FN2090B-10-06

Overview

The Schaffner FN2090B-10-06 is a single-phase, two-stage EMI/RFI power line filter designed for chassis mounting. It features a rated current of 10 A and a voltage rating of 250 VAC. The device utilizes fast-on terminals for connection and operates within a frequency range of 0 Hz to 400 Hz. Key electrical specifications include a maximum leakage current of 610 uA. The unit measures 94 mm in length, 56 mm in width, and 45.4 mm in height, with a weight of 567 g. It holds UL, CSA, and IEC/EN certifications.

Feature Summary

• Two-stage attenuation architecture providing high differential and common-mode noise suppression
• Metal enclosure construction ensuring optimal earth connection and enhanced high-frequency performance
• Medical-grade B-type configuration eliminating Y-capacitors to minimize leakage currents
• Chassis-mount design optimized for rapid installation and integration into noisy environments

Applications

• Medical equipment requiring low leakage current compliance
• Industrial machinery operating in electrically noisy environments
• Power supplies and AC/DC converters needing robust EMI filtering
• Electronic devices requiring certified conducted emission attenuation

Procurement Notes

Verify the specific suffix 'B' confirms the medical version without Y-capacitors, as standard versions may differ. Confirm terminal type matches the fast-on specification. Check for updated certification status (UL, CSA, IEC/EN) relevant to your region. Ensure chassis mounting dimensions align with your enclosure design. Validate that the 10 A rating suits your peak load requirements.

Selection Notes

Select this model when high attenuation is required in a compact form factor compared to single-stage alternatives. The B-type designation is critical for applications with strict leakage current limits, such as patient-connected medical devices. Consider the chassis mount style if panel integration is preferred over PCB mounting. Verify that the 250 VAC rating covers your system's maximum operating voltage.

Part Context

This component belongs to the FN2090 series, which offers multi-stage filtering solutions. The series provides various current ratings from 1 to 30 A and includes optional surge protection (Z type) or safety versions (A type). The FN2090B variant specifically targets medical applications by removing Y-capacitors, distinguishing it from standard commercial filters in the same family.

Replacement Considerations

FN2090-10-06 serves as a potential substitute but lacks the medical-specific B-type configuration. Verify if the absence of Y-capacitor removal in the replacement affects leakage current compliance for your specific application.
