1K 3386P Trimpot Trimmer Potentiometer (Pack of 5) 1k 3386P Trimpot is a high accuracy variable resistor and PCB mountable with 3 terminal pins. A general-purpose board mountable preset also called by other names like potentiometers, Trimpots, etc but is just a variable resistor. The voltage between the terminal varies as the trimpot is rotated. The Variable resistors are used for variating voltage as per the need in a circuit. The outer two pins are connected to Vcc and 0V, and the center pin outputs a variable voltage between 0v and Vcc as the rotary cermet is rotated. The potentiometer is easy to mount on a PCB and can be adjusted using a screwdriver. This potentiometer has a single turn, which can be used to preset a value. Applications Can be used to adjust the voltage drop in the circuit Measurement and Test of electronic circuits Can be used to control the intensity of led lights in DIY projects
