FN7660-100-M8

Overview

The FN7660-100-M8 is a single-channel LC(Pi) EMI feedthrough filter designed for DC applications. It features an axial threaded terminal package with M8 mounting threads and bolt installation. The component has a rated voltage of 130V and handles a current of 100 A. Internal parameters include an inductance of 124nH and capacitance of 0.47µF, resulting in a channel resistance of 0.00025 ohms. Operating temperature ranges from -40°C to 100°C. Dimensions are 32.00mm diameter by 120.00mm length.

Feature Summary

• LC(Pi) topology providing third-order low-pass filtering characteristics
• Axial feedthrough design with M8 threaded terminals for secure bolt mounting
• Capable of handling high continuous current loads up to 100 A
• RoHS3 compliant construction suitable for regulated electronic environments

Applications

• Mobile device data lines
• Computer server power distribution
• Medical equipment signal conditioning

Procurement Notes

Verify the specific suffix M8 confirms the thread size and terminal configuration required for your chassis interface. Confirm that the 130V rating and 100A current capacity align with your system's electrical requirements. Check for RoHS3 compliance if environmental regulations apply. Ensure mechanical clearance matches the 32mm diameter and 120mm length specifications before ordering.

Selection Notes

Select this model when high-current DC filtering is required in space-constrained axial installations. The LC(Pi) structure offers superior attenuation compared to simple capacitors. Compare against the FN7560 series if lower current or different circuit topologies like Y4 are needed. Ensure the operating temperature range covers your environment's extremes.

Part Context

This component belongs to the Schaffner FN766X series of DC feedthrough filters. These components are engineered for robust electromagnetic interference suppression in industrial and medical sectors. The series utilizes ceramic capacitor technology integrated into a conductive housing, providing both filtering and structural mounting capabilities in a single unit.

Replacement Considerations

The FN7660-200-M10 serves as a higher current variant within the same series but requires M10 threading. Verify mechanical compatibility before substitution. No direct pin-for-pin equivalent exists for identical ratings; consult the manufacturer datasheet for alternative LC(Pi) configurations.
