WBSC / WTSC / WXSC Wire-bondable vertical Si Capacitors up to 250C Rev 2.3 Key features Key applications Low profile 250 m. Any demanding applications such as radar, lidar, aerospace, wireless infrastructure communication, data Low leakage current. broadcasting, automotive (e.g: Lidar) High stability (temperature and voltage). Applicable for standard wire bonding approach (ball and wedge), thanks to a perfect pad flatness. Negligible capacitance loss through aging. Decoupling / DC noise and harmonic filtering / Matching Compatible with standard wire bonding assembly networks (e.g: GaN power amplifier, LDMOS). (ball and wedge). High reliability applications. (please refer to our Assembly Application Note for more details) Downsizing. Low profile applications (250 m). The WBSC / WTSC / WXSC Capacitors are dedicated to applications where reliability up to 250C (for WXSC) is the main parameter. They are suitable for DC decoupling. The unique technology of integrated passive devices in silicon developed by Murata Integrated Passive Solutions can solve most of the problems encountered in demanding applications. These Si capacitors in ultradeep trenches have been developed with a semiconductor process which enables the integration of high capacitance density from 1.55 nF/mm to 250 nF/mm (with a breakdown voltage of respectively 450 V to 11 V). Our SiCap technology features high reliability - up to 10 times better than alternative capacitors technologies - thanks to a full control of the production process with high temperature curing (above 900C) generating a highly pure oxide. This technology provides industry leading performances relative to the capacitor stability up to 250C for WXSC, up to 200C for WTSC and up to 150C for WBSC with a temperature coefficient equals to +60 ppm/K . In addition, intrinsic properties of the silicon show a low dielectric absorption and a low to zero piezo electric eeff ct resulting in no memory effect . This Silicon based technology is ROHS compliant.
