Würth Elektronik is extending its portfolio of common-mode chokes with two new models. 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.
The device offers a compact design with a maximum height of 14.5mm, yet delivers an inductance up to 100mH. It can suppress common-mode interference up to 85dB, and due to its high leakage inductance, it can be employed not only for common-mode suppression but also for differential-mode suppression. The device is ideal for applications including mains-powered LED drivers, electronic ballasts, switch-mode power supplies and mains filters.
WE-CMDC is an AEC-Q200 Grade 1 qualified data line common mode choke. Measuring 11mm x 12mm x 6mm, it is also very compact. The choke offers a current-carrying capacity up to 8A and is provided with high impedances of 700, 1000 and 1500Ohms. As well as data and signal lines, applications include low-voltage DC power supplies and DC-DC converters.
