FN2090Z-30-08

Overview

The FN2090Z-30-08 is a single-phase, two-stage EMI power line filter from the Schaffner FN2090 series. It features a rated current of 30A and operates at voltages up to 250VAC. The unit utilizes chassis mounting with screw terminals for secure installation. This specific variant includes optional surge pulse protection (Z type) to handle transient events. Designed for noisy applications, it offers high differential and common-mode attenuation using chokes with high permeable core material. The filter supports AC and DC applications within a compact form factor.

Feature Summary

• Two-stage design providing excellent conducted attenuation performance
• Integrated surge pulse protection for enhanced transient handling
• Chassis mount configuration with screw terminal connections
• Optimized inductivity versus amperage for increased attenuation

Applications

• Medical equipment requiring robust noise suppression
• Industrial machinery with high electromagnetic interference
• Power supplies demanding stable operation under noisy conditions
• General purpose electronic systems needing surge protection

Procurement Notes

Verify the exact suffix designation against the manufacturer's official datasheet to confirm the inclusion of surge protection features and terminal type. Ensure the chassis mounting hole pattern matches the intended enclosure design. Confirm that the 30A rating aligns with the system's continuous load requirements without exceeding thermal limits. Cross-reference certification marks such as UL or CSA if required by regional safety standards before finalizing procurement.

Selection Notes

Select this component when high current capacity combined with superior attenuation is necessary. The Z-type designation indicates integrated surge protection, distinguishing it from standard FN2090 variants. Consider the physical dimensions and screw terminal accessibility during layout planning. Evaluate the thermal performance characteristics relative to the ambient operating environment to ensure reliable long-term operation in noisy electrical settings.
