Schaffner PCB EMI Filter 6.5 A 250V AC 400Hz Single Phase PCB Mounting with Pin Termination FN402

Schaffner FN402 is a PCB-mounted EMI filter designed for single-phase circuits with a maximum current rating of 6.5 A and a voltage rating of 250V AC at 400 Hz frequency. This filter features pin termination to enable straightforward through-hole mounting on printed circuit boards.

The compact filter measures 45 mm in length, 28 mm in depth, and 16.5 mm in height, making it ideal for use in limited space environments. It offers an effective capacitance of 100 nanofarads and an inductance of 1 millihenry which together provide strong attenuation of electromagnetic interference, thus enhancing the reliability of connected electrical and electronic equipment.

The filter supports an operating temperature range from -25°C to 100°C and maintains a low leakage current of 373 microamperes, ensuring energy efficiency and safety. The low resistance of 1 milliohm contributes to minimal power loss. This product does not have any specific standards or approvals but is UL recognized, CSA certified, and VDE compliant for safety and performance.

Applications span a broad spectrum including electrical and electronic devices, small to medium-sized machinery, household appliances, switch-mode power supplies, measurement and testing apparatus, and medical equipment. It delivers good conducted attenuation performance through chokes with high saturation resistance and excellent thermal behavior.

FN402 Series filters are cost-effective with low profile design and are available in options including medical types (B type). This filter is suited for industrial, laboratory, medical, and construction environments where EMI suppression is critical to device operation and compliance.
