FN2090B-1-06

Overview

The Schaffner FN2090B-1-06 is a single-phase EMI/RFI power line filter designed for chassis mounting. It supports a maximum current of 1 A and operates at voltages up to 250 V AC or DC within the 0 Hz to 400 Hz frequency range. The component utilizes fast-on terminals for connection and features a two-stage filtering configuration. Key electrical parameters include an inductance of 33 mH, capacitance of 330 nF, and leakage current of 0.5 mA. It functions reliably within an operating temperature range of -25°C to 100°C.

Feature Summary

• Provides effective attenuation of electromagnetic interference through a two-stage LC filter architecture.
• Features fast-on terminal connections for simplified integration into equipment panels.
• Designed for robust performance across wide industrial temperature variations.

Applications

• Medical equipment requiring strict EMC compliance
• Industrial control systems
• Power supplies and inverters

Procurement Notes

Verify the specific part number suffix against official Schaffner documentation to confirm terminal type and certification status. Ensure the selected variant matches the required voltage rating and current capacity for the target application. Cross-reference datasheets for mechanical dimensions and mounting hole specifications prior to procurement.

Selection Notes

Select this model when low current requirements under 1 A are needed alongside high-performance noise suppression. Consider the chassis mounting style and fast-on termination when designing panel layouts. Verify that the leakage current specification aligns with safety standards for the intended end-use environment.

Part Context

This component belongs to the FN2090 series of single-phase EMI filters manufactured by Schaffner. The series is engineered for general-purpose applications where compact size and efficient noise reduction are prioritized. It complements other variants in the lineup that offer higher current ratings or different mounting configurations.

Replacement Considerations

FN2090B-3-06 offers similar characteristics with a higher current rating of 3 A. FN2090Z-3-06 provides flange mounting instead of chassis mounting. Verify pin compatibility and thermal performance before substituting.
