IPDia - 60+GHz Ultra Broadband Silicon SMD Capacitors

IPDia - 60+GHz Ultra Broadband Silicon SMD Capacitors

UBSC/ULSC Capacitors target Optical communication systems such as ROSA/TOSA, SONET and all optoelectronics as well as High speed data system or products. They are suitable for DC blocking, feedback, coupling and bypassing applications in all broadband optoelectronics and High speed data systems. The unique technology of integrated passive device in silicon, developed by IPDiA, offers unique performances with low insertion loss, low reflection and phase stability from 16 kHz up to 60+ GHz for the UBSC/UBEC and up to 20+ GHz for the ULSC/ULEC.

These deep trench silicon capacitors have been developed with a semiconductor MOS process, providing a high capacitance value of 100 nF in a SMT 0402. The purity of the oxide cured at a temperature of 900°C during the manufacturing process plays a major role on the Ultra Broadband Si Cap characteristics. The UBSC capacitor provides very high stability of the capacitance over temperature, voltage variation as well as a very high reliability. UBSC capacitors have an extended operating temperature ranging from -55°C to 150°C, with very low capacitance change over temperature (+/- 0.5%). The Silicon substrate brings lower dielectric absorption and low to zero piezo effect. Standard form factors are 0201, 0402 & 0603 with values ranging from 10 nF to 100 nF.
