WBSC Wire-Bondable Vertical Si Capacitors

Murata WBSC Wire-Bondable Vertical Silicon Capacitors are ideal for DC decoupling and are dedicated to applications where reliability up to +150°C is the main parameter. These Si capacitors have been developed with a semiconductor process that enables the integration of high capacitance density from 1.55nF/mm² to 250nF/mm² (with a breakdown voltage of 450V to 11V, respectively). During production, the capacitors are cured with a high temperature (above +900°C) that generates highly pure oxide. This technology offers industry-leading performances relative to the capacitor stability up to +150°C with a temperature coefficient equal to +60ppm/K. In addition, the intrinsic properties of the silicon show a low dielectric absorption and a low to zero piezoelectric effect, resulting in no memory effect.
