FN2090-30-08

Overview

The Schaffner FN2090-30-08 is a single-phase, multi-stage EMI power line filter rated for 30A at 250VAC. Designed for the 0Hz to 400Hz frequency range, it utilizes a threaded stud flange mount configuration. The unit provides general-purpose noise attenuation suitable for medical and industrial applications requiring robust electromagnetic interference suppression.

Feature Summary

• Multi-stage EMI attenuation architecture
• Threaded stud flange mounting interface
• High current capacity design

Applications

• Medical equipment power supplies
• Industrial machinery control systems
• General purpose AC power line filtering

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm terminal type and leakage current specifications. Ensure the mounting hole pattern matches the chassis design. Confirm voltage ratings align with the local electrical infrastructure standards before integration into the final assembly.

Selection Notes

Select this component when high current handling up to 30A is required in a single-phase configuration. The flange mount style simplifies installation on metal enclosures. Consider the physical dimensions and stud size during mechanical layout planning to ensure adequate clearance for wiring and heat dissipation.

Part Context

This part belongs to the FN2090 series of single-phase EMI filters from Schaffner. The series is characterized by its compact form factor and high performance in noisy environments. It is commonly used where space constraints exist but significant current carrying capability is necessary for reliable operation.

Replacement Considerations

Check for equivalent parts within the FN2090 family with different current ratings or terminal configurations. Verify that any substitute maintains the same flange mounting geometry and electrical ratings to ensure compatibility with existing hardware.
