FN7660-75-M6

Overview

The Schaffner FN7660-75-M6 is a single-phase LC (Pi) EMI feedthrough filter designed for bulkhead mounting. It features a third-order low-pass topology with one channel, rated for 75 A current and 130 VAC voltage. The internal circuit includes an inductance of 124 nH and capacitance of 100 nF. Operating within a temperature range of -40°C to +100°C, it utilizes M6 threaded terminals for secure installation.

Feature Summary

• LC Pi topology providing third-order attenuation for effective noise suppression
• Bulkhead mounting design with M6 threaded terminals for robust panel integration
• Single-channel configuration optimized for DC power line filtering applications

Applications

• Computer server power inputs
• Medical equipment power supplies
• Industrial control systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct terminal configuration and voltage rating. Confirm RoHS compliance status and lead times directly with authorized distributors or TE Connectivity / Schaffner sales representatives prior to finalizing procurement orders.

Selection Notes

Select this component when high-current DC filtering is required in space-constrained environments. The bulkhead form factor eliminates the need for additional chassis hardware. Ensure the system voltage does not exceed the 130 VAC rating and that the thermal environment remains within the specified operating temperature limits for reliable long-term performance.

Part Context

This part belongs to the FN7660 series of high-performance EMI filters from Schaffner EMC Inc. These components are engineered for demanding industrial and medical applications where strict electromagnetic compatibility standards must be met. The series offers various current ratings and terminal options to suit different power distribution architectures.

Replacement Considerations

The FN7660-63-M6 serves as a verified substitute within the same series, offering identical physical dimensions and electrical topology but with a reduced current rating of 63 A. Verify that the lower current capacity meets the specific application requirements before substitution.
