- Key Products/Technologies
- MLCC (Multilayer Ceramic Capacitor): Offering a wide range of sizes and capacitance, including Standard, Soft Termination, Open Mode, and Floating Mode types. This is a core business segment, successfully developed and mass-produced with proprietary technology since 1985, possessing capabilities for advanced development of ultra-compact, ultra-high capacitance, and ultra-high voltage products. Automotive MLCCs, initially supplied for infotainment systems, are now provided for high-value powertrain MLCCs used in Tesla electric vehicle drive inverters. The importance of MLCCs is growing with increased demand from cutting-edge electronic products like AI servers.MLCC (Multilayer Ceramic Capacitor): Offering a wide range of sizes and capacitance, including Standard, Soft Termination, Open Mode, and Floating Mode types.
