FN2090BZ-8-06

Overview

The Schaffner FN2090BZ-8-06 is a single-phase EMI filter rated for 8 A and 250 V AC/DC. It operates within a frequency range of 0 Hz to 400 Hz and utilizes chassis mounting with quick-connect terminals. Key electrical parameters include an inductance of 8 mH, capacitance of 470 nF, and leakage current of 670 μA. The unit measures 113.5 mm in length, 57.5 mm in depth, and 45.4 mm in height, with a power loss of 7.7 W.

Feature Summary

• Two-stage design providing high differential and common-mode attenuation using high permeability core material chokes.
• Integrated surge pulse protection (Z type) for enhanced performance in noisy applications.
• Medical variant configuration (B type) featuring no Y-capacitors to manage leakage currents.

Applications

• Noisy AC and DC applications requiring excellent conducted attenuation.
• Medical equipment installations necessitating low leakage current configurations.
• Systems requiring integrated overvoltage or surge pulse protection.

Procurement Notes

Verify the specific suffix requirements against official datasheets to ensure correct terminal style and protection features. Confirm that the B-type designation aligns with medical safety standards if applicable. Cross-reference the Z-type surge protection specifications with system voltage ratings. Ensure chassis mounting dimensions match the enclosure constraints before finalizing procurement orders.

Selection Notes

Select this component when high attenuation is required in a compact form factor compared to previous series. The B-type version is suitable for medical environments due to reduced leakage current characteristics. The Z-type option provides necessary surge protection without additional external components. Verify thermal behavior requirements as the filter offers excellent thermal stability under load.

Part Context

This component belongs to the FN2090 series, which offers optimized filter ranges for both AC and DC applications. The series is designed for easy chassis mounting and provides higher inductivity versus amperage ratios compared to the FN2060 and FN2080 series. It serves as a multi-stage solution for stringent EMC requirements.
