The difference between a trimmer capacitor and a variable capacitor includes the following. A Trimmer capacitor is one type of variable capacitor. The variable capacitor is one kind of capacitor. These capacitors are made with semi-circular metal plates. These capacitors are made with sets of metallic plates.
Generally, a small size means a given trimmer capacitor can fit on a PCB. The temperature range indicates the operational condition under which a trimmer capacitor can perform. Outside of this temperature range a trimmer may not perform adequately and could fail prematurely.
Trimmer capacitors typically have two main applications: initial alignment and later restoration recalibration. When all fixed components are placed in a circuit, the resulting capacitance is often not precisely what was expected. Trimmer capacitors can be used to tweak the final capacitance value to the desired nominal value.
As capacitors age, their capacitance can change. If this happens in a circuit, the trimmer capacitor can be adjusted to restore the desired capacitance. When capacitance tolerance is an issue, using a fixed-value capacitor with a tight tolerance will usually equate to a premium price. Using a trimmer capacitor may be more cost effective.
There are two types of variable capacitors available Tuning capacitor & Trimmer capacitor. These capacitors are used for tuning LC circuits of radio receivers and for impedance matching within antennas, etc.
Trimmer capacitors are available in two types air trimmer and ceramic trimmer which are discussed below. Ceramic trimmer capacitors are very small and thin capacitors that include external dimensions L x W x H as 1.5 x1.7 x 0.85 mm.

How to connect a trimmer capacitor | Electronics Forum (Circuits ...
i am trying to connect a trimmer capacitor on breadboard. but the trimmer has three pins. I know that two of the pins are connected together. does that mean I can choose one of the two connected pins as one plate of the capacitor and left the other pin as floating? the trimmer looks like this: **broken link removed**
What is a bipolar capacitor and when is it used?
A bipolar capacitor is just a non-polarized capacitor. I think the term is usually in reference to a type of electrolytic capacitor to make it clear that you can use it in any orientation since they''re usually polarized. I don''t think they''re otherwise special. At a high-level you could replace it with a ceramic capacitor of the same capacitance.
