7276R20KL.25 Potentiometers, Variable Resistors

Rotary Potentiometers, Rheostats

Potentiometers and rheostats are two common types of electronic components. Their roles are similar, but there are subtle differences between them. The 7276R20KL.25 is a rotary potentiometer, which is a type of two-terminal resistor that has a third terminal connected to a movable wiper. This wiper can move across the resistive element, and as it does so, it modifies the resistance between the two end terminals, leaving the third terminal in the middle.

Potentiometers come in many shapes and sizes, but they all have the same basic design: When rotation is applied to the shaft, the wiper arm gradually moves up (or down) along the resistive element. This means that varying amounts of resistance can be placed between the two terminals, and by changing the position of the wiper, the resistance can be changed. This makes potentiometers very versatile pieces of circuit components that can be found in many applications.The 7276R20KL.25 rotary potentiometer is a great way to control voltage and current levels in many different projects. Its rated resistance is 20K ohms, with a resistance tolerance of around 10 percent. Its shaft can rotate up to 270 degrees, allowing for precise positioning of the wiper. It’s a single-turn device, meaning that the resistance will vary linearly across the resistive element. Its rated power is 3 watts, with an operating temperature range of -20 to +60 C.

Rheostats, on the other hand, are simpler two-terminal resistor components. Unlike potentiometers, they can only vary the resistance between the two terminals, as opposed to both end terminals and the wiper. As such, they are often used to control the flow of electric currents, as opposed to voltage or resistance levels. The 7276R20KL.25 rotary potentiometer is great for many applications where precise control of both current and voltage levels is needed, such as controlling the output of circuits and amplifiers, or acting as a voltage regulator for sensors and servo motors. It’s also an excellent choice for consumer electronics, such as when you need to adjust the volume on a speaker, or when controlling the fan speed of a computer system.
