Overview
The FN2640-20-08-C11 is a single-phase, low-profile IEC inlet EMC/EMI filter manufactured by Schaffner. It features a 20 A current rating and operates at voltages up to 250 VAC within a frequency range of 0 Hz to 60 Hz. The unit utilizes an IEC C20 inlet for input termination and provides threaded stud output connections. Key electrical specifications include a maximum leakage current of 370 µA and an internal capacitance of 4.7 nF. Designed as a one-stage filter, it supports rack mounting configurations.
Feature Summary
- Low-profile design optimized for space-constrained installations
- High-performance EMI/EMC filtering capabilities
- IEC inlet configuration with threaded stud outputs
Applications
- Industrial machinery power supplies
- Medical equipment power inputs
- Telecommunications infrastructure
Procurement Notes
Verify the specific suffix codes against official datasheets to confirm terminal types and mounting hardware compatibility. Ensure that the rated voltage and current parameters align with the target application's electrical requirements before procurement. Cross-reference manufacturer documentation for any updates regarding compliance certifications or material composition changes.
Selection Notes
Select this component when a single-phase solution with high current capacity is required in a compact form factor. The threaded stud output is suitable for robust industrial connections. Consider the leakage current limits if used in sensitive medical or safety-critical environments where strict isolation standards apply.
Part Context
This model belongs to the FN2640 series, which offers a range of dedicated single-phase filters. The series is characterized by its low-profile construction and high performance in EMC/EMI suppression. It serves as a specialized variant within Schaffner's broader portfolio of power line filters designed for demanding electronic applications.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify that any replacement maintains identical current ratings, voltage limits, and physical dimensions to ensure proper fit and function in existing assemblies.
