Ceramic Capacitor (MLCC) Division

Since its establishment in 2019, the MLCC Division has always been committed to the R&D, manufacturing and application promotion of high-voltage MLCCs, comprehensively benchmarking Taiwan and Japanese high-end products and technologies. Now it has X7R, NPO and other product series, the voltage ranges from 1KV to 3KV, all of which are large-scale high-voltage products above 1206, and are widely used in adapters, switching power supplies, high-voltage power supplies, lighting devices and other products.



Polymer Tantalum Capacitor Division

The Polymer Tantalum Capacitor Division was established in 2022. Compared with the peers, Yongming polymer tantalum capacitors have higher capacity, lower ESR and higher withstand voltage. Products are widely used in digital servers, PCs, ultra-thin chargers, automotive electronics, communications industries, base stations, switches, industrial power modules, military power supplies and other fields. Yongming polymer tantalum capacitors replace imported tantalum capacitors, which have broad prospects and are worth cultivating.
