One, the adjustable resistor's power can withstand surrounding temperatures of up to 70°C; it may lose functionality when used at temperatures above 70°C.

Avoid condensation or water droplets on the surface of adjustable resistors, and prevent use in damp areas.

The rotating force of the adjustable resistor becomes lighter as the temperature rises and tighter as the temperature drops. If the potentiometer is to be used in a low-temperature environment, it should be specified to facilitate the use of specially formulated low-temperature lubricants.

When installing the adjustable rotary resistor, do not overtighten the fixed nut to avoid damaging the threads or poor rotation.

When installing the iron shell adjustable resistor, do not use overly long screws, as this may hinder the movement of the slider or even directly damage the potentiometer itself.

Six, when applying adjustable resistors to voltage adjustment structures, it should be avoided to use current adjustment structures, as the contact resistance between the resistor and the contact plate is不利于the passage of high currents.

Seven, adjustable resistors may be damaged during welding if the welding temperature is too high or the duration is too long.

When soldering the terminals of the adjustable resistor plug, the process should be completed within 3 seconds at 235℃ ± 5℃. The soldering should be at least 1.5MM away from the potentiometer body, and avoid using solder paste that can penetrate through the circuit board.

Nine, The resistive elements of adjustable resistors are mostly made of polycarbonate synthetic resins, and they should be avoided from contact with ammonia water and other amines, otherwise, it may affect their performance.

Ten, when designing the shaft or slider for adjustable resistors, it is best to keep them as short as possible. The shorter the shaft or slider, the better the feel and stability. Conversely, the longer they are, the greater the wobble, and the more likely the feel will change.

Eleven, when soldering the terminals of surface mount adjustable resistors, avoid using water-soluble fluxes, as they can promote metal oxidation and material mold growth.

Twelve: Avoid using low-quality soldering flux as poor soldering can lead to difficulty in soldering, resulting in poor contact or short circuits.
