FN2090B-6-06

Overview

The Schaffner FN2090B-6-06 is a single-phase, two-stage EMI/EMC power line filter designed for chassis mounting. It supports rated currents up to 6 A and operates at voltages of 110 VAC or 250 VAC within a frequency range of DC to 400 Hz. The component utilizes faston quick-connect terminals for circuit integration. Key electrical parameters include an inductance of 7.8 mH, a capacitance value of 330 nF, and a leakage current of 0.002 mA. It functions reliably across an operating temperature range from -25°C to +100°C.

Feature Summary

• Two-stage filtering architecture providing high differential and common-mode attenuation
• B-type configuration optimized for medical applications with minimal Y-capacitance
• Chassis mount design with faston terminal connections for rapid installation

Applications

• Medical equipment requiring low leakage current compliance
• Industrial control systems needing robust EMI suppression
• Power supply units demanding high conducted noise attenuation

Procurement Notes

Verify the specific suffix designation against official TE Connectivity Schaffner documentation to confirm the B-type variant characteristics. Ensure that the required certifications such as UL, CSA, and IEC/EN are explicitly listed for this part number in the manufacturer's datasheet before procurement. Confirm terminal type compatibility with mating connectors.

Selection Notes

Select this model when low leakage current is critical, such as in patient-connected medical devices. The B-type designation indicates specific internal capacitor configurations distinct from standard versions. Compare the 7.8 mH inductance and 6 A rating against system requirements to ensure adequate noise suppression without excessive voltage drop. Verify chassis mounting dimensions fit the enclosure constraints.
