FN2090B-16-06

Overview

The Schaffner FN2090B-16-06 is a single-phase, two-stage EMI/RFI power line filter designed for chassis mounting. It features a rated current of 16 A and a voltage rating of 250 VAC. The component utilizes fast-on terminals for connection and operates within a frequency range of 0 Hz to 400 Hz. Designed for medical applications, the 'B' designation indicates the absence of Y-capacitors to minimize leakage current. The unit provides high differential and common-mode attenuation using chokes with high-permeability core material.

Feature Summary

• Two-stage filtering architecture providing high differential and common-mode attenuation
• Medical variant configuration without Y-capacitors for low leakage current requirements
• Chassis mount design optimized for noisy AC and DC applications
• Fast-on terminal style for straightforward electrical connections

Applications

• Medical equipment requiring strict leakage current limits
• Industrial machinery operating in electrically noisy environments
• Power supplies for sensitive electronic instrumentation
• DC to AC conversion systems within the specified frequency range

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm terminal type and certification status. Ensure the application environment matches the thermal and electrical ratings. Confirm that the medical-grade B-type construction aligns with safety standards for the intended device. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this model when high attenuation performance is required in a compact form factor compared to previous series. The B-type version is essential for medical devices where patient isolation and low leakage are critical. Consider the 16 A current rating to ensure adequate headroom for peak loads. Verify chassis mounting dimensions and fast-on terminal spacing during mechanical integration.

Part Context

This component belongs to the FN2090 series, which offers enhanced performance over earlier generations like the FN2060 and FN2080. The series provides an optimized filter range for both AC and DC applications within the same compact size. The B-type variants specifically address medical safety requirements by eliminating Y-capacitors, distinguishing them from standard industrial versions.

Replacement Considerations

FN2090-16-06: Standard industrial version with Y-capacitors; not suitable if low leakage is mandatory. FN2090A-16-06: Safety version with low capacitance; verify leakage specifications against medical requirements.
