EVM-3VSX50B14 Potentiometers, Variable Resistors

Trimmer Potentiometers

The EVM-3VSX50B14 is an adjustable trimmer potentiometer designed for a variety of field applications. The potentiometer is a three-terminal device that is adjustable from 10K ohms to 50K ohms. It is a miniature low-priced part with a low on-resistance and fast turn-on time.

Application Fields

The EVM-3VSX50B14 can be used for a wide range of applications that require precise adjustment of variable resistors. Examples include circuit tuning, calibration and testing, and voltage regulation. The potentiometer can be used in both stationary and mobile applications, such as automotive, audio, video, and medical equipment. It is particularly suitable for consumer electronics products including clocks, radios, CD players, and televisions.

Working Principle

The potentiometer works by using the principle of electrical resistance. This resistance is created when electricity passes through a resistive material such as a metal or a semiconductor. By adjusting the contact points between the two resistors, the resistance is changed and the voltage across the potentiometer is altered. This change in voltage produces a corresponding change in the current flowing in the circuit.

The EVM-3VSX50B14 uses a non-linear taper design that allows for easy adjustment of the resistor. A small screwdriver can be used to adjust the contact points between the two resistors which in turn changes the resistance of the potentiometer. Additionally, the potentiometer is sealed with a moisture-resistant coating to protect it from oxidation and environmental elements.

Advantages

The EVM-3VSX50B14 has several advantages over traditional trimmer potentiometers. It is miniature, low-priced, and has a low on-resistance and fast turn-on time. It also has great accuracy with an absolute tolerance of ±0.5%. In addition, its non-linear taper design allows for easy adjustment of the resistor. The potentiometer is also sealed with a moisture-resistant coating for extra protection.

Conclusion

The EVM-3VSX50B14 is an adjustable trimmer potentiometer designed for a variety of field applications. It is a three-terminal device that can be used for circuit tuning, calibration and testing, and voltage regulation. The potentiometer has a low on-resistance and fast turn-on time with a non-linear taper design for easy adjustment. In conclusion, the EVM-3VSX50B14 is an ideal choice for applications that require precise adjustment of variable resistors.
