Binary Capacitors
Binary capacitors are ideal for tuning exact capacitance values for the absolute best performance.
Features
- Multiple pads to bond to with different capacitances
- Bond to one or more to tune specific capacitance values
- Counteracts variances in inductance/capacitance of nearby components
- 3 different form factors available
- 0.18pF to 6pF pads
*Typical resonant frequency data from application notes does not apply to this product series.
Key to Part Numbers
Our binary 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 |
