Silicon CapacitorsLPSC Series

Low profile capacitor down to 100µm

The LPSC target antenna matching, RF filtering and decoupling of active dies, in applications with height and volume constraints. They offer low profile (100µm thin, 80µm on request), with very high stability upon applied voltage, very low leakage current and high level of performances. These capacitors are dedicated to Smart Card, RFID tags, medical...where integration plays a key role. The LPSC product family is splitted into two series:

  • LPSC range from 47pF to 1µF, suitable for embedded technologies, modules, system in package, when designers are looking for utmost decoupling behaviour;
  • LPSC ESD Enhanced range from 47pF up to 330pF that works efficiently and durably in RFID environments. Thanks to the full modeling of the elementary cell, the ESD capabilities have been optimized up to 8kV (see Key Features below). Furthermore, our RFID Silicon capacitor range has been fine tuned in order to reach SRF up to 3GHz, hence allowing unique fine tuning of the antenna, from 13.56MHz up to UHF (800 / 900MHz) applications.

Key features

  • Ultra low profile (100μm, 80μm on request).
  • High Q.
  • Voltage stability.
  • High ESD capabilities (ESD enhanced series): >1kV for 47 pF, >2kV for 100pF, >8kV for 330pF.
  • Low leakage current down to 100pA.
  • Low ESL and low ESR.
  • SRF > 1.2GHz for 100pF.
