FN7661-200-M10

Overview

The FN7661-200-M10 is a feed-through EMI filter from the Schaffner FN766X series, designed for high-current applications. It features an LC Pi topology with a third-order low-pass configuration. The component supports a rated voltage of 130V DC or AC and handles a maximum current of 200A. Key electrical parameters include an inductance of 124nH and a capacitance of 4700nF (4.7µF). It utilizes axial threaded terminals for bolt installation and operates within a temperature range of -40°C to +100°C.

Feature Summary

• Provides effective electromagnetic interference suppression through a third-order LC Pi filter topology.
• Capable of handling high continuous currents up to 200A with low insertion loss characteristics.
• Features robust mechanical construction with axial threaded terminals for secure bolt mounting.

Applications

• Power distribution units in industrial automation systems
• High-current data lines in mobile equipment
• DC power supply input filtering

Procurement Notes

Verify the specific suffix M10 corresponds to the required terminal thread size and mounting configuration. Confirm that the 130V rating and 200A current capacity align with the system's operational requirements. Check for RoHS3 compliance status if environmental regulations apply. Ensure the physical dimensions fit the available enclosure space.

Selection Notes

Select this component when high current handling is critical alongside significant EMI attenuation. The LC Pi structure offers superior noise reduction compared to simple capacitors. Consider the thermal management capabilities given the 200A load. Verify compatibility with the existing busbar or cable termination methods using the specified threaded terminals.
