The 5123 series filtered inlet from Schurter is designed to meet the increasing demands for interference suppression of IT, medical, test and measurement and industrial equipment.

The filter combines an IEC power inlet and a line filter, designed for nominal currents of up to 15A. The combination power-entry unit integrates the EMC filter directly at the line input, providing an optimal effect on electromagnetic compatibility.

The device’s broad metal flange features a large amount of contact area, optimising filtering and shielding effects.

The filter’s increased inductance achieves a 6dB improvement in asymmetric attenuation compared with the 5120 series and other products on the market. As a result, the 5123 series is suitable for applications such as switched-mode power supplies, where excellent interference suppression is required.
