VR APPLICATION INSTRUCTIONS
Use of chemicals:Synthetic ressuns such as polycarbonate are used in the potentiometer. Care must, therefore, be exercised not expose the pesistor to thick atmosphere of ammonia, amins, alkali solution, aromatic hydocarbon,ketons, esters, halogenous hydrocarbons, etc.Use of flux:When soldering avoid using water-soluble flux. Otherwise, it might cause an adverse effect on moldingmaterial and metal.Soldering:Saldering operation must be completed in a time as sonn as possible suggested maxinum soldering-iron tiptemperature and allowable time is at 270 for 3 seconds. Avoid wiring and soldering that causes solder to flow out to the top of PC board as shown. A contact failure may occur in the terminal section.Dew condensation: Avoid using the potentiometer where dew or water drops might occur on the surface of the resistor,etc;insulation deterioration or shorting may occur.Prevention of ground noise:Single-unit potentiometers are generally constructed to be resistant to ground noise, butmulti-ganged types, shaft-moving(back and forth)types and car-audio-use types do not have such a feature. For use with high-gain sets, please consult us.Operation at low temperature:To assure smooth rotation of a potentiometer at extremely low temperature, which might be encountered in a car radio or car stereo, special low-temperature grease may be applied to moving parts in the potentiometer upon request. The rotational torque of a low-temperature potentiometer is given in the table below.
Rotatable
| Temperature | Rotational torgue |
| -20℃ | 80mN.m max |
| -30℃ | Rotatable |
7,Chassis mounting:Avoid using the screw longer than a specified one. Otherwise, the amont of travel may be reduced
or the potentiometer may be damaged if the lever is located at the end.feeling will be obtained.
