App note from Bourns about the robustness of trimmers used on surveillance system, typically sealed to protect agaisnt harsh environment. Link here (PDF) Trimmer technology is designed for use in applications where the unit must be calibrated before it is shipped to a retailer, and eventually the end user. Typically, these pre-calibrated electronics use a […]

App note: Potentiometers and trimmers
App note from Vishay on variable resistors primer. Link here (PDF) A potentiometer is a mechanically actuated variable resistor with three terminals. Two of the terminals are linked to the ends of the resistive element and the third is connected to a mobile contact moving over the resistive track. The output voltage becomes a function […]
