FN2090A-3-06

Overview

The Schaffner FN2090A-3-06 is a single-phase, two-stage EMI power line filter designed for chassis mounting. It supports a maximum current of 3 A and operates at voltages up to 250 V AC/DC within a frequency range of 0 Hz to 400 Hz. Key electrical parameters include a capacitance of 330 nF, an inductance of 14 mH, and a bleeder resistance of 470 kΩ. The device features quick-connect terminals and exhibits a leakage current of 500 μA. Physical dimensions are 85 mm in length, 54 mm in depth, and 30.3 mm in height, with an operating temperature range from -25°C to 100°C.

Feature Summary

• Single-phase, two-stage filtering configuration for effective noise suppression
• Chassis mount design with quick-connect termination style
• Integrated bleeder resistor for safety discharge

Applications

• General purpose equipment EMC/EMI line filtering
• Power supply input protection for electronic devices
• Industrial control systems requiring noise reduction

Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm terminal type and voltage ratings. Ensure the chassis mounting hole pattern matches the application enclosure. Confirm compliance requirements such as UL or CSA certifications if applicable to the end product. Cross-reference the part number with TE Connectivity Schaffner documentation to avoid confusion with similar series variants.

Selection Notes

Select this component when a single-phase filter with a 3 A rating is required for chassis installation. The two-stage design provides enhanced attenuation compared to single-stage alternatives. Consider the physical dimensions and quick-connect terminal compatibility during PCB or panel layout. Verify that the 470 kΩ bleeder resistor meets safety isolation requirements for the specific application environment.

Part Context

This component belongs to the FN2090 series of AC/DC chassis filters manufactured by TE Connectivity Schaffner. The series offers various current ratings and mounting options. The FN2090A variant specifically denotes the chassis mount configuration with quick-connect terminals. This model is part of a broader family of EMI solutions designed for general-purpose industrial and commercial applications.

Replacement Considerations

FN2090B-3-06 is a documented alternative within the same series offering identical electrical specifications but potentially different mechanical mounting characteristics. Verify dimensional compatibility before substitution.
