12mm A10k Potentiometer 3 Pin 500k Audio Taper Pot Amplifier

12mm diameter 3 pin single rotary potentiometer for audio amplifier, audio equipment control

Product Description

Potentiometer is a resistance element that has three leading ends and the resistance value can be adjusted according to a certain change law. A potentiometer usually consists of a resistance body and a removable brush. When the brush moves along the resistance, the resistance value or voltage is obtained at the output which is related to the displacement.
The potentiometer can be used as a three-terminal element or a two-terminal element. The latter can be regarded as a variable resistor, because its role in the circuit is to obtain and input voltage (applied voltage) into a certain relationship with the output voltage, so called potentiometer.

Application

Potentiometers are rarely used to directly control significant amounts of power (more than a watt or so). Instead they are used to adjust the level of analog signals (for example volume controls audio equipment), and as control inputs for electronic circuits. For example, a light dimmer uses a potentiometer to control the switching of a TRIAC and so indirectly to control the brightness of lamps.

Preset potentiometers are widely used throughout electronics wherever adjustments must be made during manufacturing or servicing.

User-actuated potentiometers are widely used as user controls, and may control a very wide variety of equipment functions. The widespread use of potentiometers in consumer electronics declined in the 1990s, with rotary incremental encoders, up/down push-buttons, and other digital controls now more common. However they remain in many applications, such as volume controls and as position sensors.

FAQ

1. What are the potentiometer marking methods?

Potentiometer is a variable resistor used for voltage division. One or two removable metal contacts are pressed tightly against the exposed resistance body. Contact position Determines the resistance between any end of the resistance body and the contact. Press output and input voltage ratio and the relation of rotation Angle cent linear potentiometer (show linear relation), function potentiometer (show curving relation). When a voltage is applied between the two fixed contacts of the resistance body, the position of the contact on the resistance body can be changed by rotating or sliding system, and a voltage which is related to the position of the moving contact can be obtained between the moving contact and the fixed contact. It is mostly used as a voltage divider, which is a potentiometer and is a four-terminal element. A potentiometer is basically a sliding rheostat. There are several styles, generally used in the volume switch of the speaker and the power size adjustment of the laser head. A potentiometer is an electronic component that can be adjusted. It consists of a resistance body and a rotating or sliding system.

2. What are the potentiometer marking methods?

Potentiometer mark method: potentiometer generally use direct mark method, in potentiometer housing with letters and numbers to mark their model, nominal power, resistance, resistance and the relationship between the Angle. For example: WT-ⅱ - 1-1K-X potentiometer is represented as single linked carbon film potentiometer ⅱ type, power is 1W, resistance is 1K ω, curve is straight

3.What is an adjustable potentiometer?

Adjustable potentiometer is an adjustable electronic component consisting of an individual and a rotating or sliding system. On the exposed resistance body, one or two movable metal contacts are pressed tightly, and the position of the contacts determines the resistance value between either end of the resistance body and the contacts. When a voltage is applied between the two fixed contacts of the resistance body, the position of the contact on the resistance body is changed by rotating or sliding system, and a voltage which is related to the position of the moving contact can be obtained between the rotating contact and the fixed contact.

4. What does the mechanical life of a potentiometer mean?

Potentiometer mechanical life is also called wear life, commonly used mechanical durability. Mechanical durability is to point to potentiometer in the specified test conditions, the total number of reliable movement of moving contact, commonly used "week" expressed. The kind of mechanical life and potentiometer, structure, material and make craft are concerned, difference is quite big.
