FN2090B-10-07

Overview

The Schaffner FN2090B-10-07 is a single-phase, two-stage EMI/RFI power line filter designed for chassis mounting. It belongs to the FN2090 series and features fast-on terminals for rapid installation. The component is rated for a maximum continuous operating voltage of 250 VAC at 50/60 Hz or DC, with an operating frequency range from DC to 400 Hz. The rated current capacity is 10 A at 40 °C. As a 'B' type variant, it is specifically configured without Y-capacitors, making it suitable for medical applications requiring isolation. The filter utilizes chokes with high-permeability core material to provide excellent differential and common-mode attenuation.

Feature Summary

• Two-stage filtering architecture providing high differential and common-mode attenuation performance
• Medical application configuration (Type B) featuring no Y-capacitors for enhanced safety isolation
• Chassis mount design with fast-on terminal connections for simplified assembly
• High inductivity relative to amperage for superior noise suppression within a compact form factor

Applications

• Medical equipment power supplies
• Battery chargers
• Portable electronic devices
• Energy-efficient systems

Procurement Notes

Verify that the specific order matches the 'B' suffix designation to ensure the absence of Y-capacitors required for medical isolation standards. Confirm the terminal style corresponds to the fast-on specification. Ensure the procurement documentation references the correct TE Connectivity / Schaffner manufacturer identification. Validate compliance requirements against the intended end-use environment.

Selection Notes

Select this model when medical safety regulations necessitate filters without Y-capacitors to minimize leakage currents. Choose the FN2090B series over standard variants if the application demands higher inductivity per ampere compared to the FN2060 or FN2080 series. Ensure the 10 A current rating aligns with the system's maximum load requirements at the specified ambient temperature of 40 °C.

Part Context

This component is part of the broader FN2090 family of single-phase AC/DC chassis filters manufactured by TE Connectivity / Schaffner. The series offers rated currents ranging from 1 to 30 A. While the base FN2090 provides general-purpose filtering, the 'B' suffix denotes a specialized version optimized for medical environments by omitting capacitive coupling to ground.
