Trimmer potentiometers, also referred to as trim pots or trimmers, are rotary variable resistors used to adjust the circuit’s current. The trimmer potentiometer or trim pot is a useful device that can be easily adjusted with a flathead or Phillips screwdriver. It’s a three-terminal device that can be used to adjust a circuit’s resistance with the turn of a knob or a screwdriver.The TC42X-2-103E trimmer potentiometer is a three-terminal, single-turn, non-linear rotary potentiometer with an adjustable resistance range of 0–1.5K ohms. It is based on wire-wound technology and uses a stainless steel core and a contact material that’s resistant to adverse environmental conditions. The package options include molded plastic surface-mount package, j-leaded package, or radial-leaded package.The TC42X-2-103E trimmer potentiometer is designed for use in a wide range of applications such as gain control, frequency control, on/off control, motor speed control, voltage regulator control, and more. It is ideal for applications where stable operation and 100% performance is critical.The main principle of operation of the TC42X-2-103E trimmer potentiometer is the same as that of the other forms of variable resistors like rheostats or potentiometers. Basically, when the shaft of the TC42X-2-103E trimmer potentiometer is turned, it changes the resistance in the circuit, thus allowing the current to flow or be stopped in various degrees, depending on the position of the shaft. The TC42X-2-103E trimmer potentiometer can be used to adjust the voltage or current in a circuit by using its three terminals, the “Common”, the “Counter-clockwise” (CCW) terminal, and “Clockwise” (CW) terminal. When the shaft is turned in the counter-clockwise (CCW) direction, the resistance in the circuit will decrease. Conversely, when the shaft is turned in the clockwise (CW) direction, the resistance in the circuit will increase.The TC42X-2-103E trimmer potentiometer has a wide range of operating temperatures, from -40 to +125°C. It has a high resistance value accuracy across its full operating temperature range and a wide full scale resistance value range, ranging from 1 ohm to 1.5K ohms. The potentiometer’s actual value can also be determined without any external circuitry, as it has an internal dividers connection.Overall, the TC42X-2-103E trimmer potentiometer is an ideal device for applications where high accuracy, stability, and reliability are critical, and it can be used to adjust the voltage or current in a circuit with the turn of a knob or a screwdriver.
