FN2070B-3-07

Overview

The Schaffner FN2070B-3-07 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It supports AC voltages of 110V and 250VAC with a rated current of 3A. The component operates within a frequency range of DC to 400Hz and features wire lead termination. Key electrical specifications include a leakage current of 660uA and a maximum power loss of 1.8W. It functions reliably across an operating temperature range of -25°C to +100°C.

Feature Summary

• Two-stage filtering architecture for enhanced noise suppression
• Chassis mount design with wire leads for secure installation
• Certified for international safety standards including UL, CSA, and IEC/EN

Applications

• Medical equipment power supplies
• Industrial control systems
• Information technology hardware

Procurement Notes

Verify the specific suffix code against official datasheets to confirm terminal type and certification status. Ensure the application voltage matches the 110V/250VAC rating. Confirm thermal management requirements align with the 100°C maximum operating temperature limit before procurement.

Selection Notes

Select this model for applications requiring compact, high-performance EMI filtration in single-phase circuits. The two-stage design offers superior attenuation compared to single-stage alternatives. Verify that the 3A current rating meets the load requirements and that chassis mounting is feasible within the enclosure design constraints.

Part Context

This component belongs to the FN2070 series of AC/DC chassis filters manufactured by Schaffner EMC Inc., now part of TE Connectivity. The series is engineered for demanding environments where space is limited but high noise immunity is required. It serves as a critical interface for protecting sensitive electronics from conducted interference.

Replacement Considerations
