Murata BBSC/UBSC/ULSC Ultra-wideband SMT Silicon capacitors

Murata BBSC/UBSC/ULSC ultra-wideband SMT silicon capacitors target optical communication systems (ROSA/TOSA, SONET and all optoelectronic components) as well as high-speed data systems or products. These capacitors are designed for DC blocking, coupling, and bypass grounding applications. These silicon capacitors have low insertion loss, low reflection, and high phase stability over a wide frequency range (UBSC 16kHz to 67GHz, BBSC 16kHz to 40GHz, ULSC 16kHz to 20GHz). These deep-grooved silicon capacitors are designed using a semiconductor MOS process to provide high reliability and capacitance stability under overvoltage (0.1%/V) and overtemperature (60ppm/K) conditions.

These components have an extended operating temperature range of -55°C to +150°C. The high temperature curing process (above 900°C) produces high purity oxides that provide high reliability and repeatability. The BBSC/UBSC/ULSC series complies with standard JEDEC assembly rules and is therefore fully compatible with high-speed automatic pick-and-mount production operations. These capacitors are RoHS compliant and can be either ENIG terminated or pre-welded without leads, depending on the housing size.
