WE-CLFS Series Line Filters

Wurth Electronics' WE-CFLS series is a complete line filter solution offered in three different types including single-stage, single-stage advanced, and two-stage. The single-phase filters feature broadband noise suppression in common and differential modes. The rated voltage of the WE-CLFS series is 250 V (AC/DC). The single-stage modules have an ultra-compact design and contain a discharge resistor, an X-capacitor, a common-mode choke, and two Y-capacitors. The single-stage advance modules differ, with an additional X-capacitor and improved differential mode noise attenuation. The two-stage modules add another common-mode choke and another X-capacitor which allows extreme differential and common mode noise attenuation. The WE-CLFS series is perfect for use in industrial electronics, switch-mode power supplies, and telecommunication applications.
