How to Select Digital Potentiometers: Practical Experience Shared by Unikeyic

We can see the application of potentiometers on many devices, among which the use of digital potentiometers is more common. When we need to purchase such components, we need to compare and understand them from multiple aspects before making a choice, especially referring to industry websites such as unikeyic electronic component. Next, let's talk about the practical experience of selecting potentiometers.

Consider the occasion first, then look at the parameters：

When purchasing digital potentiometers, it is essential to select them based on the circuit situation, so consider the application scenario first, then look at the parameters. For example, in devices like radios and televisions, simple carbon film potentiometers are used, with resolution and model configurations that meet the usage requirements. Conversely, for complex circuits, you should choose rotary potentiometers.

Choosing Based on Organizational Characteristics:

When buying potentiometers, an important parameter to consider is the resistance change characteristic, which is also based on practical use. For instance, if you are purchasing a potentiometer to control volume, you should use rotary potentiometers. In most cases, linear potentiometers can be substituted for non-logarithmic potentiometers, except when selecting a potentiometer for volume control, where a linear one may not be suitable; this choice depends on specific functional requirements.

Pay Attention to Single and Dual Gang Potentiometers:

Potentiometers are available as single-gang or dual-gang variants. As previously mentioned, rotary potentiometers are typically single-gang, suitable for controlling and adjusting volume. Many complex devices utilize dual-gang potentiometers to simultaneously adjust and control two channels.

Emphasize Physical Parameter Configuration:

Naturally, when selecting potentiometers, physical parameters such as specifications, dimensions, shaft length, types of end shafts, etc., should be considered. For potentiometers that require frequent adjustment, it is advisable to choose styles with grooved structures for added stability during use.

The details and aspects to consider when choosing potentiometers have been outlined above. You can also directly screen options on Unikeyic based on your requirements. This approach allows you to access a wide range of potentiometer suppliers and choose products that not only meet your needs but also satisfy your price preferences.
