The potentiometer is divided into two types: vertical potentiometer and horizontal potentiometer. Suppose we regard the potentiometer as a cuboid, the vertical potentiometer is a potentiometer parallel to the direction of the welding foot and the direction of the length. On the contrary, the horizontal potentiometer is a potentiometer parallel to the direction of the welding foot and width. Whether they are vertical potentiometers or horizontal potentiometers, they all have their own advantages and disadvantages. Today we mainly tell you what advantages of vertical trimmer potentiometer are.

1. Easy ventilation and heat dissipation: no matter what kind of electrical appliances, heat dissipation problems will be one of the most headaches for product designers. Assuming that components and potentiometers are too close to each other, the heat dissipation from the side of the potentiometer can be difficult, or if the potentiometer is used too long, it can lead to serious accidents. At this time we can choose the vertical potentiometer, because the vertical trimmer potentiometer occupies a small advantage, the space between the potentiometers will be much larger. Especially in electronic products, some resistance components are relatively easy to heat, if there is no good ventilation cooling device, often lead to circuit burning short circuit problems. However, many electronic products nowadays are not only small in size but also very complex in circuit. In addition to the use of exhaust cooling devices, the gap between all electronic components can not be too small, and the arrangement should be reasonable. This can improve the life and safety of electronic products.

2. Small occupancy: Vertical trimmer potentiometer welding foot is in a small area, all welding time and the contact surface of the circuit board is relatively small, the place occupied is naturally small. Because the potentiometer is welded on the circuit board, if the circuit structure is more complex, there will be more electronic components on the circuit board, so we can choose vertical potentiometer in the row, which can reduce the potentiometer occupy the space of the circuit board. Therefore, the selection of vertical potentiometers can save a lot of space.

Installation method of adjustable variable resistor

Vertical adjustable resistor requires smaller PCB board area, which can reduce space occupation. Semiconductor radios, for example, are relatively simple and cost less and can even be soldered manually. When installing the vertical adjustable resistance, the size of PCB should be considered firstly; secondly, the power and non-power components should be considered; finally, the aesthetic appearance should be considered.

The adjustable variable resistor is composed of movable brush and resistor body. When the brush moves along with the resistor, the resistance value or voltage in contact with the displacement can be obtained at the output end. Vertical adjustable resistance has three lead-out terminals. The resistance of adjustable variable resistor is an electronic component that can be adjusted according to a certain change law. Vertical adjustable resistors can be used not only as three-terminal components but also as two-terminal components. As a two terminal component, it can be regarded as a vertical adjustable resistor.
