Application Field of RT22C2X501

The RT22C2X501 is suitable for use in a wide range of applications such as air conditioners, PCs, remote controls, digital audio amplifiers, medical equipment, LCD TVs, satellite navigation systems, automotive ECUs, as well as industry and building controls.

In remote controls it can be used to adjust the volume, brightness, and other parameters. Its precision adjustment functions make it an ideal choice for medical equipment. In air conditioners, it can be used to vary the temperature setting. Similarly, in PCs and consumer electronic systems, it can be used for fan speed adjustment and other system control parameters.

In LCD TVs, it can be used to control the video image brightness and contrast. It can also be installed in automotive ECUs and satellite navigation systems to adjust parameters like speed, acceleration, and even directions.

Working Principle

The RT22C2X501 has a variable resistor that can be adjusted manually. It works on the principle of resistance and its internal structure is made of two electrically conductive layers. While one layer works as a tracking mechanism, the other is a resistive element, and both are held together by an insulation layer.

When a voltage is applied across the resistor, a current is generated which is proportional to the resistance value of the resistor. This current value is stored by the memory controller and used to control the various parameters of the circuit. Thus the RT22C2X501 trimmer potentiometer is used for making precise adjustments in circuits and electronic systems.

Conclusion

The RT22C2X501 trimmer potentiometer from Rohm is a versatile product which can be used for a wide range of applications. It has a low profile surface mount package and is completely sealed against moisture and dust, making it ideal for use in hostile environmental conditions. Its 25-turns per revolution and ESD protection features make it highly reliable and suitable for precise adjustments in sophisticated electronic systems.
