Bourns potentiometer is one of the brands of electronic components in the United states, and is also a world-renowned manufacturer and supplier of electronic components. If you need to buy bourns potentiometer, you should take a good look at the following tips for buying bourns potentiometer. A Bourns potentiometer can meet the following procurement standards, so you can almost choose.

Selection of Bourns potentiometers

1. Choose according to the skill function of Bourns potentiometer.
Because bourns potentiometer is made of different materials and different manufacturing techniques, the skills and functions of Bourns potentiometers are different.
Wire-wound Bourns potentiometer has the characteristics of low touch resistance, high precision, low temperature coefficient, and can be used to manufacture low-power and high-power types with large distributed inductance and capacitance, so it is not suitable for high-frequency circuits. In particular, the high resistance Bourns potentiometer, the resistance wire is very thin, and it is easier to break. In addition, its nominal resistance is low, usually less than 100K ohm. Its defect is poor resolution, because the moving contact sliding friction, resistance wire easily broken, so poor reliability.

2. According to the construction method and adjustment method of Bourns potentiometer.
The bourns 3296 potentiometer is an adjustable electronic component, so it is usually called an adjustable resistor. The switch number of Bourns potentiometer with switch can be divided into single-pole single-throw, single-pole double-throw, double-pole double-throw and so on.
For example, in the correction circuit, the locking type bourns 3296 potentiometer can be used. In the transistor amplifier bias circuit, a semi adjustable Bourns potentiometer can be used. In stereo equipment, the need to adjust the volume and tone of the two channels together, the use of dual bourns 3296 potentiometer. In the automatic control circuit such as computer and servo control, multi ring Bourns potentiometer can be used. In addition, we should also consider whether the length of the shaft is appropriate, the method of selecting the end of the shaft, the milling plane is still with grooves and so on.


Purchasing skills of Bourns potentiometers

1. Type, size or stroke.
To buy Bourns potentiometers, the first thing to understand is the type or type of Bourns potentiometer. So here's the general direction, which is whether this is a dial Bourns potentiometer or a spin Bourns potentiometer or a straight-sliding Bourns potentiometer, or just something else. After confirming, can we confirm the dial Bourns potentiometer is single or double? What are the basic parameters? Only by identifying these first can we have a general pattern. And this is the fundamental factor that affects prices.

2. the use of Bourns potentiometer
That is, before you purchase, you know clearly what you are buying this Bourns potentiometer. At the same time, it is best to know whether it is used for dimming, adjusting speed or adjusting sound. All these will affect the quality of production.

3. whether there is a paragraph or not.
See if the Bourns potentiometer is rotated to the center of the positioning, general sliding Bourns potentiometer will encounter this problem, some with a handle rotating Bourns potentiometer will also have this problem

4. the way of wiring.
What is the connection between the Bourns potentiometer and the circuit board, whether it is welded wire or inserted directly into the circuit board, etc.

5. Terminal form
It depends on whether the terminals are straight or curved terminals. Or look at the angle between the terminal and the handle. Generally 180 degrees are straight feet, 90 degrees are bends.

6. Shaft type or sliding handle type or dial type and size length.

7. Solder mode
