Rotary Potentiometers, Rheostats

A rotary potentiometer, or "pot", is a three-terminal resistor with a sliding contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage). The resistive element of the potentiometer is usually a spiral track of several turns of a fine wire on a permanent form, such as carbon composition, cermet, or thin film.

JC22E 5K 1% application field and working principle

The JC22E 5K 1% trimmer potentiometer, also known as a variable resistor, is a 12-turn wirewound and patented multi-turn potentiometer designed for use in manual electronic adjustments in industry, medical and consumer applications. The JC22E 5K 1% trimmer potentiometer can be used for linear and angular rotation in both CW and CCW directions. Its rotational life up to 20,000 cycles. Rated dissipative power is 0.45 W and operating temperature range is - 55°C to 85°C. The resistance range is from 5K to 10K and it has a total of 12 turns.

The JC22E 5K 1% trimmer potentiometer is typically used for low-power circuit adjustment, such as low-level signal gain regulation and volume control. It is also suitable for application in automobile instrumentation, audio amplifiers, precision heating control, digital circuits, low-voltage rail adjustments, and car audio systems. It can be used as a rheostat to control the current flow. It can also used for variable time delays, as it can vary the delay time of a circuit with a turn of the spindle.

The working principle of the JC22E 5K 1% trimmer potentiometer is based on the voltage divider principle. A voltage is applied across the two end terminals of the potentiometer, which produces a voltage across the wiper terminal that is dependent on the position of the wiper. The wiper is designed such that it can rotate around the track of Potentiometer which further increases the resistance of the wiper portion. Increase in resistance in the wiper portion results in a decreased voltage across the wiper terminal which is directly proportional to the angle of rotation.

The amount of resistance between the terminals can be adjusted by rotating the knob. The resistance between the terminals range from 5K to 10K. The voltage can be increased and decreased as the knob is rotated. The knob provides the user with a tactile feedback, which allows for precise adjustment of the resistance.

The JC22E 5K 1% trimmer potentiometer is a cost-effective and reliable solution for low-power circuit adjustment. Its 12-turn design allows for precise adjustment and long-term stability. Moreover, this product also offers long life, high reliability, and high accuracy.
