Description:

A trimmer potentiometer is a variable resistor that is designed to be infrequently adjusted, usually just at the point of manufacture or when the unit is being recalibrated. They are placed along the circuit at critical points that need to carefully tuned for optimal functionality. Usually, a small screw at the top of the resistor body makes the resistance adjustment. The body itself is mounted directly onto the board. Because they are calibrating devices, their resistive range is often very small, and very accurate settings can be achieved through adjustment.

Electrical specifications

Others:

Rotation life: After 10,000 rotation, the changes impacted no more than ± (15% R +0.5 Ω ) rotational noise not more than 100 mv

Terminal strength: After welding (350 °C, 3,5 seconds) , the termination of terminal contacts should be good, no loosening of.

Soldering ability: Dip the terminals into tin tank at 260°C±5°C for 2±0.5 seconds, the soldering area should be more than 90%.

Working principle:

Potentiometers and rheostats are variable resistors constructed with a three terminal form. Two of the terminals are attached to each end of the resistor, like a normal fixed resistor structure. The third terminal is connected to a device called a slider. This is a conductive wiping mechanism that can be swept across the resistor in a semi-continuous pattern and create a conductive pathway between the end terminals and the wiper terminal. They can be designed to have a different resistive output depending on the location of the adjuster knob or slider. Some are designed to have a linear output and others, especially in audio functions, have outputs resembling logarithmic scales.
