FN7511-32-M4

Overview

The Schaffner FN7511-32-M4 is a single-phase AC feedthrough capacitor designed for electromagnetic interference suppression. It features a 32 A current rating and operates at 300 VAC. The component utilizes an M4 threaded stud for bolt mounting, ensuring secure mechanical integration. Key electrical specifications include a capacitance of 10 nF and a maximum leakage current of 3.1 mA at 250 VAC, 50 Hz. It is rated for Y2 safety classification and functions within a temperature range of -40°C to +100°C.

Feature Summary

• Provides effective high-frequency noise attenuation through integrated feedthrough capacitance.
• Ensures personnel safety compliance via Y2 insulation rating.
• Facilitates robust panel mounting using standard M4 threaded terminals.

Applications

• Computer server power input stages
• Medical equipment signal conditioning
• Industrial control system filtering

Procurement Notes

Verify the specific suffix designation against the manufacturer's latest documentation to confirm terminal configuration and insulation class. Ensure that the M4 thread pitch matches the installation interface requirements. Cross-reference the Y2 rating with safety standards applicable to the final assembly environment before procurement.

Selection Notes

Select this component when a compact, high-current feedthrough solution is required for single-phase lines. The 10 nF capacitance offers a balance between noise suppression and leakage current limits. Consider the thermal operating range and mechanical mounting constraints during the design phase to ensure compatibility with the enclosure structure.

Part Context

This part belongs to the FN751x series of feedthrough capacitors from Schaffner. These components are engineered for direct panel mounting, eliminating the need for additional connectors. The series is widely used in applications requiring reliable EMI suppression with minimal footprint and high current handling capabilities.

Replacement Considerations

Check for exact pinout and capacitance value matching. Verify that any substitute maintains the same M4 thread specification and Y2 safety rating to ensure regulatory compliance and mechanical fit without redesigning the mounting hardware.
