Rotary potentiometers and rheostats, similar electrical devices, have similar function and properties. Much like a linear potentiometer, the 7486R20KL.3 is a three-terminal component that adjusts the amount of resistance by rotating a knob. This device can be used to measure and modify voltages or currents. It is available in solder-down and surface-mount packages.

The 7486R20KL.3 features a three-terminal resistor network, with two equal terminals connected to two resistors, and the third proportional to the two. A knob is attached to the center terminal, and when rotated, alters the total resistance of the two resistors. As the knob is turned, the wiper moves along a resistive element, and at each position, the resistance between the terminals is changed in a proportion. This allows for an adjustable current or voltage to be produced, depending on the application.

The 7486R20KL.3 is primarily used in applications where accurate voltage or current control is needed. It is commonly used to adjust the operating voltage of electrical motors, or to control the power output of electrical appliances. In audio amplifiers, the 7486R20KL.3 can be used to adjust the volume or tone, by altering the electrical current passing through the speaker. This device is also used to adjust the brightness of lights, or to adjust the temperature of heating elements.

The 7486R20KL.3 is available in a range of designs, including double-ended and trimmer potentiometers. The double-ended design is two-terminal and is used when the resistance of the device needs to be changed quickly or periodically. The trimmer potentiometer is a miniature three-terminal device, whose resistance is adjusted manually using an external control such as a knob.

The 7486R20KL.3 is typically operated by adjusting the knob till the desired voltage or current is reached. At each position, the wattage rating should be within the device’s limits to maintain its longevity. The device should be handled with care, as it is sensitive to electrostatic shock. It should also be regularly cleaned to maintain electrical efficiency.

The 7486R20KL.3 is a popular device in the field of electrical engineering, as it can be used to accurately adjust voltage and current. Its durable design and low cost make it an attractive choice for a range of applications. It is suitable for use in audio and video systems, automotive electronics, and a host of other electrical projects.
