FN2070-3-07

Overview

The Schaffner FN2070-3-07 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It supports a maximum current of 3 A and operates at voltages up to 250 V AC/DC within a frequency range of 0 Hz to 400 Hz. The component utilizes wire leads for termination and features an inductance of 7.8 mH with a capacitance value of 4.7 nF. Physical dimensions are 64.8 mm in length, 49.8 mm in width, and 40.3 mm in height. It functions reliably between -25°C and +100°C, with a leakage current of 660 µA.

Feature Summary

• Provides effective electromagnetic interference suppression through a two-stage filtering architecture.
• Designed for secure installation via chassis mounting configuration.
• Facilitates direct wiring connections using integrated wire lead terminations.

Applications

• Power conditioning systems requiring EMI protection
• Industrial equipment interfacing with AC/DC power lines
• Aviation or ground support electronics operating at 400Hz

Procurement Notes

Verify the specific suffix against official TE Connectivity / Schaffner documentation to confirm exact termination style and electrical ratings. Ensure the selected variant matches the required voltage and current specifications for the target application. Cross-reference part numbers carefully as minor suffix changes may indicate different packaging or terminal configurations.

Selection Notes

Select this model when a compact, single-phase filter is needed for low-current applications up to 3 A. The two-stage design offers enhanced attenuation compared to single-stage alternatives. Verify that the chassis mounting footprint and wire lead lengths fit the enclosure constraints. Confirm compatibility with the system's operating temperature range and frequency requirements.

Part Context

This component belongs to the FN2070 series of AC/DC chassis filters manufactured by TE Connectivity / Schaffner. The series provides various current ratings and termination options for general-purpose EMI suppression. The FN2070-3-07 specifically addresses lower current needs with wire leads, distinguishing it from higher-current bolted variants within the same family.
