FN2090BZ-6-06

Overview

The Schaffner FN2090BZ-6-06 is a single-phase, two-stage EMI 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 terminals for connection and incorporates optional surge pulse protection (Z type). It features high permeable core material chokes for enhanced attenuation and includes safety resistors. The unit is rated for operation between -25°C and +100°C.

Feature Summary

• Two-stage filtering architecture providing high differential and common-mode attenuation
• Integrated surge pulse protection capability designated by the Z suffix
• Medical-grade B-type configuration ensuring low leakage current via absence of Y-capacitors
• Chassis mount design optimized for easy installation in noisy environments

Applications

• Medical equipment requiring strict leakage current limits
• Industrial machinery operating in electrically noisy environments
• Power supplies requiring surge pulse protection
• General AC/DC applications needing compact EMC filtering

Procurement Notes

Verify the specific terminal pitch and mounting hole dimensions against your mechanical design before ordering. Confirm that the B-type medical variant meets your regulatory leakage current requirements. Ensure the Z-type surge protection aligns with your system's transient voltage specifications. Check for any regional certification updates such as UL, CSA, or IEC/EN compliance relevant to your deployment location.

Selection Notes

Select this model when high attenuation performance is required in a compact form factor compared to the FN2060 or FN2080 series. The B-type designation is critical for medical applications where patient safety requires minimal leakage current. The Z-suffix indicates integrated overvoltage protection, suitable for environments with significant electrical transients. Consider the 6 A rating to ensure adequate headroom for your specific load requirements.

Part Context

This component belongs to the FN2090 series, which offers an optimized filter range for both AC and DC applications. The series is characterized by higher inductivity versus amperage, delivering increased attenuation within the same physical footprint as previous generations. It serves as a robust solution for systems demanding superior conducted noise suppression.
