UWSC Ultra Large-Band Wire-Bondable Si Capacitors Murata UWSC Ultra Large-Band Wire-Bondable Silicon Capacitors target optical communication systems (ROSA/TOSA, SONET and all optoelectronics) as well as high-speed data systems or products. The UWSC components are designed for DC decoupling and bypass applications as the capacitors offer high rejection at frequencies higher than 26GHz. The UWSC capacitors are manufactured with both deep trench and MOS semiconductor processes to cover low and high capacitance requirements.
