When compared to other variable capacitors, vacuum variables tend to be more precise and more stable. This is due to the vacuum itself. Because of the sealed chamber, the dielectric constant remains the same over a wider range of operating conditions. With air variable capacitors, the air moving around the plates may change the value slightly; …

This will be found almost exclusively in the rough vacuum range.The character of this type of flow is determined by the interaction of the molecules. Consequently internal friction, the viscosity of the flowing substance, is a major factor. A further rise in Δp > Δp crit would not result in any further rise in gas flow; any increase is inhibited. ...
Trimmer capacitors come in various types, including air trimmer capacitors, porcelain-trimmed trimmer capacitors, organic film trimmer capacitors, and mica trimmer capacitors. They are commonly used as compensation or correction capacitors in tuning and oscillation circuits, where precise capacitance values are …
Where E is the electric field, F is the force exerted on a particle introduced into the field and q is the charge of the particle. The unit for electric field is volts per meter [V·m-1] or newtons per coulomb [N·C-1]. Q Factor The quality factor or Q factor of a capacitor, represents the efficiency of a given capacitor in terms of its energy losses.
5 distortion temperature is 250 C for PPS, while PBT is deformed at 190 C. Ultimately, PPS is the material of choice for higher grade temperature, humidity, bias (THB) film capacitors. After the housing, epoxy is the second line of defense to protect the capacitor.
