FN2090-1-07

Overview

The FN2090-1-07 is a single-phase EMC/EMI line filter from the Schaffner FN2090 series, designed for chassis mounting. It operates within a frequency range of DC to 400Hz and supports rated AC voltages of 110V and 250V. The component handles a continuous current of 1A and features a two-stage configuration with an inductance of 8mH. Termination is achieved via quick-connect terminals, suitable for general-purpose noise suppression applications.

Feature Summary

• Single-phase EMI/EMC filtering capability
• Chassis mount installation type
• Two-stage filter configuration
• Quick-connect termination style

Applications

• General-purpose power supply noise suppression

Procurement Notes

Verify the specific part number suffix against official Schaffner documentation to ensure correct voltage and current ratings. Confirm that the quick-connect terminal style matches your assembly requirements. Check for RoHS3 compliance status if environmental regulations apply to your manufacturing process. Ensure chassis mounting hardware compatibility before procurement.

Selection Notes

Select this model when a single-phase, low-current (1A) solution is required for chassis-mounted installations. The two-stage design provides effective attenuation for frequencies up to 400Hz. Ensure the operating environment stays within the specified temperature range. Verify that the quick-connect terminals are compatible with your wiring harness or PCB layout constraints.

Part Context

This component belongs to the FN2090 series of AC/DC chassis filters manufactured by Schaffner EMC Inc., now part of TE Connectivity. The series offers various current ratings and configurations for single-phase applications. The FN2090-1-07 specifically targets lower current needs compared to higher-rated variants like the FN2090-10-07, providing a compact solution for space-constrained designs.

Replacement Considerations

Direct substitutes include other FN2090 series variants with matching 1A ratings and quick-connect terminals. Verify pinout and mounting hole dimensions when considering cross-references. Ensure the replacement maintains the same two-stage topology and frequency response characteristics for equivalent performance.
