Preset 1k or 10k Ohm Trimpot (pack of 5) – Online India

Cermet preset is a compact form factor variable resistor and PCB mountable with 3 pins, and could also be fitted easily on a breadboard. The resistance or the voltage (when applied) between the terminals varies as the preset knob is rotated. You can buy online in India this 1k and 10k Ohm Preset, at Circuit Uncle – Home for robotics, embedded, IoT components, and solutions. It’s a compact and low-cost alternative to the big sized potentiometers, but with drawbacks such as the low current rating and cermet can be rotated using screwdrivers only, not by hands. Technically also called RM065, Carbon Film Potentiometer, Trimmer, or even Trimpot. These read 103 for 10k Ohm preset and 102 for 1k Ohm preset.

Variable resistors are basically used to divide a voltage or set the voltage to the desired level, as they result in a voltage divider circuit, once a voltage is applied between their terminals. The outer two pins are connected to Vcc (Generally +5V) and Ground (GND), and the center pin outputs a variable voltage when the rotary cermet is rotated.
