New Common Mode Power Line Choke and Data Line Filter for Converters and Power Supplies

Wurth Elektronik has expanded its portfolio of common-mode chokes with the introduction of the THT-mountable WE-FCLP for common-mode and differential-mode suppression and the SMT data line and low-voltage common mode choke WE-CMDC.

In a compact design with a maximum height of 14.5mm the WE-FCLP achieves an inductance up to 100mH. With common-mode interference up to 85 dB, the device offers high leakage inductance, both in common-mode and differential-mode suppression. The WE-FCLP choke can be used in applications such as mains-powered LED drivers, electronic ballasts, switch-mode power supplies, and mains filters.

In a compact 11 × 12 × 6 mm package, the WE-CMDC data line common mode choke has a current-carrying capacity of up to 8 A. The AEC-Q200 Grade 1 qualified choke is available at high impedances of 700, 1000, and 1500 ohms and they can be used in applications such as low-voltage DC power supplies and DC/DC converters.
