Procurement Notes

Verify the specific suffix code to confirm terminal type and mounting configuration, as variations exist within the FN2090 series. Confirm compliance requirements such as UL, CSA, and IEC/EN standards against the target application's regulatory needs. Ensure the operating temperature range aligns with the environmental conditions of the final assembly.

Selection Notes

Select this model for applications requiring compact, single-phase filtering with low leakage current characteristics. The 3 A rating suits low-power electronic devices. Consider the chassis mount style and faston terminals for integration into standard enclosures. Evaluate the 330 nF capacitance value against system leakage current limits.
