FN2520-20-103-C1111

Overview

The FN2520-20-103-C1111 is a single-phase EMC/EMI line filter from the FN2520 series, manufactured by TE Connectivity / Schaffner. It features a two-stage filtering architecture designed for high-performance noise suppression in demanding environments. The unit is rated for a continuous current of 20 A and operates at voltages up to 277 VAC, with DC support up to 400 V. Designed for chassis mounting via terminal blocks, it maintains a low profile height of 35 mm. The filter supports standard power frequencies of 50 Hz and 60 Hz, ensuring compatibility with global industrial power standards while providing robust electromagnetic interference protection.

Feature Summary

• Two-stage filtering architecture for enhanced noise attenuation
• Low-profile chassis mount design for space-constrained installations
• Terminal block termination for secure electrical connections
• Optimized for high-current applications in robotics and data centers

Applications

• Robotics systems requiring strict EMC compliance
• Data center power distribution units
• Industrial automation equipment
• High-performance electronic power supplies

Procurement Notes

Verify that the specific part number FN2520-20-103-C1111 matches the required 20 A rating and 277 VAC voltage specifications for your application. Confirm that the chassis mount style and terminal block termination are compatible with your enclosure design. Ensure that the two-stage filtering performance meets the specific EMI/EMC standards required by your target market or industry regulation.

Selection Notes

Select this component when a two-stage filtering solution is necessary for high-current single-phase applications. The FN2520 series is specifically engineered for robotics and data center environments where superior noise suppression is critical. Consider the 35 mm height constraint if vertical space is limited. Verify that the terminal block interface aligns with your wiring harness requirements rather than PCB mount options.

Part Context

This component belongs to the FN2520 series, which offers low-profile, high-performance EMC filtering solutions. The series is tailored for modern electronics such as robotics and data centers. The FN2520-20-103-C1111 variant specifically provides 20 A capacity within this family, distinguishing it from lower or higher current models like the FN2520-10 or FN2520-30 series variants.

Replacement Considerations

Direct substitutes within the same series include other FN2520 variants with different current ratings, such as FN2520-10-103-C1111 or FN2520-30-103-C1111, provided the current load allows. Cross-series replacements from the FN2660 family may be considered if form factor differences are acceptable. Always verify pinout and mounting hole patterns before substitution.
