Gap Capacitors

Gap Capacitors

Gap capacitors eliminate the need for wire-bonds by enabling SMD type die attach processes.

Features

  • 2-ports (electrodes) on the same surface for top side bonding
  • Can be flip-chipped upside-down to eliminate wire bonding
  • Planar electrodes form series capacitor

*Typical resonant frequency data from application notes does not apply to this product series.

Key to Part Numbers

Our gap capacitors follow a different part numbering scheme from standard square type. Each part of the PN is structured as follows.

Metal Stacks

Depending on the ceramic dielectric used and electrode configuration, we use different metal stacks to achieve best mechanical and electrical performances. The different stacks we may use are as follows.

Electrode Metalization
Top TiW – Au OR TaN – TiW – Au
Bottom TiW – Pt – Au OR TaN – TiW – Pt – Au OR TiW – Au OR TaN – TiW – Au

Standard Sizes

Tecdia has a range of standard binary capacitors. Below are a list of some of the off the shelf parts we have available.
