Use adjustable potentiometer some considerations

Article Source:m.ljvupmm.cn  Edit:Soundwell  issuing time:2015-11-30

  Adjustable potentiometer wide range of applications, home appliances, telecommunications, automotive, digital, instrumentation, security and other fields have used in adjustable potential use should pay attention to what the problem?
  1. The potentiometer resistor mostly synthetic resin made more carbonated, should avoid contact with the following items: ammonia, other amines, aqueous alkali solution, aromatic hydrocarbons, ketones, lipids, hydrocarbons, strong chemicals (high pH) and so on, otherwise it will affect its performance.   2. The potentiometer terminals of the welding should avoid the use of capacitive water flux, otherwise it will contribute to a metal oxide material with mildew; avoid the use of poor quality solder, poor solder may cause difficulties on the tin, resulting in poor contact or disconnection.
  3. The terminal potentiometer during welding if the welding temperature is too high or too long may cause damage to the potentiometer. Pin terminals should be soldered at 235 ℃ ± 5 ℃, within 3 seconds to complete, the welding should ionization potential than 1.5MM body, do not use the solder flow through the circuit board welding; welded wire terminals should be at 350 ℃ ± 10 ℃, completed within three seconds. And the terminal to avoid stress, otherwise easily lead to poor contact.   4. When soldering rosin (flux) into the appropriate height adjustment of the press plate, flux should avoid invasive internal potentiometer, otherwise it will cause poor contact brush and resistor generates INT, noise undesirable phenomena.
  5. The voltage adjustment potentiometer is preferably applied to the structure and wiring should choose "1" feet grounded; avoid using current regulation structure because the contact resistance and the contact resistance between the sheet against by a large current.
  6. Avoid the potential surface condensation or water droplets exist, avoid damp places to prevent the deterioration of the insulation or cause a short circuit.   7. Install the "rotating" potentiometer at a fixed nut, strength should not be too tight, or turn to avoid breaking Neck and poor; installation "steel sliding straight" potential, avoid using long screws, or they may impede movement slip handle, or even directly damage the potentiometer itself.
  8. In the potentiometer knob to put the process, the use of force is not too large (parameter index can not exceed the "specifications" of the central axis of the push-pull), otherwise it will cause damage to the potentiometer.
  9. The rotary potentiometer operation force (rotating or sliding) with temperature rises lighter, with decreasing temperature and tighten. If the potentiometer is used in low-temperature environment for an explanation for the use of special low temperature grease.
  10. The potentiometer shaft or slip handle design should try to use as short as possible. Shaft or slip handle length shorter feel better and stable. Conversely the greater the longer the shaking, feel easy to change.
  11. The potentiometer carbon power can withstand ambient temperature of 70 ℃, when the temperature is higher than 70 ℃ may lose its function.   In short, the process of using an adjustable potentiometer should pay attention to the above points, Guangdong Granville Electronics Co., Ltd. specializes in manufacturing adjustable potentiometer, More product may be concerned about us.
