Trimmer potentiometers offer an adjustable resistance element, with the resistance typically adjusted using a non-powered screwdriver or a rotary switch. The ST4TA102 trimmer potentiometer enables designers to precisely adjust the resistance value of low-power pots without the hassle of open-loop adjustments. By using a trimmer potentiometer with contactless adjustment, designers can reduce the complexity and cost of adjusting resistance values, while taking advantage of design and performance benefits.
The ST4TA102 is a contactless, dual-in-line (DIL) trimmer potentiometer that offers two independent adjustable resistors in a single package. It is constructed of an oxide tantalum dielectric substrate, and the resistance calibration is provided automatically or manually, depending on the application\'s specific requirements. The ST4TA102 provides a wide range of adjustable resistance values between 2.5KΩ and 220KΩ, and both resistors can be independently adjusted or ganged for a single resistance value.
The ST4TA102 operates using an electromechanical principle whereby two resistors are connected in series, with one resistor functioning as the variable resistance element and the other resistor providing a constant resistance. By adjusting the gap between the both resistors, the effective resistance of the ST4TA102 is modified. The gap can be adjusted with a screwdriver, knurled nut, or a rotary switch depending on the application.
The ST4TA102 is an ideal choice for applications where precise control of the resistance is required, such as the adjustment of motor speed, input impedance adjustment of audio amplifiers, and the accuracy of precision circuits. In addition, the ST4TA102 can be used for feedback control or audio/video curve control for digital applications. It is also ideal for trimming and adjusting analog circuits as it provides a fast, reliable, and accurate method for adjusting resistance values.
The ST4TA102 is an electrical performance upgrade over traditional open-loop or manual potentiometers since it is contactless and can be easily adjusted without the need for open-loop adjustments. Its wide range of adjustable resistance makes it suitable for a variety of applications, as well as offering a cost-effective solution for resistance adjustment. The ST4TA102 is a versatile solution that offers exceptional accuracy and performance for use in precise low-power systems.
