Silicon CapacitorsHSSC Series

High stability and reliability capacitor

Thanks to the unique Murata* Silicon capacitor technology, most of the problems encountered in demanding applications can be solved. High Stability Silicon Capacitors are dedicated to applications where stability is the main parameter. The HSSC avoid the need to oversize the capacitor value for sensitive capacitive circuitry and offer a higher DC voltage stability. This technology provides industry leading performances relative to the capacitor stability over the full operating voltage & temperature range. The very high and stable insulation resistance of silicon capacitors can enhance up to 30% the battery lifetime in mobile applications. The Murata Silicon technology features a capacitor integration capability (up to 250nF/mm²) which allows a smaller case size than existing solutions to answer high volume constraints. This technology also offers high reliability, up to 10 times better than alternative capacitor technologies, such as Tantalum or MLCC, and eliminates cracking phenomena. This Silicon based technology is RoHS compliant and compatible with lead free reflow soldering process.
