Schaffner Chassis Mount EMI Filter 4A 250V AC/DC Two-Stage Fast-On Termination FN2090

Schaffner FN2090 series EMI filter model FN2090-4-06 is a 4 ampere, 250V AC/DC two-stage chassis mount filter designed to provide superior electromagnetic interference (EMI) suppression for sensitive electrical and electronic equipment. The chassis mount configuration allows fast and secure installation using a fast-on termination style, making it ideal for industrial and commercial applications where minimizing electrical noise is critical.

This EMI filter operates effectively across a frequency range of 0 Hz to 400 Hz, supporting both AC and DC power sources. It features a capacitance of 330 nanofarads and an inductance of 14 millihenries, which contribute to its high differential and common-mode attenuation capabilities. The filter is engineered to handle maximum continuous currents of up to 4 amperes, making it suitable for low to medium power circuits.

Designed for durability, the filter supports an operating temperature range from -25°C to 100°C and has a leakage current limited to 500 microamperes, ensuring safety and energy efficiency. Its compact dimensions (85 mm length, 54 mm depth, and 30.3 mm height) enable easy integration into confined spaces on chassis or enclosures. The device has a power loss rating of 6.4 watts and a resistance of 470 kilo-ohms, indicating efficient performance with minimal heat dissipation.

Typical uses for the Schaffner FN2090 EMI filter include filtering for electrical and electronic equipment, consumer products, household appliances, automation machinery, medical equipment, electronic data communication devices, and office automation systems. Its high attenuation capabilities improve overall system reliability by reducing electromagnetic interference that could otherwise impact performance.

Produced in Thailand, this new product complies with industrial standards, ensuring quality and robust operation under demanding environmental conditions. The FN2090 series is also available in variants with medical-grade, safety, and overvoltage protection options to meet specialized application requirements.
