The main parameters of the potentiometer

Nominal resistance, zero resistance and rated power

The nominal resistance belongs to the resistance marked clearly on the potentiometer, that is, the resistance between the two fixed ends of the potentiometer; the zero resistance refers to the minimum resistance of the potentiometer, that is, the minimum resistance between the moving end and any certain end Value; potentiometer rated power refers to the maximum power allowed for long-term continuous load under the specified rated temperature when the atmospheric pressure is 87 ~ 107 kpa in AC and DC circuits.

Variation characteristics of potentiometer resistance

The change characteristic of the resistance value of the potentiometer refers to the relationship between the resistance value of the potentiometer changes with the length of the movable contact or the angle of rotation of the rotating shaft, that is, the characteristic of the resistance output function.

potentiometer resolution

The resolution of the potentiometer is also called the resolution of the potentiometer. For the winding potentiometer, when the moving contact moves each turn, the ratio of the output voltage change of the potentiometer to the output voltage is the resolution. For a linear winding potentiometer, the theoretical resolution is the reciprocal of the total number of winding turns, and it is expressed as a percentage. The more the total number of turns of the potentiometer, the higher the resolution.

Dynamic noise of potentiometer

The dynamic noise of the potentiometer refers to the electrical noise generated when the potentiometer slides on the resistor when its moving contact point slides on the resistor. Dynamic noise is the main parameter of sliding noise, and its size is related to the speed of the rotating shaft, the contact resistance between the contact point and the resistor, the uneven variation of the resistivity of the resistor, the number of moving contacts and the magnitude of the applied voltage.

What is the working principle of instant water dispenser

The first step is the water out of the tank. Our water dispensers generally need to manually fill the water tank. The specific method is that we must fill the water tank with water according to the requirements of the scale of the water tank before use, so as to meet our next use.

The second step is to achieve water output through flow control. For example, we set the water to 250ml, then after confirming at this time, the outlet flow switch will be turned on, and then accurately measure the incoming water is 250ml, this is to close the valve, so the water enters the heater position.

Reduce battery memory effect, choose from our parts of battery management. Heisener provides a wide range of quality parts for integrated circuits.

The third step is rapid heating according to the set temperature. Our instant water dispensers have a very powerful heating module. When the water enters the heating module container, it is then heated according to the water temperature we set. For example, if the waterproof level is set to 85 ° C, after the module is powered on, it will generate heat and quickly heat the water to 85 ° C.

Get to know water dispenser price in China. Our products are distinguished by creative and innovative designs, in compliance with safety and health measures.

The fourth step is the control of effluent. When the water temperature reaches the required heating temperature, the water outlet switch will open. In this way, the heated water passes through the water outlet and then is discharged. We use a cup to catch it, which completes the entire water use process. In fact, it takes a few seconds from start to finish.

Chip growth may still be very different

Leading technology companies have different forecasts for the semiconductor market in 2020. Before updating COVID-19, IDC forecasted a growth of 2%, and Gartner predicted a stronger growth of 12.5%. By 2020, IDC predicts that half-revenue will fall by 3% to 6%, while Gartner only predicts a decline of 0.9%.

Commons Workshop provides coworking . Break free from the setting of the traditional office and join us in this wonderful workspace in Wan Chai. Spark communications today with the like-minded.

In order to obtain these figures, the situation in the second half of this year will have to decline significantly from these reliable first half figures. Of course, due to concerns about the supply disruption later this year, there will be a lot of demand for chips in the near future. This may mean buying dry goods later, especially if demand is declining and customers have a lot of inventory.

Nevertheless, depending on the application of the technology, the chip growth in 2020 may still be very different.

TDA7297 is a dual-bridge amplifier specifically designed for TV and portable broadcast applications.

Assuming that in the next few months or quarters, we will have to continue to take social isolation measures, then I will see data center chips receive much attention, especially in terms of memory, storage and processing power. As people play more video games at home, as well as new Xbox and playStation consoles scheduled for release this winter, graphics chips for video games, semi-custom chips for memory and video consoles will also grow.

However, mobile phones, industrial and automotive applications are all affected by consumer purchases and economic growth, and are likely to be hit hard. This is why Microchip is the most pessimistic. Compared with the other two companies mentioned above, it has a much broader business in the industrial, automotive and consumer electronics sectors.

Therefore, I think technology investors need to choose their own location and focus on chip stocks, which will enter the data center, gaming and laptop markets in 2020. More broadly, chip manufacturers covering the industrial and automotive fields (such as Microchip) may have much weaker sales in the second half of the year.
