Schaffner Chassis Mount EMI Filter 3 A 250V ac/dc 400Hz Fast-On 1 Phase FN2020

Schaffner FN2020 chassis mount EMI filter (model FN2020) is engineered for reliable electromagnetic interference suppression in electronic circuits and power lines. Rated for a maximum current of 3 A and voltage of 250V ac/dc, it operates efficiently at a frequency of 400Hz. The filter features a single-phase design with one stage to effectively reduce EMI noise.

The device mounts easily onto chassis with fast-on terminations, facilitating quick and secure installation in tight spaces. Its compact form factor with dimensions 64mm length, 35mm depth, and 29.3mm height allows integration into various equipment layouts.

This EMI filter provides 150nF capacitance and 2.5mH inductance values, contributing to strong attenuation performance. The filter maintains low leakage current at 740 μA and power loss of only 1.2 W, ensuring minimal impact on system efficiency. It withstands operating temperatures from -25°C to 100°C, supporting use in diverse environmental conditions.

The FN2020 series emphasizes high saturation resistance for the choke and excellent thermal behavior, making it suitable for industrial, laboratory, and manufacturing settings where EMI control is critical. This model does not have specific approvals but is built to serve general purpose EMI filtering needs.

Applications include use in power line filters for electronic assemblies, industrial machinery protection, and HVAC equipment noise suppression. Schaffner's design ensures durability and performance with a lightweight build, ideal for both new designs and retrofit projects.
