Schaffner Single-Phase PCB EMI Filter 3A 250V AC 400Hz Pin Termination FN405

Schaffner FN405 is a single-phase PCB EMI filter designed to provide efficient filtering for electrical and electronic equipment. This filter supports a maximum current of 3A and operates at 250V AC with a frequency of 400Hz, making it suitable for applications requiring reliable EMI suppression on single-phase power lines. With pin termination and PCB through-hole mounting, it ensures easy and secure installation on printed circuit boards.

The filter features a robust plastic housing with a low profile, measuring 36mm in length, 31mm in depth, and 19.5mm in height, making it compact enough for integration into small to medium-sized machines, household appliances, switch-mode power supplies, and test & measurement instruments. It operates safely in a temperature range from -25°C to 100°C, demonstrating excellent thermal stability.

Performance-wise, the FN405 series utilizes chokes with high saturation resistance to maintain good conducted attenuation and excellent thermal behavior. The filter's capacitance of 15nF and inductance of 2mH effectively reduce electromagnetic interference, with a leakage current of 373μA ensuring electrical safety and compliance.
