FN2020-3-07

Overview

The Schaffner EMC Inc. FN2020-3-07 is a single-phase EMC/EMI power line filter designed for chassis mounting. It supports a rated AC voltage of 250V and a current rating of 3A. The component operates within a frequency range of DC to 400Hz and features wire lead termination. It is certified by CSA, ENEC, and UR agencies.

Feature Summary

• Single-stage filtering configuration for electromagnetic interference suppression
• Chassis mount installation with wire lead connections
• Certified for international safety standards including CSA, ENEC, and UR

Applications

• General purpose EMI/EMC filtering in electronic equipment
• Power supply input stages operating up to 400Hz
• Industrial control systems requiring chassis-mounted filtration

Procurement Notes

Verify the specific datasheet version for leakage current specifications, which typically range between 0.66 mA and 1.33 mA at rated voltage. Confirm that the wire lead termination style matches your assembly requirements. Ensure the chassis mounting dimensions align with your enclosure design before finalizing procurement.

Selection Notes

Select this model for applications requiring a single-stage filter solution with wire leads rather than panel terminals. It is suitable for environments where CSA, ENEC, or UR certifications are mandatory. Consider the 3A current limit and 250VAC rating when designing circuits to ensure adequate headroom for operational loads.
