FN402B-2.5-02

Overview

The Schaffner FN402B-2.5-02 is a single-phase power line filter designed for PCB mounting, rated at 2.5 A and 250 VAC. It operates within a frequency range of 0 Hz to 400 Hz and features solder pin termination. The component has an inductance of 2 mH and a leakage current of 2 uA. It belongs to the FN402 series and is specifically designated for medical applications.

Feature Summary

• Designed for medical equipment applications
• Low cost PCB filter construction
• Solder pin termination for board mounting

Applications

• Medical devices
• PCB mounted power supplies
• Electronic equipment requiring low leakage current

Procurement Notes

Verify the specific suffix against official TE Connectivity / Schaffner documentation to confirm medical compliance status. Ensure the procurement specification matches the required 2.5 A rating and 2 mH inductance. Confirm that the package type aligns with the target PCB layout requirements before finalizing orders.

Selection Notes

Select this model when medical safety standards require strict leakage current limits. The 2.5 A rating suits moderate power applications. Compare with standard FN402 variants if medical certification is not mandatory, as those may offer different leakage characteristics. Verify thermal performance within the intended operating environment.

Part Context

This component is part of the FN402 series from TE Connectivity / Schaffner. The 'B' suffix typically denotes medical-grade specifications within this family. It serves as a low-cost EMI solution for single-phase AC lines. The series provides various current ratings for different power requirements.

Replacement Considerations

FN402-2.5-02 is a non-medical variant within the same series. Verify if medical certification is required before substituting. Other current ratings in the FN402B series are available for different load requirements.
