FN7611-63-M6S

Overview

The FN7611-63-M6S is a single-phase AC feedthrough capacitor from the Schaffner FN761X series, designed for electromagnetic interference suppression. It features a Y2 circuit topology with a capacitance of 0.15 µF and a rated voltage of 300 VAC. The component supports a maximum DC current of 63 A and has a maximum DC resistance of 470 µΩ. It operates within a temperature range of -40°C to +100°C. The physical dimensions are 32 mm in diameter and height, with a length of 173 mm, utilizing an M6 threaded terminal for panel mounting.

Feature Summary

• Provides high-current EMI attenuation via axial feedthrough architecture
• Utilizes Y2 safety classification for grounded applications
• Supports robust thermal operation across extended industrial ranges

Applications

• Computer server power inputs
• Medical equipment power supplies
• Data lines for mobile devices

Procurement Notes

Verify the specific suffix 'S' against the manufacturer's official documentation to confirm if it denotes a distinct variant or packaging difference compared to the standard FN7611-63-M6. Ensure the selected part matches the required Y2 safety rating and 63A current capacity for the target application. Cross-reference the M6 thread size and 300VAC rating with system specifications before procurement.

Selection Notes

Select this component when high continuous current handling is required alongside effective common-mode noise suppression. The 0.15 µF capacitance offers a balance between filtering performance and leakage current limitations suitable for medical and IT equipment. Ensure the mounting space accommodates the 173 mm length and that the chassis provides adequate grounding for the feedthrough design.

Part Context

This component belongs to the Schaffner FN761X series of feedthrough filters, which are engineered for direct panel penetration mounting. These filters are characterized by their low impedance path to ground and high current capability, making them suitable for demanding power entry applications where space constraints and high performance are critical requirements.

Replacement Considerations

The FN7611-63-M6 is a direct functional equivalent with identical electrical parameters. Verify if the 'S' suffix indicates a specific packaging or marking variation rather than a change in electrical function before substituting.
