Potentiometers can be divided into precision potentiometers and sealed potentiometers.
The 3296 potentiometer is one of the series of precision potentiometers,
which can be divided into several types according to their specifications,
such as 3296X, 3296P, 3296Y, 3296Z, 3296W, etc.
Moreover, resistors with different specifications will also have differences in functional characteristics.
So generally, when we purchase a 3296 potentiometer, we cannot limit ourselves to evaluating the quality of the product solely based on price,
because the performance characteristics of the potentiometer can be comprehensively analyzed from its power, resistance, temperature coefficient, and other aspects

Chip SMD Trimming Potentiometer refers to a chip resistor whose resistance value can vary.
The main function in a circuit is to regulate physical quantities related to electricity, such as potential (voltage), current, volume, brightness, speed, etc.
It is an indispensable electrical component in a circuit.
Adjustment of SMT Potentiometers
Surface mount potentiometers generally have slots that can adjust resistance changes.
Since the slots are not very large, the adjustment tool blade must match the potentiometer slot and the torque should be appropriate,
otherwise it is easy to damage the surface mount potentiometers.
In addition, do not adjust the surface mount potentiometer randomly during maintenance to avoid expanding the range of faults and making recovery difficult.
If adjustment is required, it is best to mark the starting position of the adjustment, and the adjustment should generally not exceed 360 °

Usually, the terminal pins of a 3266 potentiometer consist of three pin contacts, one movable pin and two fixed pins.
However, during installation and wiring, the two fixed pins can be interchanged, while the middle fixed pin cannot be interchanged with the movable pin,
otherwise it will cause incompatibility between the wires and may directly damage the potentiometer.
The adjustment method of 3266 potentiometer can be achieved by inserting a flat screwdriver into the screw adjustment port,
and then turning the screwdriver can change the orientation of the chip, thereby controlling the adjustment of resistance value

Function of potentiometer
There are many types of potentiometers, and the functions of different potentiometers may vary. However, most potentiometers have three basic functions
1. First function: current control
Some precision potentiometers are capable of current control, only in this way can the current value be accurately obtained. When the selected current output end is the sliding contact lead out end,
the potentiometer can be used to control the current size;
2. Second function: distributing voltage
By utilizing the nearly linear relationship between resistance and voltage, adjusting the resistance value can adjust the voltage distribution relationship and achieve stepless output voltage regulation,
such as in humidifiers and other areas;
3. The third function is to change the resistance
When the input parameter of the circuit is the resistance value, a potentiometer can be used. When the trimmer potentiometer is connected to two end devices,
it can obtain a smooth and continuous change in resistance value within the travel range. At this time, the potentiometer plays a role in changing the resistance.
For example, in humidity control, different humidity levels are displayed by controlling the resistance value.

Cement resistance has good heat resistance, low temperature coefficient, low noise, high load power, high insulation, and non flammability. Operating environment temperature: -55 ℃~+275 ℃
Cement resistors are usually used in situations with high power and current, including 2W, 3W, 5W, 10W, 15W, 20W, 25W, 30W, 50W, and even higher power. Cement resistors are commonly used in appliances with power levels above 100 watts, such as air conditioners and televisions.
The disadvantage of cement resistance lies in its large volume, high heat generation during use, difficulty in dissipating, and often insufficient precision to meet usage requirements, stability, etc. When high power, small volume resistors, or high precision and fast heat dissipation are required, cement resistors can be replaced with JEPSUN power resistors, which can achieve power of 3W, 20W, 30W, 50W, 100W, or even higher. TO-220 and TO-247 packaging are used, with high precision, strong stability, and fast heat dissipation.
Its advantages and disadvantages:
1. Features such as shock resistance, moisture resistance, heat resistance, good heat dissipation, and low price.
2. Completely insulated, suitable for printed circuit boards.
3. Wrap wires on the porcelain rod and then weld the joints to produce precise resistance values and extend the lifespan.
4. High resistance values are made using metal oxide film (MO) instead of wire winding.
5. Excellent heat resistance, low temperature coefficient of resistance, and linear variation.
6. Durable to short-term overload, low noise, resistance value remains unchanged over the years.
7. Good explosion-proof performance, providing protection.
