FN2020-3-06

Overview

The FN2020-3-06 is a single-phase EMC/EMI power line filter from the FN 2020 series, manufactured by Schaffner EMC Inc. It features a two-stage configuration designed for chassis mounting with quick-connect terminals. The component supports an AC voltage rating of 110V or 250V and handles a current capacity of 3A. It operates within a frequency range of DC to 400Hz and functions reliably across a temperature range of -25°C to 100°C.

Feature Summary

• Two-stage filtering architecture for enhanced noise suppression
• Chassis mount design for secure installation
• Quick-connect terminal style for simplified wiring

Applications

• General purpose electronic equipment
• Industrial control systems
• Medical devices

Procurement Notes

Verify the specific voltage rating (110V vs 250V) required for your application against the datasheet specifications. Confirm that the 3A current rating meets the load requirements. Ensure the chassis mounting dimensions and quick-connect terminal types are compatible with the existing assembly. Check for RoHS compliance status if environmental regulations apply to the final product.

Selection Notes

Select this model when a compact, single-phase EMI filter is needed for low-current applications up to 3A. The FN 2020 series offers a balance of performance and size suitable for space-constrained chassis installations. Consider the operating temperature range and certification requirements such as CSA, CQC, or VDE depending on the target market.

Part Context

This component belongs to the FN 2020 series of AC/DC chassis filters. It is part of Schaffner's portfolio of general-purpose EMI filters designed for easy integration into various electronic enclosures. The series is known for providing effective common-mode and differential-mode noise attenuation in a standardized form factor.

Replacement Considerations

Direct substitutes may include other models from the FN 2020 series with similar current ratings, such as the FN2020-6-06 for higher current needs. Cross-brand replacements should match the electrical parameters, mounting style, and terminal configuration. Verify compatibility with safety certifications before substitution.
