FN2070A-25-08

Overview

The Schaffner FN2070A-25-08 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It supports rated currents up to 25 A and operates at voltages of 250 VAC or 250 VDC across frequencies from DC to 400 Hz. The unit utilizes screw terminals for connection and features UL, CSA, and IEC/EN compliance. Key electrical parameters include a leakage current of 660 µA and a maximum operating temperature of +100°C.

Feature Summary

• Two-stage filtering architecture providing high differential and common-mode attenuation
• Chassis mount design optimized for easy and fast installation
• High saturation resistance chokes ensuring excellent thermal behavior

Applications

• Industrial equipment requiring conducted noise suppression
• Power supply input stages in electronic systems
• Applications necessitating low leakage current safety compliance

Procurement Notes

Verify the specific suffix 'A' indicates the safety version with low capacitance requirements. Confirm terminal type matches system wiring needs. Check RoHS status and certification marks against target market regulations before finalizing procurement orders.

Selection Notes

Select this model when high attenuation performance is required alongside strict leakage current limits. Ensure the chassis mounting footprint accommodates the physical dimensions. Verify that the 25 A rating aligns with the peak load requirements of the connected circuitry.

Part Context

This component belongs to the FN2070 series, which offers multi-stage performance AC/DC EMI filters. The series ranges from 1 to 36 A ratings. The 'A' designation typically denotes a safety-critical variant with reduced Y-capacitance compared to standard versions.

Replacement Considerations

FN2070-25-08 serves as a potential substitute if leakage current constraints are less stringent. Verify dimensional compatibility and terminal configuration before substitution.
