FN2070B-25-08

Overview

The Schaffner FN2070B-25-08 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It supports rated voltages of 110VAC and 250VAC with a current rating of 25A. The component operates within a frequency range of DC to 400Hz and features screw terminals for connection. Certified by UL, CSA, and IEC/EN standards, it is suitable for medical applications due to its B-type construction.

Feature Summary

• Two-stage filtering architecture providing high differential and common-mode attenuation
• B-type configuration optimized for medical equipment safety requirements
• Chassis mount design facilitating easy installation in control panels

Applications

• Medical imaging systems
• Industrial automation controllers
• Power supply units

Procurement Notes

Verify the specific suffix 'B' confirms the medical-grade B-type classification without Y-capacitors if low leakage is required. Confirm terminal type matches the screw specification rather than quick-connect variants. Ensure the voltage rating aligns with the target system's AC or DC input parameters before ordering.

Selection Notes

Select this model when high current handling up to 25A is necessary alongside strict medical compliance. The two-stage design offers superior noise suppression compared to single-stage alternatives. Consider thermal derating factors if operating near the maximum temperature limit of 100°C.

Part Context

This component belongs to the FN2070 series, which provides multi-stage performance for AC/DC applications. The series includes various current ratings from 1A to 36A. The B-suffix denotes a version tailored for medical environments, distinguishing it from standard general-purpose filters in the same family.

Replacement Considerations

FN2070-25-08 serves as a potential substitute but lacks the specific B-type medical certification. Verify that the replacement meets all regulatory requirements for the intended application.
