FN2070-25-08

Overview

The Schaffner FN2070-25-08 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It supports rated currents up to 25 A at voltages of 110 VAC or 250 VAC/DC, operating within a frequency range of DC to 400 Hz. The unit features screw terminal connections and includes internal safety components: a 33 µF capacitor, 1.23 mH inductor, and 220 kΩ resistor. Key electrical parameters include a maximum leakage current of 660 µA and a power loss of 9.6 W. It operates reliably between -25°C and +100°C.

Feature Summary

• Two-stage filtering architecture providing high differential and common-mode attenuation
• Chassis mount design with screw terminals for secure installation
• Integrated safety resistors and capacitors for enhanced circuit protection
• Optimized for high-frequency noise suppression in AC/DC environments

Applications

• Industrial machinery power conditioning
• Medical equipment power supplies
• Avionics and aerospace systems
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix '08' corresponds to the required screw terminal configuration and physical dimensions. Confirm that the 25 A rating aligns with your system's continuous load requirements. Ensure compatibility with the 110V/250VAC input voltage range. Check for any regional certification requirements such as UL, CSA, or IEC/EN compliance before finalizing procurement.

Selection Notes

Select this model when high attenuation performance is required for single-phase applications up to 25 A. Consider the FN2070 series if chassis mounting space allows. Compare against lower current variants like FN2070-16-08 if load demands are reduced. Evaluate thermal management needs due to the specified power loss characteristics under full load conditions.

Part Context

Part of the FN2070 series from TE Connectivity Schaffner, designed for mid-stage performance in EMI suppression. The series offers various current ratings and termination options. This specific model represents a higher-current variant suitable for robust industrial and medical power applications requiring reliable noise filtration.

Replacement Considerations

FN2070B-6-06 is listed as an alternative in some databases, though it differs significantly in current rating (6 A vs 25 A) and termination type. Verify functional equivalence carefully. No direct pin-for-pin substitute with identical 25 A rating is explicitly confirmed in the provided source data.
