There are many kinds of potentiometer, but we choose the reference standard of adjustable potentiometer what, these are the need for us to consider and know, although all called potentiometer, but in its performance characteristics and parameters or some different. Today Xiaobian will tell you about the packaging characteristics of the patch adjustable potentiometer, so that you can better understand and be familiar with the classification of the adjustable potentiometer, the details are as follows:

 

   Patch adjustable potentiometer packaging in accordance with the production process of encapsulation and plastic molding packaging two, generally in accordance with the common type of use, the Patch adjustable potentiometer packaging type has a plug-in potentiometer packaging, DIP potentiometer packaging, SMD potentiometer packaging. So no matter what kind of patch adjustable potentiometer package type, potentiometer has the following parameters characteristics:

 

   1, the mechanical life of the patch adjustable potentiometer: the mechanical life of the patch adjustable potentiometer package in the future is also called the wear life, which is generally expressed with mechanical durability. Mechanical durability usually refers to the total number of reliable movement of the moving contact of the potentiometer under the specified test conditions, which is often indicated by "weeks". Mechanical life and potentiometer of the kind, structure, material and making technology concerned, so usually the difference is still relatively big.

 

   2, patch adjustable potentiometer resolution: the resolution is usually determined by the theoretical accuracy of the potentiometer package, for the wire wound potentiometer and linear potentiometer, resolution is used in the moving contact on the winding each move of a turn caused by the change in resistance and the total resistance percentage. So for the potentiometer with function characteristics, because the resistance of each turn on the winding is not the same, so the resolution is a variable. So at this time, the resolution of the patch adjustable potentiometer is usually refers to the average resolution of the maximum slope on the function characteristic curve.

 

   3, the patch adjustable potentiometer compliance: compliance is also called compliance, mainly refers to the patch adjustable potentiometer actual output function characteristics and required between the theoretical function characteristics of the degree of conformity. It uses the maximum error between the theoretical characteristics and the practical characteristics to indicate the percentage of the total voltage, so it can represent the precision of the patch adjustable potentiometer.
