PTFE exhibits a higher dielectric constant than air (which is equal to unity) and can support trimmer capacitors with a much higher DC withstanding voltage rating. Therefore, multi-turn
Based on the type of dielectric chosen these are classified as 'Air Trimmer Capacitors' and 'Ceramic Trimmer Capacitors'. Among two plates one of the plates is considered to be fixed and the other is considered to be in movement or movable. The Dielectric present in this capacitor is 'Fixed'.
The minimum capacitance is usually between 0.5 pF and 10 pF, while the maximum capacitance is usually between 1 pF and 120 pF. The actual capacitance value can be varied between the minimum and maximum capacitance values for a given trimmer capacitor, but it can never be set to zero. It is worth noting that trimmer capacitors are not polarized.
Trimmer capacitors are variable components used to calibrate RF circuits during manufacturing or servicing. These components allow for variable tuning--think oscillator frequency values or rise and fall times. Should values drift over the life of the device, trimmer capacitors can be recalibrated as needed.
For higher frequency applications where a high quality factor (Q) and high series resonant frequency (SRF) are essential, multi-turn trimmer capacitors based on air, sapphire, or PTFE dielectric materials provide the lowest loss and best overall performance.
However, ceramic trimmer capacitors tend to suffer from only average temperature stability, which degrades with increasing capacitance. These components are available with a Q of about 1,500 at 1 MHz, with a nominal temperature coefficient of 0 to 750 ppm/°C. Capacitance drift tends to be about ±1% to ±5% while the maximum DWV is 220 VDC or less.
Trimmer capacitors do not boast a good capacitance value tolerance. Sometimes, the tolerances can be as high as -0 to +100%. This means that a trimmer capacitor can have a maximum capacitance two times larger than nominal. However, bad tolerances do not pose a great problem to engineers because trimmer capacitors are variable.
