FN2090BZ-20-06

Overview

The Schaffner FN2090BZ-20-06 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It features a rated current of 20 A and a voltage rating of 250 VAC. The unit utilizes fast-on terminals for electrical connection and operates within a frequency range of 0 Hz to 400 Hz. Physical dimensions are approximately 94 mm in length, 56 mm in width, and 45.4 mm in height. It complies with UL, CSA, and IEC/EN standards.

Feature Summary

• Two-stage filtering architecture for enhanced noise attenuation
• Chassis mount design for secure mechanical installation
• Fast-on terminal configuration for rapid wiring

Applications

• Industrial machinery power conditioning
• Medical equipment electromagnetic compatibility
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'BZ' against official datasheets to confirm flange mounting variations or insulation class differences compared to standard chassis mounts. Confirm lead times directly with TE Connectivity/Schaffner distributors as supply chain status fluctuates. Ensure panel cutout dimensions match the physical specifications provided in the manufacturer documentation before ordering.

Selection Notes

Select this component when high current handling up to 20 A is required alongside robust EMI suppression in a compact chassis-mount form factor. Verify that the operating environment temperature remains within the specified -25°C to +100°C range. Ensure the application voltage does not exceed the 250 VAC rating and that fast-on terminal accessibility is available in the design layout.

Part Context

This part belongs to the FN2090 series of AC power line filters manufactured by Schaffner, now part of TE Connectivity. The series is engineered for general-purpose EMI suppression in single-phase applications. The FN2090BZ variant specifically denotes chassis mounting with fast-on terminals, distinguishing it from PCB or cable-mounted alternatives within the broader product family.

Replacement Considerations

Consult official cross-reference guides for direct substitutes. Generic replacements may lack identical leakage current characteristics or certification approvals. Verify that any alternative maintains the same 20 A rating and two-stage topology to ensure equivalent performance.
