3082P-1-101LF

Trimmer potentiometers, such as the 3082P-1-101LF, are electrical components that act as adjustable voltage dividers. This particular part features 3 terminals: one is the input, the other two control the output. Rotating the component changes its resistance from 0 Ω to 100 kΩ. These components are used when precise, repeatable resistance is needed. The 3082P-1-101LF can manage a maximum continuous voltage of 160V, a power dissipation of 500mW, and a dielectric strength of 1250VAC.

Applications

This type of component has many applications across a variety of different industries. Generally, they are used in medical devices, HVAC systems, industrial automation, and high-end consumer electronics. As adjustable voltage dividers, they can be used to fine-tune the operating characteristics of resistive circuits in these applications.

Fields of Use

Trimmer potentiometers are often used in regulated circuits, such as audio preamps and amplifiers, HVAC systems, and motor control circuits. In audio applications, they are used to adjust the gain and tone of various components. In motor control applications, they are used to fine tune the speed and torque of motors. In HVAC applications, they can be used to control the flow and temperature of air.

Working Principle

At the simplest level, trimmer potentiometers work much like standard linear potentiometers. The resistance value of the device can be adjusted by changing one of the parameters of the circuit, with the output voltage changing proportional to the adjusted resistance. This is known as the voltage divider principle. In the 3082P-1-101LF, the resistor is encased in a robust plastic body that can withstand a wide range of environmental conditions. The component also features a patented tolerance-compensated design, which ensures the highest level of accuracy and repeatability.
