FN402-1.6-02

Overview

The Schaffner FN402-1.6-02 is a single-phase power line filter designed for PCB mounting via through-hole solder pins. It supports a rated current of 1.6 A and a voltage rating of 250 VAC at frequencies from 0 Hz to 400 Hz. Key electrical parameters include a capacitance of 100 nF, an inductance of 6 mH, and a leakage current of 373 µA. The component complies with UL, CSA, and IEC/EN standards.

Feature Summary

• Provides electromagnetic interference suppression for single-phase AC power lines
• Designed for low-cost printed circuit board integration using through-hole technology
• Certified for international safety compliance including UL, CSA, and IEC/EN standards

Applications

• Single-phase AC power input stages in commercial electronic equipment
• Power supplies operating within the 50/60 Hz or 400 Hz frequency ranges
• Applications requiring certified EMI filtering on printed circuit boards

Procurement Notes

Verify the manufacturer part number matches exactly: FN402-1.6-02. Confirm the supplier is TE Connectivity / Schaffner. Ensure the package type is through-hole solder pin and the rating is 1.6 A / 250 VAC. Check for RoHS compliance status as indicated in official documentation.

Selection Notes

Select this component when a single-stage EMI filter is required for single-phase circuits up to 1.6 A. It is suitable for applications needing 100 nF capacitance and 6 mH inductance. Consider the 373 µA leakage current limit for sensitive medical or low-power designs. Verify that the 250 VAC rating meets the system voltage requirements.

Part Context

This component belongs to the Schaffner FN402 series of low-cost PCB-mounted power line filters. The series includes variants with different current ratings such as 0.5 A, 1 A, 2.5 A, 4 A, and 6.5 A. These filters are engineered for compact integration into electronic devices requiring basic EMI suppression.

Replacement Considerations

Other models in the FN402 series may serve as substitutes if current ratings differ, such as FN402-1-02 (1 A) or FN402-2.5-02 (2.5 A). Verify that the replacement maintains the same 100 nF capacitance and 6 mH inductance values to ensure equivalent filtering performance.
