Ceramic Trimmer Capacitor Polarity

Ceramic capacitors have no polarity.

Ceramic trimmer capacitor polarity.

Refer to the dimensions concerning the polarity 1. Ceramic capacitors are most commonly found in every electrical device and it uses a ceramic material as the dielectric. A trimmer is a miniature adjustable electrical component. 1 recommended screwdriver for manual adjustment.

Therefore you are requested to approve our product specifications or to transact the approval sheet for product. It is worth noting that trimmer capacitors are not polarized. In circuits where a small size of capacitor is required ceramic capacitors comes into picture. The ceramic capacitor is a non polarity device which means they do no have polarities.

It is made of two layers of metal usually nickel and copper with ceramic para electric or ferroelectric as the dielectric. It is meant to be set correctly when installed in some device and never seen or adjusted by the device s user. Ceramic trimmer capacitors please read rating and caution for storage operating rating soldering mounting and handling in this pdf catalog to prevent smoking and or burning etc. This catalog has only typical specifications.

Other note the polarity of the trimmer capacitor to minimize infl uence by stray capacitance. Ceramic capacitors are non polarized and fixed value capacitors. As the name suggests the ceramic capacitor is a type of non polar capacitor in which the dielectric used is a ceramic material. This means that a trimmer capacitor can have a maximum capacitance two times larger than nominal.

It provides the flexibility of connecting this capacitor in the circuit. Before 1920 s due to insulating properties of mica it was used as a dielectric material in a capacitor. For this reason they re usually much safer durable than electrolytic capacitors. Trimmer capacitors do not boast a good capacitance value tolerance.

Ceramic capacitor hence this doesn t possess any polarity. So we can connect it in any direction on a circuit board. Sometimes the tolerances can be as high as 0 to 100. Use suitable screwdrivers that fi t comfortably in driver slot.

There is no polarity in a ceramic capacitor the ceramic capacitor usually uses 3 digits to represent its value like 102 103 101 for indicating its value and values in term of pico farad. Trimmers can be variable resistors potentiometers variable capacitors or trimmable inductors they are common in precision circuitry like a v components and may need to be adjusted when the equipment is serviced. In ceramic capacitor if the three digits are abc then the value would be ab 10 c pico farad. These where intially developed in german as replacement for mica.

For this reason they are generally much safer than electrolytic capacitors.
