Potentiometers are widely used in various industries, because of the variety, structure, installation methods and technical parameters of potentiometers are more numerous, and the performance of potentiometers with different specifications are different. So I believe that some novice purchasers must lack experience for potentiometer purchase is certainly at a loss, then the following detailed explanation of the potentiometer purchase guide and precautions.
Selection guide of potentiometers
1. When choosing
bourns potentiometer, the potentiometers with appropriate specifications can be purchased according to the occasion of application. For example, synthetic carbon film potentiometers can be used in some radio, audio, television and other circuits with low requirements, because of their complete types of carbon film potentiometers, high performance resolution, and the price is relatively cheap.
2. The resistance characteristic of
bourns potentiometer is followed, and the corresponding potentiometer is selected according to its usage. If the potentiometer is used in volume control, the exponential potentiometer is usually chosen, but in general, the non-exponential potentiometer can be replaced by the linear potentiometer, but the logarithmic potentiometer can not be used, because the logarithmic potentiometer is generally used for tone control, otherwise the linearity of the potentiometer is not selected. Compatible use will result in smaller range of potentiometer volume adjustment.
3. The is the adjustment of
bourns potentiometer and the distinction between single and double potentiometers. Generally, the single-channel potentiometer can only be used to adjust the single-channel volume, but in some audio equipment to adjust the volume of the two channels, the double-channel potentiometer needs to be selected.
4. In the process of selecting
3296 potentiometer, attention should also be paid to the size and specifications of potentiometers, the length of the handle, shaft end and other types. For some potentiometers which do not need to be regulated regularly, the potentiometer with grooves at the shaft end can be selected. The main purpose is to use a screwdriver to adjust the potentiometer and stop turning, so as to maintain the relative stability of the working state. Secondly, for potentiometers that often need to be regulated, you can choose potentiometers with their own handles to facilitate the regulation of potentiometers.
Matters needing attention in selecting potentiometers
1. When purchasing
3296 potentiometer, it is necessary to know the nominal resistance, working voltage, rated power, mechanical life and other performance parameters of potentiometers in detail. If necessary, merchants can be required to conduct on-the-spot performance tests to ensure that the quality of potentiometers is up to standard.
2. In the selection of
3296 potentiometer, not all the higher the price of potentiometers, the better their performance, if the selected potentiometers are not applicable, thus causing unnecessary waste. Therefore, the potentiometer should be selected according to the requirements of the equipment.
3. For the potentiometer price, in the conversation, we should know whether the potentiometer price contains tax or not, to avoid unnecessary disputes later.
