FN2070M-25-08

Overview

The Schaffner FN2070M-25-08 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It supports rated currents from 25 to 28.8 A with a voltage rating of 110/250 VAC and 250 VDC. The component operates within a frequency range up to 400 Hz and features screw terminals for connection. Key electrical parameters include a leakage current ranging from 2.13 to 3.69 mA. It provides high differential and common-mode attenuation suitable for demanding electromagnetic compatibility applications.

Feature Summary

• Two-stage filtering architecture providing high differential and common-mode attenuation
• Designed for easy and fast chassis mounting installation
• Available in medical versions (B type) without Y-capacitors
• Utilizes chokes with high saturation resistance and excellent thermal behavior

Applications

• Medical equipment requiring low leakage current options
• Industrial machinery requiring robust EMI suppression
• Power supply units needing high attenuation performance
• Aviation or ground support equipment operating at 400 Hz

Procurement Notes

Verify the specific suffix designation against official Schaffner documentation to confirm exact electrical characteristics, as variations exist within the FN2070 series. Ensure the selected variant meets the required safety certifications such as UL, CSA, or IEC/EN standards for the target application region. Confirm terminal type and mounting dimensions match the mechanical design constraints before finalizing procurement.

Selection Notes

Select this component when high conducted attenuation is required for single-phase AC/DC systems. Consider the FN2070M variant specifically if medical compliance or low leakage current is a priority. Evaluate the thermal behavior under maximum load conditions to ensure the choke saturation resistance remains effective. Compare physical dimensions against available chassis space to verify fitment for the chassis mount style.
