IPDiA launches the first 100nF/0402 Silicon Capacitor for Ultra Broadband Systems


The UBSC capacitor series from IPDiA provide superior ultra-broadband performance and reliability, making them ideal for the requirements of the most stringent ultra-broadband applications (optoelectronics/high-speed data, trans-impedance amplifiers (TIA), receive-and-transmit optical sub-assembly (ROSA/TOSA), synchronous optical networking (SONET), as well as broadband test equipment and broadband microwave/millimeter-wave).

The UBSC capacitors are suitable for DC blocking, feedback, coupling and bypassing applications in all broadband optoelectronics and high speed data systems. The unique Si Cap technology of integrated passive devices in silicon developed by IPDiA, offers unique performances from 16 kHz to 60 GHz:

  • Ultra low insertion loss (0.5 dB);
  • Flat frequency response;
  • Excellent return loss;
  • No phase discontinuity;
  • Lower dielectric absorption (0.1%) compared to NP0/X7R;
  • Excellent stability over temperature (+/-0.5% from -55 to 150°C) and DC voltage (0.1%/V). Capacitance value stable even at 16 kHz;
  • No AC distortion due to low-to zero piezo effect;
  • Excellent reliability  exceeding  X7R ceramics by a factor 10 (FIT);
  • Reliable and repeatable UBB performances thanks to a fully controlled production line with high temperature curing (above 900°C) generating an highly pure oxide.

These ultra broadband capacitors with ultra-deep trenches in silicon have been developed using a semiconductor process which enables the integration of trench MOS capacitors providing high capacitance value of 100 nF in a 100 µm low profile 0402 SMT. Thanks to the orientation of pads underneath the component, the impedance discontinuity of transmission line can be mitigated.

“The market is continually moving to higher data transmission rates and requires an increasing number of high-performance ultra-broadband components. The 100nF/0402 UBSC ultra-broadband Si Cap has been designed to serve ultra-broadband markets for customers requiring outstanding performance from 16 kHz to 60 GHz, typical insertion loss of < 0.5 dB and a breakdown voltage of 11 VDC. The UBSC Series provide excellent return loss and unit-to-unit performance repeatability.” says Olivier Gaborieau, RF Product Line Manager at IPDiA.

The UBSC series are compliant with standard JEDEC assembly rules, making the product fully compatible with high speed automated pick-and-place manufacturing operations. Case sizes of 0201 and 0603 are also available. The UBSC capacitors are RoHS-compliant and are available with ENiG terminations.
