XBSC / UBSC / BBSC / ULSC Series

Ultra broadband surface mounted capacitor up to 100GHz

The XBSC / UBSC / BBSC / ULSC Capacitors target optical communication systems (ROSA /TOSA, SONET and all optoelectronics) as well as high speed data systems or products. These capacitors are designed for DC blocking, coupling and bypass grounding applications. The unique technology of integrated passive devices in silicon developed by Murata* offers low insertion loss, low reflection and high phase stability from 16 kHz up to more than 100 GHz for the XBSC, upto more than 60 GHz for the UBSC, up to 40 GHz for the BBSC and up to 20 GHz for the ULSC. These deep trench silicon capacitors have been developed with a semiconductor MOS process. They provide very high reliability and capacitance stability over voltage (0.1%/V) and temperature (60 ppm/K).

They have an extended operating temperature range from -55 to 150℃. Reliable and repeatable performances areobtained thanks to a fully controlled production line with high temperature curing (above 900℃) generating a highly pure oxide. The XBSC / UBSC / BBSC / ULSC series are compliant with standard JEDEC assembly rules, making theproduct fully compatible with high speed automated pick-and-place manufacturing operations. These capacitors areRoHS-compliant and are available either with ENIG terminations or lead-free prebumping depending on the case size.
