FN2090BZ-3-06

Overview

The Schaffner FN2090BZ-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 an inductance of 14 mH, capacitance of 330 nF, and leakage current of 0.5 mA. The unit features faston terminals and includes a 470 kΩ resistor. It functions reliably between -25°C and +100°C, with physical dimensions of 85 mm depth, 54 mm length, and 30.3 mm height.

Feature Summary

• Two-stage filtering architecture for enhanced noise attenuation
• Chassis mount design with faston quick-connect terminals
• Integrated safety resistor for discharge management

Applications

• Medical equipment power input stages
• Industrial control systems requiring low leakage current
• Electronic test and measurement instruments

Procurement Notes

Verify the specific suffix 'BZ' against official TE Connectivity Schaffner documentation to confirm chassis mounting style and terminal configuration. Ensure the 3 A rating aligns with system load requirements. Cross-reference the 470 kΩ internal resistor value if circuit discharge characteristics are critical. Confirm compliance certifications required for the final assembly target market.

Selection Notes

Select this model when a compact, single-phase filter with low leakage current is required for chassis installation. The 3 A rating suits moderate power applications. Compare inductance values against competing models if specific attenuation curves are needed. Verify that faston terminals match available connector types in the host enclosure design.

Part Context

This component belongs to the FN2090 series, which provides single-phase EMI filtering solutions. The series typically offers various current ratings and mounting options. The FN2090BZ variant specifically denotes chassis mounting with faston connections, distinguishing it from flange-mounted or PCB-mount alternatives within the same family.

Replacement Considerations

FN2090B-3-06 serves as a direct functional substitute within the same series, sharing identical electrical specifications and form factor.
