Glass and Quartz Trimmer Capacitors(Glass and Quartz Trimmers)
The unique Voltronics non-rotating precision trimmer capacitor design offers the following advantages over conventional rotating types:
The choices are:
- Linear tuning with no reversals
- A true high frequency device with high Qs, low RF losses, low constant inductance and high self-resonant frequencies
- A superior seal because the screw head and 0-ring do not move in and out
- Greater life - 10,000 cycles minimum
- Much smaller sealed MIL sizes
- Ability to provide extended metal or plastic shafts DIELECTRIC
The choices are:
- Annular Band Glass: A solid tube of a specially-selected formulation of glass which is metallized on the outside.
- Embedded Band Glass: Two tubes of glass fired together with a metallized silver band embedded between them. The inner tube is only 0.005" thick to provide much higher capacitance values.
- Quartz: A pure-grade silicon oxide offering higher Q and voltage ratings in each size with the trade-off of lower capacitance and higher cost.
