The Bourns 3296X-1-103LF trimmer resistor is a through-hole device measuring 3/8" in size and featuring a sealed horizontal adjuster. It has a resistance value of 10Kohms and is made of two conductive terminals, usually composed of metals like nickel or gold, separated by an insulating material that provides electrical insulation between them. The device is used to adjust the resistance of an electrical circuit and can be adjusted by turning the adjuster to the left or right. It is commonly used in potentiometers, voltage dividers, and other signal-conditioning circuits.
