliance status if required by local regulations. Cross-reference safety certifications such as UL or CSA with the target application's regulatory requirements before finalizing procurement.

Selection Notes

Select this model when a compact, chassis-mount solution is required for single-phase AC lines. The 4.5 A rating suits low-to-medium power applications. Consider the 13 mH inductance value for necessary common-mode noise reduction. Verify that the physical dimensions fit the available enclosure space and that the operating temperature range meets environmental conditions.

Part Context

This component belongs to the FN5040 series of power line filters manufactured by Schaffner EMC Inc. The series is characterized by cost-effective solutions for general-purpose filtering needs. These modules integrate safety acceptances and high attenuation performance into a robust chassis-mount package suitable for various industrial and commercial environments.

Replacement Considerations

Consult official Schaffner documentation for direct cross-references. Ensure any substitute matches the 4.5 A current rating, 13 mH inductance, and chassis mount form factor. Verify identical safety certifications and voltage ratings to maintain system compliance and performance integrity.
