Multilayer ceramic capacitors with 100V rated voltage

TAIYO YUDEN used materials and process technologies developed by the company to improve rated voltage to 100V compared to its conventional product UMR105 B7103KV (1.0x0.5x0.5mm, with a rated voltage of 50V and a capacitance of 0.01μF), and achieve approximately a 75% reduction in size compared to the 1608-size conventional product HMR107 B7103KA (rated voltage of 100V, capacitance of 0.01μF). The product is compatible with AEC-Q200, a reliability test qualification standard for automotive passive components.

The products have been launched and will be used for power line anti-noise parts that can be used in onboard devices for automotive power trains such as engines and transmissions. Production of the multilayer ceramic capacitors commenced at the company's Tamamura Plant (Tamamura-machi, Sawa-gun, Gunma Prefecture, Japan) from December 2019 at a production rate of ten million units per month.

In recent years, electrification and electronification of automobiles have increasingly progressed in step with the proliferation of electric and hybrid vehicles. Under this situation, demands for smaller dimensions and larger capacity, together with high reliability, have also risen for multilayer ceramic capacitors that are used as automotive electronic parts.

EMC measures are required for such devices to remove external and internally generated noise to prevent malfunction, and the electronic components used inside must withstand high voltages. In addition, as devices increase in functionality and use higher-density packaging, smaller on-board multilayer ceramic capacitors are desired.

Applications include power line anti-noise parts that can be used in on-board devices for automotive power trains such as engines and transmissions.
